<u>Answer: </u>54 molecules of water will be formed in the reaction.
<u>Explanation:</u>
A balanced chemical equation is one where all the individual atoms are equal on both sides of the reaction. It follows the law of conservation of mass.
For the given unbalanced chemical equation, the balanced equation follows:
We are given:
Molecules of = 6
Molecules of = 75
By the stoichiometry of the reaction:
If 2 molecules of produces 18 molecules of water
So, 6 molecules of will produce = molecules of water
Hence, 54 molecules of water will be formed in the reaction.
Answer:
3.30 gSiO2 / 60.085g SiO2 x 2 mol 0 / 1 mol SiO2 x (6.022*1023 ) = 6.61*1022 O atoms
Explanation:
<u>Answer:</u> The mass of oxygen reacted is
<u>Explanation:</u>
We are given:
Moles of propane = 9.98 mol
For the given chemical equation:
By Stoichiometry of the reaction:
1 mole of propane reacts with 5 moles of oxygen.
So, 9.98 moles of propane will react with = of oxygen.
To calculate the mass of carbon dioxide, we use the equation:
Moles of oxygen = 49.9 moles
Molar mass of oxygen gas = 32 g/mol
Putting values in above equation:
Hence, the mass of oxygen reacted is
