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:
Tapeworms and roundworms both belong to the same phylum however, their families are different from one another.
Tapeworms are flat, segmented intestinal parasites of the cat and dog and humans sometimes. They are present in the intestines of pets and depend on them, therefore, are parasites. These parasites look like tape which gives it its name.
Roundworms can also infect humans and the most common cases are among children. When not treated immediately, they can cause severe damage to a human host and can even cause blindness. Tapeworms are white in color with a long, segmented body.
