How many grams of magnesium oxide can be produced when 125 g mg react with 102 g o2? unbalanced equation: mg + o2 → mgo

Balanced Equation: 2Mg + O2 ➡️ 2MgO
125 x 2= 250 102 x 2= 204
250 + 204= 454
So the answer should be 454 grams of magnesium oxide should be produced.

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom
