How do the percent compositions for C3H6 and C4H7 compare?

Chemistry

A. They are the same

<h3>Further explanation</h3>

Given

C3H6 and C4H8

Required

The percent compositions

Solution

  • C₃H₆(MW = 42 g/mol)

%C = 3.12/42 x 100% = 85.71%

%H = 6.1/42 x 1005 = 14.29%

C₄H₈(MW=56 g/mol)

%C = 4.12/56 x 100% = 85.71%

%H = 8.1/56 x 100%=14.29%

So they are the same, because mol ratio of C and H in both compounds is the same, 1: 2

How does Bohr’s model of the atom compare with Thomson’s model?
Ilya [14]
Bohr's model of the atom states that electrons orbit an atom's nucleus in electron shells of increasing energy. The electrons are free of physical contact with the nucleus, but are held in orbit due to the electrons' attraction to the oppositely charged protons in the nucleus.
Thomson's model, or the plum pudding model, it describes atoms as spheres of positively charged matter, in which electrons are embedded in.
The key difference is the locations of, and the motions of the electrons.
