36.46 g/mol is the answer
Answer:
1.306 × 10^24 formula units.
Explanation:
The chemical equation of this qkrstios as follows:
Fe + 2H2O → FeO2 + 2H2
Based on the reaction, 2 mole of H2O produces 1 mole of FeO2
Using the formula as follows;
Mole = mass/molar mass
Molar mass of H2O = 1(2) + 16 = 18g/mol
mole = 78/18
mole = 4.33moles
If 2 mole of H2O reacts to produce 1 mole of FeO2
4.33 moles of H2O will produce 4.33/2 = 2.17moles of FeO2.
To convert moles to formula units, we multiply number of moles by Avagadro number (6.02 × 10^23 units)
= 2.17 moles × 6.02 × 10^23 units
= 13.06 × 10^23
= 1.306 × 10^24 formula units.
Answer:
A Half Life
Explanation:
The half life is the time it takes for the substance to become reduced by half as a consequence of decay.
I believe the correct answer is C it would make the value of the left side equal to 4 and the value to the right side also equal to 4
Answer:
The reaction H2O(g)+C(s) -> CO(g)+ H2(g) is NOT spontaneous because its ΔG = 91 kJ/moles
Explanation:
ΔG is calculated by ΔH - TΔS
ΔG = ΔH - TΔS
ΔG = 131.3 kJ/mole - 298K . 0,134kJ/mole K
ΔG = 91.068 kJ/moles
Be careful with the ΔS, because you have J, and in ΔH, you have kJ
