Analyze the pieces of the chemical reaction.
16 grams CH4
44 grams CO2
64 grams O2
36 grams H2O
Organize the reactants (what was present before the reaction) and the products (what is present after the reaction) so that the law of conservation of mass has been observed. Explain the law of conservation of mass and describe how the equation represents the law of conservation of mass.
The number of atoms will not change
16g CH4 is 1C and 4H
do the others the same way, then balance the two sides so they have the same # atoms in total, for each element
The law of conservation of mass states that in a chemical reaction, matter is neither created nor destroyed. Instead, it is rearranged to form new substances. This means that the mass of the reactants should be equal to the mass of the products.
In this chemical reaction, we have:
Reactants:
- 16 grams CH4
- 64 grams O2
Products:
- 44 grams CO2
- 36 grams H2O
To analyze the pieces of the chemical reaction, we can break it down as follows:
1. Calculate the total mass of the reactants:
16 grams CH4 + 64 grams O2 = 80 grams
2. Calculate the total mass of the products:
44 grams CO2 + 36 grams H2O = 80 grams
By comparing the total mass of the reactants (80 grams) to the total mass of the products (80 grams), we can see that the law of conservation of mass is observed. The total mass before the reaction is the same as the total mass after the reaction has occurred.
The equation represents the law of conservation of mass by balancing the mass of the reactants with the mass of the products. It shows that the combined mass of the reactants is equal to the combined mass of the products, indicating that no mass has been created or lost during the chemical reaction.
The law of conservation of mass states that in a chemical reaction, the total mass of the reactants is equal to the total mass of the products. This means that atoms are neither created nor destroyed during a chemical reaction, but they can rearrange to form new substances.
To analyze the given chemical reaction, we need to examine the mass of the reactants and products:
Reactants:
16 grams CH4 (methane)
64 grams O2 (oxygen)
Products:
44 grams CO2 (carbon dioxide)
36 grams H2O (water)
To organize the reactants and products so that the law of conservation of mass is observed, we have to ensure that the total mass on both sides of the chemical equation is the same.
The balanced chemical equation for the reaction between methane and oxygen to produce carbon dioxide and water is:
CH4 + 2O2 -> CO2 + 2H2O
According to the equation, the reaction requires one molecule of methane and two molecules of oxygen to produce one molecule of carbon dioxide and two molecules of water. Now, let's calculate the mass of each side of the equation:
Reactants:
16 grams CH4
64 grams O2
Total mass of reactants = 16 grams CH4 + 64 grams O2 = 80 grams
Products:
44 grams CO2
36 grams H2O
Total mass of products = 44 grams CO2 + 36 grams H2O = 80 grams
As we can see, the total mass of the reactants is equal to the total mass of the products (80 grams), satisfying the law of conservation of mass.
In summary, the law of conservation of mass states that during a chemical reaction, the total mass of the reactants is equal to the total mass of the products. The given chemical equation, CH4 + 2O2 -> CO2 + 2H2O, represents the law as the total mass of the reactants (16 grams CH4 + 64 grams O2) is equal to the total mass of the products (44 grams CO2 + 36 grams H2O), both equaling 80 grams.
