Answer:

3Mg + Fe2O3 = 2Fe + 3MgO

Explanation:

Make sure the number of each element equal on both right and left hand side

Eg. There are 3 molecules of oxygen on left hand side so to balance right hand side add a 3 in front of MgO, because you've added a 3 in front of MgO you now have to add a 3 in front of Mg on the left hand side to balance it out and continue to do so for the rest of the chemical equation.

Note the mass of copper(1) oxide formula unit 143.091 what is the mass of 8.250 moles of Cu2O
baherus [9]

Answer:

The mass of 8.250 moles of Cu2O is 1180.5g

Explanation:

HOW TO CALCULATE MASS OF A SUBSTANCE:

  • The mass of a substance can be calculated by multiplying the number of moles in the substance by its molar mass as follows:

Mass (g) = no. of moles (mol) × molar mass (g/mol)

  • Molar mass of copper (I) oxide (Cu2O) = 63.5(2) + 16 = 143.09 g/mol

Mass of Cu2O = 8.250 mol × 143.09 g/mol

Mass of Cu2O = 1180.5 g

Therefore, the mass of 8.250 moles of Cu2O is 1180.5 g.
