Answer : The correct option is, (D)
Explanation :
Binary ionic compound : It is a type of compound that is made up of the ions of the two different elements in which one element is a metal and another element is a non-metal. It is only made up of two elements.
From the given options, option (A) is a binary ionic compound because in this compound Mn is a metal which combine with the an oxygen non-metal element.
While the other options are not a binary compound because it is made up of more than two elements.
Hence, the is a binary ionic compound.
Cu + 2H2SO4 ⟶ CuSO4 + SO2 + 2H20
In left hand side of the equation.
Cu = 1 atom
H = 4 atoms
S = 2 atoms
O = 8 atoms
In right hand side of the equation.
Cu = 1 atom
S = 2 atoms
0 = 8 atoms
H = 4 atoms
• All the atoms are balanced in the left and right side of the equation and it satisfies the law of conservation of mass.
• Equation is balanced and correct.
