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.
