The size of the container needed to hold the gas is 1.03 L
The volume of the container needed can obtained by using the ideal gas equation as illustrated below:
PV = nRT
Divide both side by P
V = nRT / p
V = (0.0459 × 0.0821 × 273) / 1
V = 1.03 L
Therefore, the size of the container needed is 1.03 L.

Answer:
The size of the container needed is 1,03 liters
Explanation:
We use the formula PV=nRT. The STP conditions correspond to 1 atm of pressure and 273 K of temperature.
PV=nRT V=(nRT)/P
V= (0,0459 mol x 0,082 l atm/ K mol x 273K)/1 atm= 1,0275174 liters
Answer:
Classify each of the following statements as an experiment, a hypothesis, a scientific law, an observation, or a theory.
(1) For example, Joseph Gay-Lussac reacted hydrogen and oxygen to produce water vapor, and he reacted nitrogen and oxygen to form either dinitrogen oxide (N2O) or nitrogen monoxide (NO). Gay-Lussac found that hydrogen and oxygen react in a 2:1 volume ratio and that nitrogen and oxygen can react in 2:1 or 1:1 volume ratios depending on the product.
(2) In 1808, Gay-Lussac published a paper in which he stated that the relative volumes of gases in a chemical reaction are present in the ratio of small integers provided that all gases are measured at the same temperature and pressure.
(3) In 1811, Amedeo Avogadro proposed that equal volumes of all gases measured at the same temperature and pressure contain the same number of molecules.
(4) By midcentury, Rudolf Clausius, James Clerk Maxwell, and others had developed a detailed rationalization of the behavior of gases in terms of molecular motions
The correct answers to the question are as follows
(1) An experiment
(2) A scientific law
(3) A hypothesis
(4) A theory
Explanation:
(1) An experiment
A scientific experiment involves the development of procedures to verify an hypothesis
(2) A scientific law
A scientific law is a description or general rule to explain an observed phenomenon using a mathematical or verbal statement without attempting to provide an explanation
(3) A hypothesis
An hypothesis is an explanation of an observed phenomenon which can then be tested through the performance of experiments
(4) A theory
A theory in science is an explanation of naturally occurring phenomenon backed up by the results of experiments and observation
The given statements have been classified as experiment (1), observation (2), scientific law statement (3), hypothesis (4), and theory (5) respectively in the context of Chemistry.
1. Joseph Gay-Lussac reacted hydrogen and oxygen to produce water vapor, and he reacted nitrogen and oxygen to form either dinitrogen oxide or nitrogen monoxide: This is an experiment.
2. Gay-Lussac found that hydrogen and oxygen react in a 2:1 volume ratio and that nitrogen and oxygen can react in 2:1 or 1:1 volume ratios depending on the product: This is an observation.
3. In 1808, Gay-Lussac published a paper in which he stated that the relative volumes of gases in a chemical reaction are present in the ratio of small integers provided that all gases are measured at the same temperature and pressure: This is a statement of a scientific law.
4. In 1811, Amedeo Avogadro proposed that equal volumes of all gases measured at the same temperature and pressure contain the same number of molecules: This is a hypothesis.
5. By midcentury, Rudolf Clausius, James Clerk Maxwell, and others had developed a detailed rationalization of the behavior of gases in terms of molecular motions: This is a theory.

The plausible reason for the change in mineral A will be the lower activation energy than the transferred energy.
The addition of energy will result in the change in the minerals if the activation energy is exceeded.
The minerals found in mining A and B have transferred the energy. The minimum amount of energy required to do the transition in the atoms in the activation energy.
The possible reason for the change in the mineral A will be the lower activation energy for the mineral A. The mineral B does not change because the activation energy of mineral B is higher as compared to mineral A.
For more information, refer to the link:
Answer: Mineral A changed because Molecular energy transferred is equal or greater than than its Activation energy
Mineral B didn't change because Molecular energy transferred is less than its Activation energy.
Explanation:
The molecules of Mineral A has been disturbed by the addition of energy causing a change and the entropy is increased. The Molecules of Mineral B has not been disturbed because the residual energy has not been overcome and therefore yielding no visible change
FALSE
This is an example of negative mutation. Negative mutations produce a phenotype that acts antagonistically to the wild-type phenotype. On the other hand positive mutation produce a phenotype that acts synergistically to the wild-type phenotype.
The negative mutation will negatively affect the long term survival of the butterfly species as the mutation makes the new butterfly offsprings more visible to predators.
