Use the combined gas law to calculate the "corrected" volume of hydrogen at STP
solong [7]

Answer:

We will derive the combined gas equation from the law of Gases

Boyle's law

P∝1/V

PV=Constant

Charles law

V∝T

Avogadro's Law

V∝n

By combining these three equations we get the combined gas equation

PV=nRT

V=nRT/P

If n=1 mole

V=RT/P

By putting the value of R, T, and P in the above equation we can calculate the volume of the gas at STP.

What is the chemical formula of the salt produced by the neutralization of potassium hydroxide with sulfuric acid? A. KSO3 B. K2
Lunna [17]

Answer : The correct option is, (C) K_2SO_4

Explanation :

Neutralization reaction : It is a type of chemical reaction in which an acid react with a base to give salt and water as a product that means it reacts to give a neutral solution.

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

When potassium hydroxide react with sulfuric acid then it react to give potassium sulfate (salt)and water as a product.

The balanced chemical reaction will be:

2KOH+H_2SO_4\rightarrow K_2SO_4+2H_2O

The species present on the left side of the right arrow is the reactant and the species present on the right side of the right arrow is the product.

In the balanced chemical reaction,

KOH and H_2SO_4 are reactants.

K_2SO_4 and H_2O are products.

Hence, the chemical formula of the salt produced by the neutralization of potassium hydroxide with sulfuric acid is, K_2SO_4
