Answer is A) Al4C3 + 3H2O -> CH4 + 4Al(OH)3

One the left side there are 3 carbon atoms, or moles of carbon, and on the write side there is only one.

In order to solve these problems, count the number of atoms on each side and make sure that for each element, the number of atoms are equal.

For example, for the last problem, we have 1 zinc atom on each sidde, two hydrogen atoms, and two chlorine atoms.

Sulfuric acid reacts with aluminum hydroxide by double replacement. if 34 g of sulfuric acid react with 33 g of aluminum hydroxi

Lina20 [59]

Answer is: sulfuric acid is the limiting reactant.
Chemical reaction: 3H₂SO₄ + 2Al(OH)₃ → Al₂(SO₄)₃ + 6H₂O.
m(H₂SO₄) = 34 g.
n(H₂SO₄) = m(H₂SO₄) ÷ M(H₂SO₄).
n(H₂SO₄) = 34 g ÷ 98 g/mol.
n(H₂SO₄) = 0,346 mol.
m(Al(OH)₃) = 33 g.
n(Al(OH)₃) = 33 g ÷ 78 g/mol.
n(Al(OH)₃) = 0,423 mol.
From chemical reaction: n(H₂SO₄) : n(Al(OH)₃) = 3 : 2.
