MC₂H₄O₂ = 2 * 12 g/mol + 4 * 1 g/mol + 2 * 16 g/mol = 60 g/mol
c = 0.5 mol/L
V = 1 L
n = c * V
n = 0.5 mol/L * 1 L = 0.5 mol
m = n * M
m = 0.5 mol * 60 g/mol = 30 g/mol
answer E
(-_-(-_-)-_-)
Answer:
Option B
Explanation:
Remember that the products are on the right side of a chemical equation while the reactant is on the left.
In this case we have...
C2H6 + O2 ⇒ CO2 + H2O
Since C2H6 and O2 are on the left side that would mean they're the reactants, while CO2 + H2O are the products. Which means your answer is option B or "C2H6 + O2 are the reactants, CO2 + H2O are the products."
