Consider the balanced equation below.
2H2S + 302 - 2502 + 2H2O
Which option gives the correct mole ratios?
HQS SO2 = 2.2 and O2: H2O = 3.2
H2S SO2 = 2.3 and O2 H2O = 3.2
H2S SO2 = 4.4 and O2: H2O = 5.4
H2S SO2 = 4:6 and 02:H2O = 4:4

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

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 !

you need to stop taking that class
