Question

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?

Answer 1

Answer: 2 atoms of MgO will be there on the product side.

Step-by-step explanation: We are given an element Magnesium which is highly flammable and when reacted with oxygen will follow equation:

`2Mg(s)+O_2(g)\rightarrow 2MgO(s)+heat`

By Stoichiometry,

2 moles of magnesium solid reacts with 1 mole of oxygen gas to produce 2 moles of magnesium oxide solid which is white in color with the release of heat.

At the product side, 2 atoms of magnesium oxide will be present.

Answer 2

The number of atoms would expect to find on the product side of the reaction between Mg and O₂ is 4 atoms

Explanation

Mg react with O₂ to produce MgO according to reaction below

2Mg +O₂ →2 MgO +heat

MgO is the product ,therefore the number of atoms in product side is

= 2 [ atoms of Mg + atoms of O]

= 2[ 1+1] = 4 atoms
