A container is filled with a mixture of carbon dioxide oxygen and nitrogen gas is the total pressure inside the container is 1.5 ATM if the pressure of the carbon dioxide gas is 0.16 ATM and the pressure of the oxygen gas is .45 ATM then what is the partial pressure of the nitrogen gas in atmospheres please show work

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 !

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.

i think that the answer is c
