7. Write the balanced equation for the equation for the reaction of magnesium with HCl. What is the mole ratio between magnesium and magnesium chloride will be produced? If 2.5g of magnesium react, how many moles of magnesium chloride will be produced? How many grams of magnesium chloride will be produced?

4 answers

Mg + 2HCl ==> MgCl2 + H2

1. Convert 2.5 g Mg to moles. # moles = grams/molar mass.
2. Using the coefficieints in the balanced equation, convert moles Mg to moles MgCl2.
3. Convert moles MgCl2 to grams. # grams = moles x molar mass.
