AnnZ [28]

According to the principle of chemical equilibrium, when additional hypochlorous acid is added, the hypochlorite ion concentration will increase.

<h3>What is chemical equilibrium?</h3>

Chemical equilibrium refers to the equilibrium which exists between chemical species in a reaction such that the rate of forward and backward reactions are the same.

Since the reaction is in equilibrium, when additional hypochlorous acid is added, the hypochlorite ion concentration will increase ad equilibriumwill shift to the right of the reaction.

HELP ASAP!!!
Paraphin [41]
Solution..
---------------

Let's calculate the mass of CO₂.

We have (12+(16*2))
= 12+32
=44gmol¯¹..

a. What is the percent by mass of carbon?

Mass of carbon /mass of CO₂ × 100%

12/44 × 100%

=27.3%...

b. What is the percent by mass of oxygen?

Mass of oxygen/mass of CO₂ × 100%

(2×16)/44 × 100%

32/44 × 100%

=72.7%....

To check.. You'll add this two percentage compositions together and see of it gives 100%... If it does then we're good...

27.3%+72.7% = 100%.... Checked..

Hope this helped....?
