Tardigrade Admin · Accepted Answer

[Ca → Ca2++2e-]× 3 [Al3++3e-→ Al] × 2] ( beginmatrix beginmatrix3Ca →3Ca2++6e- 2Al3++6e- →2Al endmatrix endmatrix/3Ca+2Al3+→3Ca2++2Al) Therefore, the stoichiometric coefficient of Ca in the given reaction is 3

Q. What is the stoichiometric coefficient of $C a$ in the reaction?
$C a + A l^{3 +} \to C a^{2 +} + A l$

$[C a \to C a^{2 +} + 2 e^{-}] \times 3$
$[A l^{3 +} + 3 e^{-} \to A l] \times 2]$
$\frac{3 C a \to 3 C a ^{2 +} + 6 e ^{-} 2 A l ^{3 +} + 6 e ^{-} \to 2 A l}{3 C a + 2 A l ^{3 +} \to 3 C a ^{2 +} + 2 A l}$
Therefore, the stoichiometric coefficient of Ca in the given reaction is $3$
