The NH3 sample that will fill and take the shape of a 100.0-milliliter container is NH3(g). Gases such as NH3(g) expand to fill their container, as explained by the ideal gas law and Avogadro's law.
To answer your question about NH3, we need to consider each of the states of matter. Hence, the answer is (3) NH3(g). This is because of the properties that gases have, including the ability to fully expand and take the shape of their container regardless of the volume of the container.
Specifically, any gaseous substance, such as NH3(g), expands to fill its container due to the kinetic energy of the gas molecules and their relatively far-apart spacing compared to solids and liquids. Even a small amount of gas can completely fill even a relatively large container. This phenomenon is due to one of the main gas laws, the ideal gas law, and the properties of gases as stipulated by Avogadro's law that equal volumes of gaseous N₂, H₂, and NH3, at the same temperature and pressure, contain the same number of molecules.
This concept is fundamental in the stoichiometry of gaseous substances and Dalton's law of partial pressures, which states that the total pressure exerted by a mixture of gases is equal to the sum of the pressures that each would exert if it were present alone and occupied the same volume.

The answer is: A) Yes, because the question is specific.
The scientific method is a process for experimentation that is used to explore observations (in this example color of snowshoe hares).
Steps of the scientific method:
1) ask a question about something that is observed.
2) do background research.
3) construct a hypothesis, an attempt to answer questions with an explanation that can be tested.
4) test of hypothesis.
5) analyze collected data and draw a conclusion.
The two main variables in an experiment are the independent and dependent variable.
Dependent variable is the variable being tested and measured in a scientific experiment, in this example lifespan of snowshoe hares.
Dependent variables depend on the values of independent variables. The dependent variables represent the output or outcome whose variation is being studied.
b. Catalysts are always formed by chemical reactions.
c. Catalysts are used up during a chemical reaction.
d. Catalysts lower the activation energy of a chemical reaction

In 1 lb there are 450 grams (Rounded upto 2 - Significant figures).
We havea weight gain of 1.0 lb.
We have to convert it into grams.
I lb = 453.592 grams
According to the question -
A = 1 lb
Converting it into grams, we get -
1 lb = 1 x 453,592 = 453.592 grams
Rounding up to 2 - Significant figures, we get -
1 lb = 450 grams
Hence, in 1 lb there are 450 grams (Rounded upto 2 - Significant figures).

The highly reactive gas that was probably absent from the Earth's primitive atmosphere is oxygen.
The atmosphere refers to the thin layer of gas above the earth's crust. This thin layer of gases is composed of a mixture of gases. The earth's primitive form also had an atmosphere.
However, we must recall that in its primitive form the earth was mostly under reducing conditions and there was no oxygen. However, photosynthesis by plants increased the oxygen content of the earth.

B. decomposition
C. double-replacement reaction
D. synthesis
Answer: Option (C) is the correct answer.
Explanation:
It is given that when an acid and a base form a salt and water.
For example,
Therefore, in this type of reactions there is exchange of ions between the two compounds hence, it is known as double-displacement reaction.
Thus, we can conclude that out of the given options the term an acid and a base form a salt and water describes an acid-base reaction.
