Which of the following equations is balanced ? A 5 B i O 3 − ​ + 2 H + + M n 2 + → 5 B i 3 + + 7 H 2 ​ O + M n O 4 − ​ B 5 B i O 3 − ​ + 1 4 H + + 2 M n 2 + → 5 B i 3 + + 7 H 2 ​ O + 2 M n O 4 − ​ C 2 B i O 3 − ​ + 4 H + + M n 2 + → 2 B i 3 + + 2 H 2 ​ O + M n O 4 − ​ D 6 B i O 3 − ​ + 1 2 H + + 3 M n 2 + → 6 B i 3 + + 6 H 2 ​ O + 3 M n O 4 − ​

Omveer Singh · Answer

Here, the number of atoms of each type and charges on both sides (left and right of the equation) are same. So, the equation is balanced. 5 B i O 3 − ​ + 1 4 H + + 2 M n 2 + → 5 B i 3 + + 7 H 2 ​ O + 2 M n O 4 −
