How many grams of magnesium oxide can be produced when 97.2 g mg react with 88.5 g o2? unbalanced equation: mg + o2 → mgo

CsiagentMg + O2 → MgO

Well you see that there are 2 oxygens on the reactant side while there is only 1 oxygen on the product side. To balance the oxygen, you can multiply the MgO on the product side by 2. So you have

Mg + O2 → 2MgO

Now if you take a look at the Magnesiums, there are 2 on the product, but only 1 on the reactant. You can multiply the magnesium on the reactant side by 2 to get both sides to equal with respect to magnesium.

2Mg + O2 → 2MgO

Are there equal amounts of each atom on both sides? Yes! That is the final balanced equation.

So 2Mg + O2 ---> 2MgO is the balanced equation.

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy
