Balanced Equation: H2SO4 + 2NaOH --> 2H2O + Na2SO4
Moles= Mass/RMM
= 65.5/40
= 1.6375
Mole Ratio = 2:2
= 1.6375
Mass (H2O) = 1.64 x 18
= 29.5 g
Answer:
I don't know that anwser sorry
The half reactions as they occur at each electrode
is as follows
at the anode Sn(s) =sn^2+(aq) + 2e -
at the cathode 2 ag^+(aq) + 2e - = 2Ag (s)
net cell reaction = Sn (s) + 2Ag^+(aq) = sn^2+ (aq) + 2 Ag (s)
Most transition metal form more than one cation but aluminum forms the Al3+ cation only.
The balanced chemical reaction is:

To determine the mass of hydrogen that is needed, we need use the initial amount of oxygen and relate it to hydrogen from the reaction given. We do as follows:
192 g O2 ( 1 mol O2 / 32 g O2) ( 2 mol H2 / 1 mol O2 ) ( 2.02 g H2 / 1 mol H2 ) = 24.24 g H2
