Answer:
Hydrocarbons
Explanation:
They all are made up of only carbon and hydrogen atoms, so they're organic molecules known as hydrocarbons. Decane and Heptane are alkanes, Propene is an alkene.
Answer:
Empirical formula is CH₃.
Explanation:
Given data:
Mass of carbon = 120 g
Mass of hydrogen = 30.3 g
Empirical formula = ?
Solution:
Number of gram atoms of C = 120 g / 12 g/mol = 10
Number of gram atoms of H = 30.3 g / 1.008 g/mol = 30.06
Atomic ratio:
C : H
10/10 : 30.06/10
1 : 3.06
C : H = 1 : 3
Empirical formula is CH₃.
Explanation:
B. Recycles slowly
And it also depends on the organism
