Answer:
C₆H₁₂
Explanation:
Given molecular weight = 84 g/mole
Empirical Formula => CH₂
Empirical Formula Wt = 12 + 2(1) = 14 g/emp formula
Molecular Multiple = Molecular Wt / Emp Formula Wt = 84/14 = 6
∴ Molecular Formula => (CH₂)₆ => C₂H₆
Answer:
C6H12
Explanation:
Molar mass of C =12.0 H=1.0
12x + 2(1x) = 84
x = 6
so it should be C6H12

Answer:
chemical energy
Explanation:
O3 + M2+(aq) + H2O(l) => O2(g) + MO2(s) + 2 H+
Eo(cell) = Eo(O3/O2) - Eo(MO2/M2+)
0.44 = 2.07 - Eo(MO2/M2+)
Eo(MO2/M2+) = 1.59 V
