H2SO4 + Ba(OH)2à BaSO4 + H2O is an unbalanced chemical equation. What is the coefficient for sulfuric acid (H2SO4) when this equ
2 answers:
Answer: Coefficient for sulphuric acid is 1.
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
When an acid reacts with the base then it undergoes neutralization to form a salt and water.
The balanced reaction will be,
Thus coefficient for sulphuric acid is 1.

Answer : The volume of gas occupy at is, 1.25 L
Explanation :
Charles' Law : It states that volume of the gas is directly proportional to the temperature of the gas at constant pressure and number of moles.
Mathematically,
where,
are the initial volume and temperature of the gas.
are the final volume and temperature of the gas.
We are given:
Putting values in above equation, we get:
Therefore, the volume of gas occupy at is, 1.25 L
