Answer:
Ethane would have a higher boiling point.
Explanation:
In this case, for the lewis structures, we have to keep in mind that all atoms must have <u>8 electrons</u> (except hydrogen). Additionally, each carbon would have <u>4 valence electrons</u>, with this in mind, for methane we have to put the hydrogens around the carbon, and with this structure, we will have 8 electrons for the carbon. In ethane, we will have a bond between the carbons, therefore we have to put three hydrogens around each carbon to obtain 8 electrons for each carbon.
Now, the main difference between methane and ethane is an <u>additional carbon</u>. In ethane, we have an additional carbon, therefore due to this additional carbon, we will have <u>more area of interaction</u> for ethane. If we have more area of interaction we have to give <u>more energy</u> to the molecule to convert from liquid to gas, so, the ethane will have a higher boiling point.
I hope it helps!
Cnidarians have two body forms—polyp and medusa—which often occur within the life cycle of a single cnidarian. The body of a medusa, commonly called a jellyfish, usually has the shape of a bell or an umbrella, with tentacles hanging downward at the margin.
An example of the polyp form is found in the genus Hydra, whereas the most typical form of medusa is found in the group called the “sea jellies” (jellyfish). Polyp forms are sessile as adults, with a single opening (the mouth/anus) to the digestive cavity facing up with tentacles surrounding it.

The answer is actually C. endorphins. during regular exercise, the pituitary gland and central nervous system produce endorphins
Answer:
The mass is 
Explanation:
From the question we are told that
The volume of oxygen produced is 
The temperature is 
The pressure is 
From the ideal gas law we have that
Where R is the gas constant with the value
n is the number of moles making it the subject of the formula
Substituting values
From the chemical equation
one mole of 
produces one mole of kCl and 
of oxygen
x mole of produces x mole of kCl and 
of oxygen
So 
Now the molar mass of KCl is a constant with a value
Now the mass of KCl is mathematically evaluated as
Substituting values
The number of valence electrons for each molecule or ion is shown beneath the structure. Remember hydrogen will not have more than two electrons. This hydrogen is part of a covalent bond (sharing two electrons). A double bond here would cause hydrogen to share four electrons with phosphorus.
