hydrogen bonds. Hydrogen bonding is one of the strongest types of bonding in chemistry. A bond between hydrogen and oxygen, or hydrogen and nitrogen, or hydrogen and fluorine is required for molecules to have hydrogen bonds.</span>
6.75 moles of H₂
Explanation:
We have the following balanced chemical reaction:
Mg + 2 HCl → MgCl₂ + H₂
From the chemical reaction we deduce that if 1 mole of Mg is reating with 2 moles of HCl then 8.30 moles of Mg is reaction with 16.60 moles of HCl, quantity which is over our available 13.5 moles of HCl. The limiting reactant is HCl.
Knowing this we devise the following reasoning:
if 2 moles of HCl produces 1 mole of H₂
then 13.5 moles of HCl produces X moles of H₂
X = (13.5 × 1) / 2 = 6.75 moles of H₂

The molarity of the solution is equal to 0.500M.
<h3>Mole calculation</h3>
To calculate the molarity of a solution, one must use the value of the amount of moles and the volume, so that:
So, applying the values given in the question we have:
So, the molarity of the solution is equal to 0.500M.

false all element when they are combined eachother thier valance number will change
the combination of oxygen and aluminum gives us Al2O3 see even the numbers are changing thank you if you have a comment you can write
Cs and F
Explanation:
The two elements on the periodic table that would be most reactive would be Cesium and Florine.
Florine is the most electronegative and the most reactive non-metal on the periodic table. It has a small size and needs just one electron to complete its octet.
Cesium is the most electropositive non-metal. It requires just a loss of one electron to be stable and have complete octet.
Cs and F are the most electropositive and elecronegative elements on the periodic table of elements.
