magnesium is a highly flammable element which is easily combustible in the presence of oxygen: 2mg + o₂ -> ?? + heat. how many atoms would you expect to find on the product side of this equation? a 1 b 2 c 3 d 4

Answer

Explanation:

Step1: Balance the chemical equation

The balanced equation for the combustion of magnesium in oxygen is $2Mg + O_2\rightarrow 2MgO$.

Step2: Count atoms in products

In $2MgO$, there are 2 magnesium (Mg) atoms and 2 oxygen (O) atoms. So in total, there are $2 + 2=4$ atoms.
