when ch3cooh, nahco3 and as2o3 is heated ,what product will be formed?
When heated:
1. acetic acid
phase change
2. sodium bicarbonate
decomposition into sodium carbonate, carbon dioxide and water.
3. arsenic trioxide
phase change
To determine the products formed when ch3cooh (acetic acid), nahco3 (sodium bicarbonate), and as2o3 (arsenic trioxide) are heated, we need to consider the chemical reactions that can potentially occur.
1. Acetic acid (ch3cooh) can undergo a thermal decomposition reaction:
2ch3cooh ⟶ 2ch3cooCH3 + h2o
2. Sodium bicarbonate (nahco3) can undergo a thermal decomposition reaction as well:
2nahco3 ⟶ na2co3 + co2 + h2o
3. Arsenic trioxide (as2o3) can also undergo a thermal decomposition reaction:
2as2o3 ⟶ 4as + 3o2
By examining these reactions, we can determine the products formed when each substance is heated:
- When acetic acid (ch3cooh) is heated, it decomposes into acetic anhydride (ch3cooCH3) and water (h2o).
- When sodium bicarbonate (nahco3) is heated, it decomposes into sodium carbonate (na2co3), carbon dioxide (co2), and water (h2o).
- When arsenic trioxide (as2o3) is heated, it decomposes into pure arsenic (as) and oxygen (o2) gas.
Therefore, the products formed when ch3cooh, nahco3, and as2o3 are individually heated are acetic anhydride (ch3cooCH3), sodium carbonate (na2co3), carbon dioxide (co2), water (h2o), pure arsenic (as), and oxygen gas (o2).
