Question

Ni2T3 --> Ni + T2

Answer 1

Balance by inspection:

Let coefficients be 1·Ni2T3 → x·Ni + y·T2.

Ni: 2 = x → x = 2
T: 3 = 2y → y = 3/2

Multiply through by 2 to clear the fraction:

2 Ni2T3 → 4 Ni + 3 T2

Check: Ni atoms 4 = 4; T atoms 6 = 6. This is the balanced equation (decomposition).
