Is this equation violating the law of conservation of mass? Explain why. 3 H2SO4 + 2 Fe(OH)3 -->Fe2(SO4)3 + 4 H2O

Group of answer choices
No; There is an equal amount of each type of element
Yes; There is an equal amount of each type of element
Yes; H is being destroyed when the products formed
No; H is being destroyed when the products formed

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
