Question

Получить 8-ю разными способами сульфат бария: 1) основный оксид + кислотный оксид 2) основный оксид + кислота 3) основание + кислотный оксид 4)основание + кислота 5)соль + кислота 6)металл + кислота 7)соль + соль 8)основание + соль

Answer 1

1) BaO + SO3 = BaSO4
2) BaO +H2SO4 = BaSO4 +H2O
3) Ba(OH)2 +SO3 = BaSO4 +H2O
4) Ba(OH)2 +H2SO4 = BaSO4 +2H2O
5) BaCl2 + H2SO4 = BaSO4 +2HCl
6) Ba + H2SO4 = BaSO4 +H2
7) BaCl2 + K2SO4 = BaSO4 +2KCl
8) Ba(OH)2 + Na2SO4 = BaSO4 +2NaOH

Answer 2

Obtaining Barium Sulfate in 8 Different Ways

1) Basic Oxide + Acidic Oxide: - Barium oxide (BaO) is a basic oxide, and sulfur trioxide (SO3) is an acidic oxide. When combined, they form barium sulfate (BaSO4) as a salt. 2) Basic Oxide + Acid: - Barium oxide (BaO) can react with sulfuric acid (H2SO4) to produce barium sulfate (BaSO4) and water (H2O). 3) Base + Acidic Oxide: - Barium hydroxide (Ba(OH)2) is a base, and sulfur trioxide (SO3) is an acidic oxide. Their reaction yields barium sulfate (BaSO4). 4) Base + Acid: - Barium hydroxide (Ba(OH)2) can neutralize sulfuric acid (H2SO4) to form barium sulfate (BaSO4) and water (H2O). 5) Salt + Acid: - Barium chloride (BaCl2) is a salt that can react with sulfuric acid (H2SO4) to produce barium sulfate (BaSO4) and hydrochloric acid (HCl). 6) Metal + Acid: - Barium, as a metal, can react with sulfuric acid (H2SO4) to form barium sulfate (BaSO4) and hydrogen gas (H2). 7) Salt + Salt: - Barium chloride (BaCl2) can also react with sodium sulfate (Na2SO4) to yield barium sulfate (BaSO4) and sodium chloride (NaCl). 8) Base + Salt: - Barium hydroxide (Ba(OH)2) can react with sulfuric acid (H2SO4) to produce barium sulfate (BaSO4) and water (H2O), which can be considered as a reaction between a base and a salt.
