The reaction equation is the chemical formula of reagents and product substances
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products
Reaction
2 Al (s) + 6 HCl (aq) → 2 AlCl₃ (aq) + 3 H₂ (g)
mol Al :

mol H₂ :

At STP, 1 mol =22.4 L
so the volume of hydrogen :

Answer:
a. The number of neutrons in the nucleus
Explanation:
Having more protons or electrons would change the charge of the atom making it an ion. Neutrons have no charge so the overall charge of the atom is not affected; neutrons also have a relative mass of 1 which is why there are different isotopes.
Hope this helps!
I found the grams per mole values based off of the atomic mass of iodine and Magnesium
The population will get low because the food we eat is animals which is species then the animals that eat that prey will die off because that might be there only prey....then if more species is gone there will be nothing left
I Hope this helped
