Answer:
Temperature is not a chemical change because when a substance changes in temperature, its chemical makeup is not changing.
Answer:Number of proton present in the nucleus of an atom of sulfur is 16.
Explanation:
Protons, neutrons and electrons are subatomic particles of an atom.
Atomic number of an atom is equal to the total number of protons present in the nucleus of an atom.
Z = total number of protons
Atomic mass of an atom is defined as sum of the number of protons and neutrons present in the nucleus of an atom.
In neutral atom there are equal number of protons and electron.
A = number of proton + number of neutrons
According to question, there are 16 electrons in neutral atom of Sulfur.
in a neutral atom:
Number of electrons = Number of protons = 16
Number of proton present in the nucleus of an atom of sulfur is 16.
Answer: C. They must have the same average kinetic energy.

Explanation:
Phosphoric acid is 
and barium hydroxide is 
. Since this is an acid-base reaction, our products should be water and a salt. Put these given compounds together as the reactants:
→ 
We need to balance this by making sure there are the same number of each atom on each side of the equation. Right now, on the left, we have:
- 5 H's
- 1 P
- 6 O's
- 1 Ba
On the right, we have:
- 2 H's
- 2 P's
- 5 O's
- 3 Ba's
To balance this, add a coefficient of 2 to the H3PO4, 3 to Ba(OH)2, and 6 to H2O:
