What is the hydrogen ion concentration [H+] in a 3.76 x 10^-2 M solution of nitric acid (HNO3)

1 answer:

8 0

Nitric acid (HNO₃) is a strong acid. Hence, it completely dissociates into ions as H⁺ and NO₃⁻ in water.

The balanced equation is;

HNO₃(aq) →H⁺(aq) + NO₃⁻(aq)

The stoichiometric ration between HNO₃(aq) and H⁺(aq) is 1 : 1

Hence, the [H⁺] = 3.76 x 10⁻² M

What is the measure of force per unit area.

Brut [27]

Pressure

Explanation:

Pressure is a measure of force per unit area.

Pressure is defined as the force exerted on a body across a unit area. The unit of pressure is N/m² or Pascal.

Pressure = $\frac{Force}{Area}$

The more the force acting on a body the more the pressure felt. A small surface area and a large force increases pressure on a body.

it is right to say that pressure is proportional to force but inversely proportional to area.

What adaptation do lungfish have te help them walk and live on land?

Viktor [21]

Answer: biological adaptation

Explanation:

lungfish's lung is a biological adaptation. A biological adaptation is a physical change in an organism that develops over time. Like all fish, lungfish have organs known as gills to extract oxygen from water. The biological adaptation of the lung allows lungfish to also extract oxygen from the air.

I hope this helps :).
