Answer: 52.17%
Explanation:
Number of matches in the box = 46
Number of matches that lit on the first strike = 22
Number of matches that did not light on the first strike = 46 - 22 = 24
Therefore, the percentage of the matches in the box did not light on the first strike will be:
= (Number of matches that did not light on the first strike / Number of matches in the box) × 100
= 24/46 × 100
= 52.17%
Therefore, the percentage of the matches in the box that did not light on the first strike is 52.17%.
magnesium oxide is: MgO (right side)
so the left side is: Mg + O2
for the equation to be balanced there must be two oxygens on both sides
Mg + O2 = 2MgO
but now the magnesium is uneven, so there must be two magnesiums on each side
the answer is: B) 2Mg + O2 = 2MgO
