Question
A chemical reaction can be used to turn water into two gases: hydrogen and oxygen.Determine which of the following statements about this reaction are true. Hydrogen is a reactantWater is a reactantA compound is converted into two elementsAn element is converted into two compounds
Solution
Sure, let's analyze each statement step by step:
-
Hydrogen is a reactant:
- In the given chemical reaction, water (H₂O) is broken down into hydrogen (H₂) and oxygen (O₂) gases.
- Therefore, hydrogen is not a reactant; it is a product.
- This statement is false.
-
Water is a reactant:
- Water (H₂O) is the substance that undergoes the chemical reaction to produce hydrogen and oxygen gases.
- Therefore, water is indeed a reactant.
- This statement is true.
-
A compound is converted into two elements:
- Water (H₂O) is a compound made up of hydrogen and oxygen.
- The reaction breaks down water into hydrogen (H₂) and oxygen (O₂), which are both elements.
- This statement is true.
-
An element is converted into two compounds:
- In this reaction, water (a compound) is broken down into hydrogen and oxygen (both elements).
- No element is being converted into compounds in this reaction.
- This statement is false.
So, the true statements are:
- Water is a reactant.
- A compound is converted into two elements.
