Yes, you are correct.

Explanation:

Examples:

$+ 1 K + 7 Mn {-2 O}_{4} + {+ 1 Na}_{2} {+ 3 C}_{2} {-2 O}_{4} + {+ 1 H}_{2} + 6 S {-2 O}_{4} \to {+ 1 K}_{2} + 6 S {-2 O}_{4} + {+ 1 Na}_{2} + 6 S {-2 O}_{4} + + 2 Mn + 6 S {-2 O}_{4} + + 4 C {-2 O}_{2} + {+ 1 H}_{2} -2 O$ $stackrelcolor(blue)(+1)("K")stackrelcolor(blue)(+7)("Mn")stackrelcolor(blue)("-2")("O")_4 + stackrelcolor(blue)(+1)("Na")_2stackrelcolor(blue)(+3)("C")_2stackrelcolor(blue)("-2")("O")_4 + stackrelcolor(blue)(+1)("H")_2stackrelcolor(blue)(+6)("S")stackrelcolor(blue)("-2")("O")_4 → stackrelcolor(blue)(+1)("K")_2stackrelcolor(blue)(+6)("S")stackrelcolor(blue)("-2")("O")_4 + stackrelcolor(blue)(+1)("Na")_2stackrelcolor(blue)(+6)("S")stackrelcolor(blue)("-2")("O")_4 + stackrelcolor(blue)(+2)("Mn")stackrelcolor(blue)(+6)("S")stackrelcolor(blue)("-2")("O")_4 + stackrelcolor(blue)(+4)("C")stackrelcolor(blue)("-2")("O")_2 + stackrelcolor(blue)(+1)("H")_2stackrelcolor(blue)("-2")("O")$

Some atoms that underwent change of oxidation number after the reaction.

$Mn: +7 \to +2; Change = -5$ $"Mn: +7 → +2; Change = -5"$
$C: +3 \to +4; Change = +1$ $"C: +3 → +4; Change = +1"$
