Determine the volume of an unknown solid given that the density is 6.5g/cm3 and the mass is 2.6g*
Choose one of the below
0.2 cubic cm
O 0.3 cubic cm
0.4 cubic cm
O
0.5 cubic cm

Ibelieve the answer is balance! hope my answer has you : )

Answer is: hydrogen is being oxidized.chemical reaction: co₂ + h₂ → co + h₂o.oxidation half reaction: h₂ → 2h⁺ + 2e⁻.reduction half reaction: c⁺⁴ + 2e⁻ → c⁺².oxidation is increase of oxidation number, hydrogen change oxidation number from neutral charge (in molecule of hydrogen) to oxidation number +1 (in water).
