how would the mass of water formed in the reaction compare to the mass of oxygen and hydrogeb that reacts.
in your response be sure to:
include they type of change illustrated in the balanced eqaution
explain the conservation of matter and determine the unknown amount of mass
explain the production of water.
The balanced equation you provided is:
2H2 + O2 = 2H2O
From the equation, we can determine the molar ratios. This means that 2 moles of H2 react with 1 mole of O2 to produce 2 moles of H2O.
To calculate the unknown mass, we start by determining the molar masses of each element:
- The molar mass of H2 is 2 grams/mol (since each H2 molecule weighs 2 grams).
- The molar mass of O2 is 32 grams/mol (as each O2 molecule weighs 32 grams).
Now, let's calculate the mass of water formed:
2 moles of H2O = 2 * (2 grams + 16 grams) = 36 grams
Next, let's compare the masses. Add the masses of oxygen and hydrogen together:
2 grams (H2) + 32 grams (O2) = 34 grams
Therefore, the mass of water formed (36 grams) is greater than the combined mass of oxygen (32 grams) and hydrogen (2 grams). This difference in mass is due to the fact that during the chemical reaction, new bonds are formed, resulting in a decrease in total mass.
The type of change illustrated in the balanced equation is a chemical change. In this case, the reactants (H2 and O2) combine to form new products (H2O). This is known as a synthesis reaction.
The conservation of matter principle states that matter cannot be created or destroyed in a chemical reaction. The total mass of the reactants will always be equal to the total mass of the products. This principle is evident in the balanced equation, where the total mass of hydrogen and oxygen in the reactants is equal to the total mass of water formed as the product.
In summary, the balanced equation shows the reaction of hydrogen and oxygen to form water. The mass of water formed is greater than the combined mass of oxygen and hydrogen, illustrating the conservation of matter in a chemical reaction.
