The most abundant elements by mas in the body of a healthy human adult

1.	The most abundant elements by mas in the body of a healthy human adult are Oxygen `(61.4%)`, Carbon `(22.9%)`. Hydrogen `(10.0)%)`, and Nitrogen `(2.6%)`. The weight which a `75 kg` person would gain if all `.^(1)H` atoms are replaced by `.^(2)H` atoms isA. 37.5 kgB. 7.5 kgC. 10 kgD. 15 kg
Answer» Correct Answer - B 75 kg person contain 10% hydrogen i.e. 7.5 kg Hydrogen. If all H atom are replaced by `.^(2)H`, the weight of Hydrogen become twice i.e., it increased by 7.5 kg

Which of the following statements is correct about the reaction given below:- `4Fe(s)+3O_(2)(g)rarr2Fe_(2)O_(3)(g)`A.
