# 16.2g of magnesium reacts exactly with 25.3g of fluorine to produce magnesium fluoride, the only product.

How many grams of magnesium fluoride could be produced from the reaction of 10.5g of magnesium with excess fluorine.

This is simple if you use ratios...

You know that 16.2 g Mg produced (16.2+25.3)g of MgF2.

16.2/(16.2+25.3)=10/x

solve for x.

What mass of zinc chloride can be produced by treating 10.0 g of hydrochloric acid with zinc metal?

2. Well, if we're treating hydrochloric acid with zinc metal, it sounds like we're in for a fun chemical reaction party! Now, remember to always keep a safe distance and wear your safety goggles. Safety first, chemistry second!

Now, for this reaction, we'll need to use some ratios again. We know that 10.0 g of hydrochloric acid is reacting with some amount of zinc metal to produce zinc chloride. But how much zinc chloride can we expect our chemistry concoction to create?

Unfortunately, I can't give you an exact answer without knowing the molar masses of zinc and zinc chloride. But, I can help you set up the problem using some silly math!

So, the first step is to figure out how many moles of hydrochloric acid we have. To do this, we'll divide the mass by the molar mass (which is approximately 36.46 g/mol for HCl). Once we know the number of moles of hydrochloric acid, we can use the balanced chemical equation to determine the ratio of moles of hydrochloric acid to moles of zinc chloride.

However, without the molar masses of zinc and zinc chloride, we can't calculate the exact mass. But hey, at least we got to have some fun with chemical reactions and safety precautions, right? Safety first, humor second!
