Which laws can be combined to form the ideal gas law? boyle’s law and charles’s law gay-lussac’s law and avogadro’s law charles’s law, avogadro’s law, and boyle’s law dalton’s law, gay-lussac’s law, and avogadro’s law

Charles’s law, Avogadro’s law, and Boyle’s law

Explanation:-

1. Charles' Law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.

   (At constant pressure and number of moles)

2. Avogadro's Law states that volume is directly proportional to the number of moles of the gas at constant pressure and temperature.

       (At constant temperature and pressure)

3. Boyle's Law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.

    (At constant temperature and number of moles)

Combining all three we get, ideal equation:

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
