Answer:
By far the most abundant volcanic gas is water vapor, which is harmless. However, significant amounts of carbon dioxide, sulfur dioxide, hydrogen sulfide and hydrogen halides can also be emitted from volcanoes
Explanation:
A platinum wire is dipped into a strontium nitrate solution. Then inserted into a burner flame, then the strontium atoms emit a characteristic red color. this is an example of how an element can be identified by its unique atomic emission spectrum.
<h3>What is atomic emission spectrum?</h3>
The goal of an atom's electron arrangement is to keep the energy of the atom as low as feasible. An atom's ground state has the lowest energy level of all the atoms. When the energy is applied to those atoms, the electrons take it in and go to a higher energy level. The electrons in atoms have quantized energy levels, which again means that they must transition from one level to another in discrete increments rather than constantly. An atom is said to be in an excited state when its potential energy exceeds that of the ground state. An excited atom is not a stable atom.

Answer:
Decreased kinetic energy of the molecules
Explanation:
Temperature is a measure of the average kinetic energy of the molecules in a substance.
If the temperature decreases, the average kinetic energy of the molecules decreases.
A and C are wrong. Temperature has no effect on the chemical energy of molecules.
