This problem can be solved by using oxidation states. The oxidation state is based on the electrons an atom loses or gain, or appears to use when forming compounds.To find the formula for Copper (I) Sulfide, we have to first consider the individual ions that come together to form it. Copper (I) is an ion of copper that has a charge of +1, i.e 
. Sulfur is an element in group 6 of the periodic table. The sulfur ion has a charge of -2, i.e 
. To form Copper (I) Sulfide, which is electrically neutral, we need 2 Copper (I) ions and 1 sulfur ion.
.
The reaction is represented by the equation below
.
The correct answer is (C)

Explanation:
(a)
- Oxygen consumption rate of humans,
area of human skin, 
- diffusion rate through skin of humans,
- ∴
<u>Flux of diffusion rate, </u>

The smooth muscle in the wall of the bladder when stretched triggers the micturition reflex (urination).
<h3>What is a Bladder?</h3>
This is defined as a lined layers of muscle tissue that stretch to hold urine in organisms.
In older people the elasticity of the bladder is reduced which is why it makes it harder for them to hold urine for a long time.
