Question

N₂O₅ + H₂O➡️HNO₃ KClO₃➡️KCl + O₂⬆️ Na+H₂O ➡️ NaOH + H₂⬆️ NO₂➡️No + O₂

Answer 1

Ответ:

Объяснение:

N2O5 + H2O = 2HNO3

2KClO3 -> 2KCl + 3O2

2Na + 2H2O = 2NaOH + H2

2NO2 -> 2NO + O2

Answer 2

The chemical reactions you provided are balanced chemical equations representing different reactions. Here's a breakdown of each reaction:

1. N₂O₅ + H₂O ➡️ 2HNO₃: Nitrogen pentoxide (N₂O₅) reacts with water (H₂O) to produce two molecules of nitric acid (HNO₃).

2. 2KClO₃ ➡️ 2KCl + 3O₂⬆️: Two molecules of potassium chlorate (KClO₃) decompose to form two molecules of potassium chloride (KCl) and release three molecules of oxygen gas (O₂).

3. 2Na + 2H₂O ➡️ 2NaOH + H₂⬆️: Two sodium atoms (Na) react with two molecules of water (H₂O) to produce two molecules of sodium hydroxide (NaOH) and release one molecule of hydrogen gas (H₂).

4. 2NO₂ ➡️ 2NO + O₂: Two molecules of nitrogen dioxide (NO₂) decompose to form two molecules of nitric oxide (NO) and release one molecule of oxygen gas (O₂).

Please note that in chemical reactions, it's essential to balance the equations to ensure that the number of atoms on both sides of the equation is the same.
