Explanation:

a) The total ionic equation shows all the ions involved in the equation as follows;

H^+(aq) + I^-(aq) + Li^+(aq) + OH^-(aq) ----> Li^+(aq) + I^-(aq) + H2O(l)

b) The net ionic equation only involves the ions that truly participated in the reaction.

If some salt were accidently spilled as it was transferred from the balance to the cup would your calculated enthalpy of solution of the salt be too high or too low

Answers

Answer:

It would be to low

Explanation:

If some salt were accidently spilled as it was transferred from  balance to  cup  calculated enthalpy of solution of salt be too low as there will be loss in mass  which would lead less solubility of salt and hence less enthalpy.

What is solubility?

Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.

The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.

how many ml of 10.0 m cacl2 do we need to prepare 3.00 l of a 0.500 m cacl2 solution

Answers

Answer:

150 mL

Explanation:

From the question given above, the following data were obtained:

Molarity of stock solution (M₁) = 10 M

Volume of diluted solution (V₂) = 3 L

Molarity of diluted solution (M₂) = 0.5 M

Volume of stock solution needed (V₁) =?

The volume of stock solution needed can be obtained as follow:

M₁V₁ = M₂V₂

10 × V₁ = 0.5 × 3

10 × V₁ = 1.5

Divide both side by 10

V₁ = 1.5 / 10

V₁ = 0.15 L

Finally, we shall convert 0.15 L to mL. This can be obtained as follow:

1 L = 1000 mL

Therefore,

0.15 L = 0.15 L × 1000 mL / 1 L

0.15 L = 150 mL

Therefore, the volume of the stock solution needed is 150 mL

There are three fundamental subatomic particles, these are;neutrons protons and electrons.

Ernest Rutherford successfully showed that every atom does possess a central core that contain positively charged particles (protons) called the nucleus. Chadwick later discovered the existence of neutrons.

Both protons and neutrons are found in the nucleus. Z represents the nucleus of the boron atom and houses the neutrons and protons of the boron atom.

What is the number of moles of glucose (C₆H₁₂O₆) in 0.500 L of a 0.40 M solution?

Answers

Answer:

0.20 moles

Explanation:

In order to solve this problem it is necessary to keep in mind the definition of molarity:

Molarity = moles / liters

If we input the data given by the problem we're left with:

0.40 M = moles / 0.500 L

Meaning that we can proceed to calculate the number of moles:

moles = 0.40 M * 0.500 Lmoles = 0.20 moles

The number of moles of glucose ([tex]C_6H_{12}O_6[/tex]) in 0.500 Liters of a 0.40 M solution is 0.2 moles.

Given the following data:

Molarity of solution = 0.40 MVolume of solution = 0.500 L

To determine the number of moles of glucose ([tex]C_6H_{12}O_6[/tex]) in 0.500 Liters of a 0.40 M solution:

Mathematically, the molarity of a solution is given by the formula:

[tex]Molarity = \frac{number\;of\;moles}{Volume \;in\;liters}[/tex]

Making number of moles the subject of formula, we have:

[tex]Number\;of\;moles = Molarity \times Volume[/tex]

Substituting the given parameters into the formula, we have;

[tex]Number\;of\;moles = 0.40 \times 0.500[/tex]

Number of moles = 0.2 moles.

Answers

Answer:

My name is Andreas Vesalius and I'm a 16th-century Flemish anatomist, physician, and author of one of the most influential books on human anatomy, De Humani Corporis Fabrica Libri Septem. I am often referred to as the founder of modern human anatomy. I was born in Brussels, December 31, 1514 which was then part of the Habsburg Netherlands. I was a Flemish doctor who was notable for my contribution to the science of anatomy of the human body. I was the first to perform public dissection on a human corpse, a practice that was unusual in the Middle Ages due to spiritual beliefs.

A

B
The light was too strong for the paint
с
The sun removed energy from the paint
D
The paint absorbed the energy from the light

Answers

Answer:

I believe that the answer is the paint absorbed the energy from the light

Explanation:

The paint dried because the paint absorbed the energy from the light and the correct option is option D.

What is absorption of light?

Light absorption is the process in which light is absorbed by matter and converted into energy. In an atom, electrons vibrate at a specific frequency – this is called the natural frequency.

If a wave of light hits a material in which the electrons are vibrating at the same frequency as the wave of light, the electrons will absorb the energy and convert it into vibrational motion.

This is why objects have different colours – different materials’ electrons will vibrate at different rates, and therefore absorb different frequencies of light.

Therefore, the paint dried because the paint absorbed the energy from the light and the correct option is option D.

What volume is occupied by 3.12 moles of a gas when the pressure is 88.4 kPa at a temperature of 19℃?

Answers

Answer:

The Combined Gas Law shows that the pressure of a gas is inversely proportional to volume and directly proportional to temperature. Avogadro's Law shows that volume or pressure is directly proportional to the number of moles of gas. Putting these together leaves us with the following equation:

P1×V1T1×n1=P2×V2T2×n2(11.9.1)

As with the other gas laws, we can also say that  (P×V)(T×n)  is equal to a constant. The constant can be evaluated provided that the gas being described is considered to be ideal.

The Ideal Gas Law is a single equation which relates the pressure, volume, temperature, and number of moles of an ideal gas. If we substitute in the variable  R  for the constant, the equation becomes:

P×VT×n=R(11.9.2)

The Ideal Gas Law is conveniently rearranged to look this way, with the multiplication signs omitted:

PV=nRT(11.9.3)

The variable  R  in the equation is called the ideal gas constant.

Mason told her he was there to get a gift for his mother. Angela wrapped up five packets of seeds, five planters, and a new weeding fork. She also put together a fresh bouquet of roses for Mason to give to his mother. When the time came to present his gift to his mother, Mason grew anxious. He didnt know whether or not she would like the gardening supplies. He wondered if he should have bought a dress like he had initially planned. Of course, it was too late to make a change, so he went to the kitchen where his mom was busy preparing a chicken dinner. Mason sneaked behind her and placed the gift on the table. He held out the bouquet and shouted, "Happy Birthday, Mama!" His mother was startled, but she accepted the bouquet with a smile. As she began to open the package, Mason could feel nervousness creeping up on him again. His mom remained silent as she removed the contents of the package.
