Mrs. Moran and Mr. Moran decided to move the cabinet in their dining room. Mrs.
Moran stood on one side, and Mr. Moran stood on the other. They each pushed
with 30 N of force. What was the net force on the cabinet?
Answer:
60N
Explanation:
The net force on the cabinet is 60N.
Net force is that single force that will act like all other forces on a body. The direction of the force and magnitude is very important when resolving forces.
Force applied by Mrs. Moran = 30N
Force applied by Mr. Moran = 30N
Since they each stood on both sides and pushed, the net force will be 30N + 30N = 60N
Answer: 0
Explanation: If they both pushed a force of 30N then it doesn’t add up but instead you subtract. so it’s 0. ur yw ;)

please show the work :(What is the estimated force applied to the box if the acceleration is .40 m/s2?
force (N) acceleration (m/s2)
10 .20
? .40
Answer:
20N
Explanation:
Given parameters:
Force(N) Acceleration(m/s²)
10 0.2
? 0.4
Unknown:
The force applied when the acceleration is 0.4m/s²
Solution:
From newton's second law of motion;
Force = mass x acceleration
Since we are using the same box, let us find the mass of the box;
Force = mass x acceleration
10 = mass x 0.2
mass = [tex]\frac{10}{0.2}[/tex] = 50kg
Now,
The force in the second instance will be;
Force = 50 x 0.4 = 20N

Ayala is making salad dressing. She mixes oil and
vinegar in a blender until a smooth consistency is
formed. Explain whether this is a heterogeneous or a
homogeneous mixture and why.
Answer:
A heterogeneous mixture
Explanation:
A heterogeneous mixture is a mixture that is not uniform in composition. This means that we can tell that there is more than one component in the mixture. An example of a heterogeneous mixture would be milk and cereal.
The opposite is a homogeneous mixture, which is uniform in composition. An example of a homogeneous mixture is air. There are many different particles surrounding us, but we can't tell.
A salad dressing that consists of oil and vinegar is another example of a heterogeneous mixture. Its consistency is smooth, but oil and vinegar can't dissolve each other, which means that we will see droplets of oil and vinegar. Since we can tell that it contains these components, this is a heterogeneous mixture.
Answer:
Sample Response: A homogeneous mixture can only form when one of the substances can dissolve the other one. Oil and water cannot dissolve each other, so they must form a heterogeneous mixture with small particles of vinegar dispersed throughout the oil, yet not dissolved.

What is the mass of HF produced by three reaction of 3.0 10 to the 23 molecules of H2 with excess F2
Answer:
It is 20. g HF
Explanation:
H2 + F2 ==> 2HF ... balanced equation
Since the question is asking us to find the mass of product formed, we will want to first convert the molecules of H2 into moles of H2 (we could do this at the end of the calculations, but it's just as easy to do it now).
moles of H2 present (using Avogadro's number):
3.0x1023 molecules H2 x 1 mole H2/6.02x1023 molecules = 0.498 moles H2
From the balanced equation, we see that 1 mole H2 produces 2 moles HF. Therefore, we can now find the theoretical mass of HF produced from 0.498 moles H2:
0.498 moles H2 x 2 moles HF/1 mol H2 = 0.996 moles HF formed.
The molar mass of HF = 20.01 g/mole, thus...
0.996 moles HF x 20.01 g/mole = 19.93 g HF = 20. g HF formed (to 2 significant figures)

Which ion has smaller size and why?Mg++ or Na+.
Answer:
Explain your answer. mg2+ would be the smaller ion this is because each ion has the same number of electrons however mg2+ has a greater number of protons and therefore is more charge dense and the outer electrons feel a greater pull from the nucleus.

El plomo y el yodo forman dos compuestos. En uno, el porcentaje de en masa de plomo es del 44,94% y en el otro es de 62,02%. Calcula los gramos de plomo por gramos de yodo en cada compuesto
Answer:
0.8162 gramos de plomo por gramo de yodo
1.633 gramos de plomo por gramo de yodo
Explanation:
Asumiendo una base de 100 gramos para cada compuesto:
Primer compuesto:
Gramos plomo: 44.94g
Gramos de yodo: 100-44.94g = 55.06g
Así, la masa de plomo por gramos de yodo para el primer compuesto es:
44.94g plomo / 55.06g Yodo =
0.8162 gramos de plomo por gramo de yodo
Segundo compuesto:
Gramos plomo: 62.02g
Gramos de yodo: 100-62.02g = 37.98g
La masa de plomo por gramos de yodo para el segundo compuesto es:
62.02g plomo / 37.98g Yodo =
1.633 gramos de plomo por gramo de yodo
Sucrose is an organic compound made by plants for quick energy. What type of organic compound is sucrose?
1-protein
2-carbohydrate
3-lipid
4-nucleic acid
Answer:
2-carbohydrate
Explanation:
Sucrose belongs to the carbohydrate family. It is a disaccharide which is derived from the condensation of glucose and fructose.
In the body, they are sources of energy for living processes. Upon hydrolysis such disaccharide produces tow monosaccharide units. Food substances that are energy rich will contain some of these organic molecules.Sucrose is a specific type of organic compound classified as a carbohydrate and the correct option is option 2.
Carbohydrates are essential biomolecules made up of carbon, hydrogen, and oxygen atoms. Sucrose, also known as table sugar, is a disaccharide formed by the chemical bonding of one glucose molecule and one fructose molecule.
Plants produce sucrose through photosynthesis and use it as a readily available source of energy. When consumed by animals, including humans, sucrose is broken down into its constituent monosaccharides to provide fuel for various cellular processes.
Thus, the ideal selection is option 2.

Why do atoms form bonds with other atoms?
SELECT ALL THAT APPLY
a
To ensure that both atoms in the bond have eight total
electrons.
b To obey the octet rule.
С
To fill the outer electron shells of both atoms.
d
To achieve a more stable electron configuration for both
atoms.
The smallest unit that combines chemically or physically to form molecules and compounds is called an atom. They are composed of electrons and protons and neutrons in the nucleus.
The correct answer is:
Option d. To achieve a more stable electron configuration for both atoms.
This can be explained as:
Atoms do not always bond to complete eight electrons in their shells.Atoms do not react to follow the octet rule.Electrons don't need to be filled in the shells of atoms of both the shells as some atoms lose electrons too.Therefore to achieve stable configuration atoms bond with other atoms.

Law of conservation of mass and energy are related as mass and energy are directly proportional which is indicated by the equation E=mc².Concept of conservation of mass is widely used in field of chemistry, fluid dynamics.
Law needs to be modified in accordance with laws of quantum mechanics under the principle of mass and energy equivalence.This law was proposed by Antoine Lavoisier in the year 1789.
