URGENT PLEASE HELP Sulfuric Acid, H2SO4, can me neutralized be sodium hydroxide, NaOH.

The unbalanced equation is : H2SO4(aq) + NaOH(aq) -> Na2SO4(aq) + H2O(I)

a student who was asked to balance the reaction wrote the following: H2SO4(aq) + Na2OH(aq) -> Na2SO4(aq) + H3O(I)

is this correct? explain why or why not using what you know about the law of conservation of mass and chemical changes. provide the correct balanced equation.

i'm pretty sure it is letter c.) car

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2

answer: mole of the gas

answer: mole of the gasexplanation:
