The two pollutants that destroys the ozone layer are CFC (Chlorofluorocarbons) and Methyl bromide. When the sun rays hit these molecules, they releases chlorine and bromine into the atmosphere. The chlorine and bromine reacts with the ozone present in the stratosphere and thus results in the depletion.
The origination of these pollutants are refrigerators, Air conditioners and aerosol cans.
Answer:
base
Explanation:
carbonic acid - H2CO3 - is a weak acid. Therefore, HCO3 itself is its conjugate base. The Na(sodium) ion is neutral.
This means that NaHCO3 is a base. (a weak one)
C I’m pretty sure. The first step is the rate determining step
0.3268 moles of PC15 can be produced from 58.0 g of Cl₂ (and excess
P4)
<h3>How to calculate moles?</h3>
The balanced chemical equation is
The mass of clorine is m(
) = 58.0 g
The amount of clorine is n() = m()/M() = 58/70.906 = 0.817 mol
The stoichiometric reaction,shows that
10 moles of yield 4 moles of 
;
0.817 of yield x moles of
n() = 4*0.817/10 = 0.3268 mol
