1. When a gas is heated,
A all of the absorbed energy is converted to kinetic energy
O
B
none of the energy is converted to kinetic energy
Csome of the absorbed energy is converted to potential energy and
some is converted to kinetic energy
D all of the absorbed energy is converted to potential energy

The correct option is C. Some of the absorbed energy is converted to potential energy and some is converted to kinetic energy

Explanation:

Thus by considering this above explanation it is clear that Option C can be consider as the opt answer

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2
