5. Elmer really likes to cook with onions and he puts onions into almost everything he makes. He usually starts dinner every day around 5:00 p.M. As he is cutting the onions, the grandfather clock chimes five times because it is 5:00 p.M. Elmer is also crying because cutting the onions makes his eyes water. One evening he is at a friend's house because they are going out to dinner later. He and his friend are watching TV and the clock chimes five times when it is 5:00 p.M. Elmer's eyes start to water.
Answers
Answer and Explanation:
A) Unconditioned Stimulus- The onion
B) Unconditional Response- Crying
C) Conditioned Stimulus- Chiming clock
D) Conditioned Response- Crying
In the above scenario( an example of classical conditioning), Elmer has been conditioned by the continuous iterations of having to cook everyday by 5pm. He cooks with onions by 5pm around the same time his uncle's clock chimes five times. He cries/has teary eyes(unconditioned response) because of the response to the onions(unconditioned stimulus) around the same time the clock chimes five times thereby conditioning his response so that even when the onions isn't there/he isn't even cooking, he tears up to the clock chimes around 5pm. The clock is therefore a conditioned stimulus and there is a conditioned response of crying.
The unconditioned response to an unconditioned stimulus happens naturally(an instinct) because it is a biological response to the onions, not conditioned.

What is an element?
An element is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.
Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.
The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.

Be sure to answer all parts.The equilibrium constant Kc for the reaction below is 61.5 at a certain temperature. H2(g) + I2(g) ⇆ 2HI(g) If you start with 0.155 M hydrogen iodide, what will the concentrations of H2, I2, and HI be at equilibrium?
Answers
Answer:
[tex][I_2]=[H_2]=0.0157M[/tex]
[tex][HI]=0.124M[/tex]
Explanation:
Hello!
In this case, for the undergoing chemical reaction, we can write the equilibrium expression as shown below:
[tex]Kc=\frac{[HI]^2}{[I_2][H_2]}[/tex]
However, since the reactions starts with 0.155 M hydrogen iodide, we need to invert the reaction as well as the equilibrium expression:
[tex]2HI\rightarrow I_2+H_2[/tex]
[tex]\frac{1}{Kc}=0.0163 =\frac{[I_2][H_2]}{[HI]^2}[/tex]
And each concentration at equilibrium in terms of the reaction extent is:
[tex][I_2]=[H_2]=x[/tex]
[tex][HI]=0.155-2x[/tex]
Thus, plugging in the new expression we write:
[tex]0.0163 =\frac{x*x}{(0.155-2x)^2}[/tex]
Which has the following valid solution for [tex]x[/tex]:
[tex]x=0.0157M[/tex]
Because the other solution is negative. Therefore, the concentration of hydrogen, iodine and hydrogen iodide at equilibrium turns out:
[tex][I_2]=[H_2]=0.0157M[/tex]
[tex][HI]=0.155-2(0.0157)=0.124M[/tex]
Best regards!
At the equilibrium, the concentration of hydrogen and iodine has been 0.0157 M each, and the concentration of HI will be 0.124 M.
The initial concentration of the reactant has been 0.155 M. From the balanced chemical equation, the ICE table will be:
HI [tex]\rm H_2[/tex] [tex]\rm I_2[/tex]
I 0.155 0 0
C -2x x x
E 0.155 - 2x x x
The value of the equilibrium constant can be given by the ratio of the concentration of products to the reactant.
The equilibrium constant for the reaction will be:
[tex]\rm k_c\;=\;\dfrac{[H_2]\;[I_2]}{[HI]^2}[/tex]
The given constant value has been for the opposite reaction. Thus the constant for the required reaction has been :
[tex]\rm \dfrac{1}{given\;k_c} \;=\;\dfrac{[H_2]\;[I_2]}{[HI]^2}[/tex]
[tex]\rm \dfrac{1}{61.5}[/tex] = [tex]\rm \dfrac{(x)\;(x)}{(0.155-2x)^2}[/tex]
0.0162 = [tex]\rm \dfrac{x^2}{(0.155-2x)^2}[/tex]
By simplyfying the equation,
x = 0.0157 M
At the equilibrium, the concentration of hydrogen and iodine has been 0.0157 M each.
The concentration of HI will be:
HI = 0.155 - 2x
HI = 0.155 - 2(0.0157)
HI = 0.124 M.

why can molecules made of three atoms have a bent or linear shape?
Answers
Answer:
Bent = Linear but bent due to the Lone Pairs that it contains, the more Lone Pairs the greater the bent and the smaller the degree. It is 3 atoms total.
The discussion on bent/linear shape, and its further calculation can be defined as follows:
Linear form molecules containing atoms arranged inside a straight line.Molecules having linear electron-pair geometries have sp hybridization so at central atom.Bend molecular geometry, often called angular or V-shaped, relates to molecules that have a non-collinear organization of 2 adjacent bonds.Bent = Linear however bent given the presence of Lone Pairs; more the Lone Pairs, then higher the bent as well as the smaller its degree. This consists of 3 atoms in total.Learn more:

A teacher did an experiment to show the movement of particles in solids, liquids, and gases. The experiment is shown below. The teacher pulled the string attached to the stretched balloon, first slowly. Then fast and finally vigorously
Answers
Answer:
This question is incomplete. However, the completed question is below
A teacher did an experiment to show the movement of particles in solids, liquids, and gases. The experimental set-up is shown below: An inverted glass jar is shown. Small circles representing foam balls are shown inside the jar. A stretched balloon is shown tied at the mouth of the jar. A string is shown drawn out from the middle of the stretched balloon. A hand is shown pulling the drawn out string. The teacher pulled the string attached to the stretched balloon, first slowly, then fast, and finally vigorously. Which of the following is most likely correct about the pulling of the string and the corresponding state of matter being represented? (a) Gas is represented when pulled fast, solid when pulled slowly, liquid when pulled vigorously. (b) Gas is represented when pulled slowly, liquid when pulled fast, solid when pulled vigorously. (c) Solid is represented when pulled slowly, liquid when pulled fast, gas when pulled vigorously. (d) Solid is represented when pulled vigorously, liquid when pulled fast, gas when pulled slowly.
The correct answer is C
Explanation:
These question has to do with the "freedom" of particles in each state of matter. In solids, the particles are compact and do not move freely within the solid molecule hence the reason for the definite shape of solid. The particles of liquids move more freely than solid but not as much as gases, hence the reason for there free flowing nature. Particles of gases move more fast and rapidly; colliding against one another and the wall of the container.
From the above description, it can be deduced that to illustrate these particles the teacher will have to represent the particles of the solid as been moved slowly, particles of the liquid will be pulled fast and that of gas will be pulled vigorously using balloons. Thus, the correct option is C
Answer:
the correct answer is c!
Explanation:
Solid is represented when pulled slowly, liquid when pulled fast, gas when pulled vigorously.

O 7 amu
O 6.9 amu
O 6.93 amu
O 6 amu
Answers
Answer:
Average atomic mass = 6.93 amu.
Explanation:
Given data:
Percent abundance of lithium -6 = 7%
Percent abundance of lithium - 7 = 93%
Average atomic mass of Li = ?
Solution:
Average atomic mass = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass) / 100
Average atomic mass = (7×6)+(93×7) /100
Average atomic mass = 42+ 651 / 100
Average atomic mass = 693/ 100
Average atomic mass = 6.93 amu.

C. trans-Saharan trade network.
D. Songhai trade network.
Answers
Answer:
It is NOT B (Silk Road trade network), I repeat NOT B, but I think it could be A (Indian Ocean trade network)
Explanation:
I took the quiz and chose B (Silk Road trade network) and it was INCORRECT. As for A (Indian Ocean trade network), I looked back at the lesson and it doesn't mention anything about D (the Songhai trade network), which rules that one out, so now it's between A and C. I don't think it's C (trans-Saharan trade network) because although it was near the Arabian Peninsula, it said that it trades with civilizations in the Saharan Desert and people who live near the Mediterranean Sea. It also said nothing about trading with Europe (Roman Empire at that time) along the trans-Saharan trade network. So that's why I'm thinking it could be the Indian Ocean trade network because 1. it's the only one that makes sense after we've ruled out the others 2. It traded with the Arabian Peninsula, and since it traveled over water, I'm thinking it could've gotten to Europe. Then again I could be wrong, but keep these in mind while answering.

When you sweat a lot the water content of your blood can drop. Your cells have to maintain a certain level of water and salt in order to function properly. Which systems work together to help maintain homeostasis.
Answers
Answer:
Explanation:
There are key organs and system that assist in ensuring the body maintains homeostasis in the case of water-salt balance.
The excretory system: When one sweats, a lot of water content of the blood can drop (this is what causes the individual to be thirsty). In order to maintain a certain water-salt balance, the excretory system passes some salt out of the body in the form of urine (this is the reason the urine is usually yellowish but small in volume during the summer).
Endocrine system: When water content of the blood drops, vasopressin (also called antidiuretic hormone) is released into the bloodstream stimulating the kidneys to conserve water and release less urine (as said earlier). However, if the body is hydrated, less vasopressin is released and more water is passed in the urine.

If an element has 10 protons and 11 neutrons and 10 electrons, which expression correctly identifies the element? Atomic numbers: Sodium is 11, Neon is 10
Answers
Answer:
Explanation:
Firstly, it should be noted that atomic number (number of protons) determines element. And the element with the atomic number 10 (10 protons) is Neon. Hence, Neon-10 (₁₀Ne) is the answer.
Note that sodium has an atomic number of 11. Also, number of protons is usually equal to the number of electrons in neutral atoms, this is because the total number of positive particles (protons) must be equal to the total number of negative particles (electrons) to give a neutral atom.
