Question

Указать реакцию расклада: Ca + HCl = CaCl2 + H2 = Ca + 2HCl = CaCl2 + H2 N2 + O2 = NO = N2 + O2 = 2NO Al(OH)3 = Al2O3 + H2O = 2Al(OH)3 = Al2O3 + 3H2O

Answer 1

2Al(OH)3 (t)= Al2O3 + 3H2O

Answer 2

Sure, let's balance the chemical equations for the given reactions:

1. Ca + 2HCl = CaCl2 + H2

2. N2 + 2O2 = 2NO

3. 2Al(OH)3 = Al2O3 + 3H2O

Explanation:

1. Calcium (Ca) reacts with hydrochloric acid (HCl) to form calcium chloride (CaCl2) and hydrogen gas (H2).

2. Nitrogen gas (N2) reacts with oxygen gas (O2) to form nitric oxide (NO).

3. Aluminum hydroxide (Al(OH)3) decomposes to form aluminum oxide (Al2O3) and water (H2O).

Note: The first two equations are balanced, but the third equation is not fully balanced. The balanced equation for the third reaction is:

2Al(OH)3 = Al2O3 + 3H2O
