Answer:
4 moles CO₂ = 4 moles O₂
Explanation:
The incorrect mole ratio is 4 moles CO₂ = 4 moles O₂.
Let us write the reaction equation:
2C₂H₅OH + 7O₂ → 4CO₂ + 6H₂O
To write mole ratios in a chemical reaction, we must ensure the equation is balanced.
Since the given expression is balanced,
Then 4 moles CO₂ = 4 moles O₂ is not correct;
Rather;
4 moles CO₂ = 7 moles O₂ is the right expression

Answer-The correct option is option d with says all of the above.
Explanation- All three acids that are given combined together to form acid rain in which nitric and sulphuric acid are stronger acids present while carbonic acid is a weaker one.
The carbon dioxide admitted in air combines with water to form carbonic acid and gives a weak acidic nature to rainwater. Pollution in nature makes sulphur and nitrogen present in air react to form the stronger acids responsible for acid rain.
Answer: Option (a) is the correct answer.
Explanation:
Since it is given that the mass of a jelly bean is less than the mass of a gum drop.
So, when we counted out 10 of each kind of candy and measured the mass of each kind of candy, the mass of the jellybeans would be less than the mass of the gumdrops.
This is because mass of jelly bean is less and even if we take take or more jelly beans then also their total mass will remain less than the total mass of same number of gum drops.
