DOL: Gas Laws
At equilibrium, what is the partial pressure of hydrogen collected over water in a flask at an atmospheric pressure of 740.2 mmHg if the
water's partial pressure is 19.8 mmHg?
А
20.3 mmHg
B
37.4 mmHg
c с
720.4 mmHg
D
760.0 mmHg

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.

pie chart because it is in percents ( % )

fe 55.85 g/mol and h2o 18.02 g/mol.
