(4) HBr and H2SO4 is the correct answer.
Hope this would help~
Answer:
X₃Z₂
Explanation:
A metal ion (X) with a charge of 2+ = X²⁺
nonmetal ion (Z) with a charge of 3- = Z³⁻
In a neutral compound, the charges but balance each other to remain neutral. However in this case, the charges are not balanced.
A simple way to make the charges balance is by tweaking the number of the ions present in the compound.
We do this by multiplying the metal ion with 3 and the non metal ion by 2.
That way we have;
Metal ion = 3X2⁺ (Total charge - 6⁺)
Non metal ion = 2Z3⁻ (Total charge - 6⁻)
The charges are now balanced. The formular of the compound is;
X₃Z₂
Answer:
