suppose 2.4 g of mg reacts with 10.0 g of o2, to create magnesium oxide. how much magnesium oxide is produced?

3.98 g

Explanation:

Step 1. Write the balanced chemical reaction. In this case, magnesium reacts with oxygen to produce magnesium oxide:

\\

Step 2. Calculate the number of moles of magnesium:

\\

Step 3. Calculate the number of moles of oxygen:

\\

Step 4. Identify the limiting reactant comparing the equivalents. Equivalent of Mg:

Equivalent of oxygen:

Therefore, Mg is the limiting reactant.

\\

Step 5. According to the stoichiometry of this reaction:

\\

Step 6. Convert the number of moles of MgO into mass:

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
