Question

3a) Al(OH)+H,SO, =6) KOH+H.SO4 =B) Ca(OH), +H,PO,4​

Answer 1

a)2 Al(OH)3+3H2,SO4 =al2(so4)3+ 6h2o

6) 2KOH+H.SO4 =k2so4 +2h20

B) 3Ca(OH), +2H3,PO,=ca3(po4)2+6h20

Answer 2

It looks like you've provided chemical equations involving different compounds and reactants. However, there seems to be some confusion in the way you've written the equations. Chemical equations need to be balanced and written with correct chemical formulas. Let's try to clarify and balance the equations you've mentioned:

1. Aluminum hydroxide reacting with sulfuric acid: Al(OH)₃ + 3H₂SO₄ → Al₂(SO₄)₃ + 6H₂O

2. Potassium hydroxide reacting with sulfuric acid: 2KOH + H₂SO₄ → K₂SO₄ + 2H₂O

3. Calcium hydroxide reacting with phosphoric acid: 3Ca(OH)₂ + 2H₃PO₄ → Ca₃(PO₄)₂ + 6H₂O

Please note that these equations are balanced according to the conservation of mass and charge. The numbers in front of the chemical formulas represent the coefficients needed to balance the equation. Additionally, always ensure that the chemical formulas are correct and that the charges are balanced on both sides of the equation.
