Answer:

CH₄

Explanation:

According to Graham's law, <em>the rate of effusion of a gas (r) is inversely proportional to the square root of its molar mass (M)</em>.

Let's consider the following gases and their molar masses.

A) NH₃    17.03 g/mol

B) CH₄    16.04 g/mol

C) Ar       39.95 g/mol

D) HBr    80.91 g/mol

E) HCl     36.46 g/mol

Of these gases, CH₄ will have the greatest rate of effusion at a given temperature because it has the lowest molar mass.

Alinara [238K]

Answer:

When you breathe in, or inhale, your diaphragm contracts and moves downward. This increases the space in your chest cavity, and your lungs expand into it. The muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.

Rank these compounds by their expected boiling point? CH4 CH3Cl CH3OH? Lowest to highest; 10+ for the best explanation. Thank yo
docker41 [41]
Methane, CH4, would have the lowest boiling point among the three since it has the lowest number of carbon and has no functional groups. Methanol would have the highest boiling point since it has a functional group which contains hydrogen bonding which much stronger than the one in CH3Cl. Hope this helps.<span />

Molecules that have the same chemical formula (same numbers of each atom) but different three-dimensional shapes are called ____
katen-ka-za [31]

The given blank can be filled with isomers.  

The isomers in chemistry refers to the molecules or ions with similar formulas, but different compositions. The isomers refer to the molecules that exhibit the same chemical formula, however, distinct three-dimensional shapes. Though isomers do not always share identical properties. The two prime forms of isomerism are stereoisomerism or spatial isomerism and structural isomerism or constitutional isomerism.
