Explanation:
Hope the picture with the working out helps :)
Answer is: molar mass of molecular compound is 71,95 g/mol.
N(compound) = 8,35·10²¹.
n(compound) = N(compound) ÷ Na.
n(compound) = 8,35·10²¹ ÷ 6,022·10²³ 1/mol.
n(compound) = 0,0139 mol.
m(compound) = 1,00 g.
M(compound) = m(compound) ÷ n(compound).
M(compound) = 1 g ÷ 0,0139 mol.
M(compound) = 71,95 g/mol.
Answer:
The geological time from the longest to the shortest are:
- Eon,
- Era,
- Period and,
- Epoch.
The chemical reaction is:
<span>2CuO+C→2Cu+CO2
The oxidizing agent is the one that is being reduced which is copper from a charge of +2 to a neutral charge or zero. The opposite is called the reducing agent which is carbon for this case.
