Answer:
cfcl3
Explanation:
When the cfcl3 in the atmosphere is hit by UV rays from the sun, it decomposes to Cl atoms. These Cl atoms then react with the ozone producing O2 and ClO. The ClO bombard with O atoms splitting the ClO up and the free Cl atom again bonds to another O3 molecule hence reducing it. One ClO can reduce several O3 molecules (up to 100,000) creating an ozone hole.
2Cl + O3 → 2ClO + 2O2
2ClO + 2O → 2Cl + 2O2
Answer:
The term submersible is often used to differentiate from other underwater vessels known as submarines, in that a submarine is a fully autonomous craft.

Explanation:
Answer: -
81.03 g magnesium oxide is formed when 48.62g of magnesium is reacted with excess oxygen
Explanation: -
Atomic mass of Mg = 24 g
Molar mass of MgO = 24 x 1 + 16 x 1
= 40 g
The balanced chemical equation for this reaction is
2 Mg + O₂ → 2MgO
From the balanced chemical equation we see
2 mol of Mg gives 2 mol of MgO.
2 x 24 g of Mg gives 2 x 40g of MgO.
48.62 g of Mg gives
x Mg
= 81.03g of MgO
