If `m_(1)` and `m_(2)` are masses of two reactants in any reaction, having their gram equivalent masses `E_(1)` and `E_(2)` respectively, which of the following equatios represents the law of equivence correctly?

Options

A. `m_E_=m_(2)E_(2)`
B. `m_(1)m_(1)=E_(1)E_`
C. `m_(1)E_(2)=m_(2)E_(1)`
D. `sqrt(m_(1)//E_(1))=sqrt(m_(2)//E_(2))`

Answer

3

Explanation

According to the law of equivalence, the number of equivalent of different substances (reactants and products) involved in a given chemical reaction are always equal. Thus
`m_(1)/E_(1)=m_(2)/E_(2)`
or `m_(1)E_(2)=m_(2)E_(1)`
