Answer:
both should be equal
Explanation:
it doesn't matter witch gender you are or whom is the best
Given:
AgCl (s) ===> Ag+ (aq) + Cl- (aq)
- negative entropy
H2O(g) ===> H2O(l)
- positive entropy
2Na (s) + Cl2 (g) ===> 2NaCl (s)
- positive entropy
Br2(l) ===> Br2 (s)
-positive entropy
They are identified to have positive or negative values of entropy based on the phases of the reactants and products.

The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.
Answer:
mass number = protons + neutrons.
Explanation:
Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.
