Call

n(NaOH) = 3.50 moles

Solution:

The equation of a chemical reaction:

2NaOH + H2SO4 --> Na2SO4 + 2H2O

According to the chemical equation: n(NaOH)/2 = n(Na2SO4).

n(Na2SO4) = n(NaOH)/2;

n(Na2SO4) = 3.50 moles / 2 = 1.75 moles.

n(Na2SO4) = 1.75 moles.

Answer: 1.75 moles of Na2SO4.

Write equilibrium expression for the following reactants (reactants and products are all gases): (a) N3 + 3H2⇌2NH3 (b) 4HCl + O2⇌2H2O (c) CH4 + 2O2⇌CO2 + 2H2O (d) 3C2H2⇌C6H6 (e) 2CO2⇌2CO + O2

According to the equilibrium expression:aA + bB = cC + dDKeq = [C]c[D]d / [A]a[B]bFrom here:(a) Keq = [NH3]2 / [N3][H2]3(b) Keq = [H2O]2 / [HCl]4[O2](c) Keq = [CO2][H2O]2 /...

Is H3PO4 a triprotic or diprotic acid, if it is a trprotic acid, then how do we explain its reaction with sodium hydroxide? i.e. H3PO4 + 2NaOH == Na2HPO4 + 2H2O.

H3PO4 is a trprotic acid,but the reactivity of cleavage ща proton determine the dissociation constant. For the third proton is much smaller than for the second and first H3PO4(s) +...

2NaOH+H2SO4 - 2H2O+Na2SO4 how many grams of sodium sulfate will be formed if you start with 250 grams of sodium hydroxide and you have an excess of sulfuric acid?

First we must calculate the mole for NaOH. n(NaOH)=250/40= 6.25 moles of NaOH. From reaction we see than 2 moles of NaOH give 1 mole of Na2SO4. That means, that...
