Answer:Volume occupied by the gas at standard pressure is 162.5 L.
Explanation:
Pressure of the gas when it occupies volume of 190 L = 650 mmHg
Volume occupied by the gas when the gas is at standard pressure.
The value of standard pressure = 1 atm = 760 mmHg
According to Boyle's Law: 
(at constant temperature)
Volume occupied by the gas at standard pressure is 162.5 L.
This act is called adhesion: the process of water, sticking onto other substances.

Explanation:
Answer: The coefficients are 2, 2 and 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.
The balanced chemical equation for the given reaction is:
2H2o➡️2h2+o2
