Answer:

A) C3H4

Explanation:

We have to remember that for each c<u>arbon we must have 4 bonds</u>. In a three-carbon alkene we will have 2 bonds for the <u>left carbon</u>, 4 bonds for the<u> central carbon</u> and 2 bonds for the <u>right carbon</u> (Figure 1). Therefore we have to add <u>2 hydrogens in the left carbon and 2 hydrogens for the right carbon</u>. Finally, if we count the number of carbons and hydrogens we will get C3H4.

Helium gas diffuses 4 times as fast as an unknown gas. What is relative molecular mass of the gas​
Inessa05 [86]

The relative molecular mass of the gas​ : 64 g/mol

<h3>Further explanation</h3>

Given

Helium rate = 4x an unknown gas

Required

The relative molecular mass of the gas​

Solution

Graham's Law

\tt \dfrac{r_1}{r_2}=\sqrt{\dfrac{M_2}{M_1} }

r₁=4 x r₂

r₁ = Helium rate

r₂ = unknown gas rate

M₁= relative molecular mass of Helium = 4 g/mol

M₂ = relative molecular mass of the gas​

Input the value :

\tt \dfrac{4r_2}{r_2}=\sqrt{\dfrac{M_2}{4} }\\\\16=\dfrac{M_2}{4}\\\\M_2=64~g/mol
