I believe both answers are true
I believe the answer is “An atom is very small, and a model helps scientists study it.”
It’s neutral with a pH of 7. It’s probably water.
The balanced chemical reaction is:
<span>Ca + Cl2 = CaCl2
</span>
We are given the amount of calcium metal to be used for this reaction. This will be the starting point for the calculations.
56 g Ca ( 1 mol Ca / 40.08 g Ca) (1 mol Cl2 / 1 mol Ca) ( 22.414 L Cl2 / 1 mol Cl2 ) = 31.32 L Cl2 gas produced from the reaction
Protons: 12
Neutrons: 13
<span>Electrons: 12</span>
