What are the number of reactants and the number of compounds in; 2H2(g)+O2(g)=2H2O(I)
To determine the number of reactants and compounds in a chemical equation, you need to understand the notation used to represent elements and compounds. Let's break down the given chemical equation:
2H2(g) + O2(g) = 2H2O(I)
In this equation, the reactants are the chemicals on the left side of the equation (2H2(g) and O2(g)), and the compounds are the chemicals on the right side of the equation (2H2O(I)).
Let's analyze the reactants first:
- "2H2(g)" represents hydrogen gas (H2) and the coefficient "2" indicates that there are two molecules of hydrogen gas as reactants. Therefore, there are 2 reactants consisting of hydrogen gas.
- "O2(g)" represents oxygen gas (O2). Here, there is only one molecule of oxygen gas as a reactant.
Now, let's consider the compounds:
- "2H2O(I)" represents water (H2O). The coefficient "2" indicates that there are two molecules of water as products. Therefore, there are 2 compounds consisting of water.
In summary, in the given chemical equation, there are 2 reactants (hydrogen gas and oxygen gas) and 2 compounds (water) involved.
