The mass of ethanol is consumed by the reaction of 3.37g oxygen gas is 4.85g
Explanation:
The balanced equation for the chemical reactions is;
CH₃CH₂OH + O₂ → CH₃COOH + H₂O
The mole ratio between oxygen and ethanol in the reaction is 1 : 1
The molar mass of O₂ is 32g / mole. Therefore the O₂ moles consumes in the reaction is;
3.37 / 32
If the molar mass of ethanol is 46.07g/mole, and the ration of reaction in 1 : 1; Then the moles of ethanol consumed is;
3.37/32 * 46.07
= 4.85g
Answer:
Yes, a chemical change occurs.
Explanation:
CaSO4 is insoluble in the water, so a chemical reaction or chemical change occurs.
