Your answer is A. Weathered rocks and decomposed organic remains.
Basis of the calculation: 100g
For Carbon:
Mass of carbon = (100 g)(0.80) = 80 g
Number of moles of carbon = (80 g)(1 mole / 12g) = 20/3
For Hydrogen:
Mass of hydrogen = (100 g)(0.20) = 20 g
Number of moles of hydrogen = (20 g)(1 mole / 1 g) = 20
Translating the answer to the formula of the substance,
C20/3H20
Dividing the answer,
CH3
The molar mass of the empirical formula is:
12 + 3 = 15 g/mol
Since, the molar mass given for the molecular formula is 30.069 g/mol, the molecular equation is,
C2H6
ANSWER: C2H6

Answer: <span>There are more reactants than products at equilibrium.
Explanation:
</span>1) The equilibrium constant is defined as the ratio of the constant of reaction for the forward reaction divided by the constant of reaction for the reverse reaction.
2) If the constant of reacton for the forward reaction is greater than the constant of reaction for the reverse reaction, then the equilbrium constant is greater than 1 and the equilibrium is reached at a point where there are more products than reactants.
This is not the case given that the equilibrium constant is less than 1.
3) If the constant of reaction for the forward reaction is less than the constant of reaction for the reverse reaction, then the equilibrium constant is less than 1 and at equilibrium there will be more reactants than products.
This is the case given, since the equilibrium constant is 0.123.
Therefore, the answer is: there are more reactants than products at equilibrium.
