Write word equations for the following chemical reactions.
a. Pure copper can be produced by heating copper(II) sulfide in the
presence of diatomic oxygen from the air. Sulfur dioxide gas is also
produced in this reaction.
b. Water is formed by the explosive reaction between hydrogen gas
and oxygen gas.
c. When baking soda (sodium hydrogen carbonate) is heated, it decomposes,
forming the products sodium carbonate, carbon dioxide,
and water.
Idk how to do
I will be happy to critique your work on this.
a. Copper(II) sulfide + Oxygen → Copper + Sulfur dioxide
b. Hydrogen gas + Oxygen gas → Water
c. Sodium hydrogen carbonate (Baking soda) → Sodium carbonate + Carbon dioxide + Water
a. To write the word equation for the reaction between copper(II) sulfide and diatomic oxygen to produce pure copper and sulfur dioxide, we need to identify the reactants and products involved:
Reactants:
- Copper(II) sulfide
- Diatomic oxygen (O2)
Products:
- Pure copper
- Sulfur dioxide
The word equation for this reaction would be:
Copper(II) sulfide + Diatomic oxygen → Pure copper + Sulfur dioxide
b. For the explosive reaction between hydrogen gas and oxygen gas to form water, we can determine the reactants and products:
Reactants:
- Hydrogen gas (H2)
- Oxygen gas (O2)
Product:
- Water (H2O)
The word equation for this reaction would be:
Hydrogen gas + Oxygen gas → Water
c. To represent the decomposition of baking soda (sodium hydrogen carbonate) when heated to form sodium carbonate, carbon dioxide, and water, we can identify the reactant and the products:
Reactant:
- Baking soda (Sodium hydrogen carbonate)
Products:
- Sodium carbonate
- Carbon dioxide gas
- Water
The word equation for this reaction would be:
Baking soda → Sodium carbonate + Carbon dioxide + Water
