The maximum volume of hydrogen evolved at room temperature and prressure after taking excess zinc with 0.01 mol HCl is 2.4 
hence correct option is (C)
<h3>What is Ideal gas law ?</h3>
According to this law, the product of the pressure and the volume of one gram molecule of an ideal gas is equal to the product of the absolute temperature of the gas and the universal gas constant.
Given Equation ;
Zn + 2HCl --> 
+ 
Given Quantities ;
Amount of Zinc = Excess
Amount of 1.0 mol/ltr HCl = 100 ml
It means, Number of moles of H = 0.1 mole
Temperature = 298 K
Pressure = 1 Atm
This is a “single state” problem, so we can solve it using the ideal gas law, PV = nRT.
therefore, using Ideal gas equation ;
PV=nRT
1 x V = 0.1 x 0.0821 x 298
volume of hydrogen gas = 2.4 litre ie, 2.4

Your answer is. C. CI2(g)+H2(g)
Answer:
Explanation:
¡Hola!
En este caso, teniendo en cuenta la información dada por el problema, inferimos que primero se debe usar la ecuación del gas ideal con el fin de calcular las moles de gas que se encuentran al inicio del experimento:
Seguidamente, usamos la ley de Avogadro para calcular las moles finales, teniendo el cuenta que el volumen final es el doble del inicial (8.50 L):
Quiere decir que las moles de N2(g) que se agregaron son:
