Answer:- none
Explanations:- For naming hydrocarbons we use the suffix -ane, -ene and -yne.
-ane is used when we have only single bonds between all carbons. -ene is used if there is any double bond between two carbons and the -yne is used if there is any triple bond between two carbons.
The given name of the compound is propane. It ends at -ane and so it's an alkane and must have single bonds between all the carbons it has. So, there are zero double bonds present in 
.
This is also clear from the below lewis dot structure of the compound.
Answer:
I think the answer is 22.2
Explanation: What i DID was adding 12.0 + 10.0 and than that gave me 22 the I had added the to 0.200 and that how i got 22.2. Sorry if i got is wrong. :(
The salt and water are a homogeneous mixture but when salt dissolves in the water system is called a solution of salt and water.
<h3>What is a mixture? </h3>
A mixture is defined as the combination of two or more substances that are not chemically bonded together.
There are two types of mixture which include:
- Homogeneous (uniform composition) and
When salt is added to the ice water system, it lowers the freezing point of the ice water thereby forming a homogenous mixture of water and salt.
The dissolution of salt in ice water leads to the formation of salt and water solution.

It starts at the bottom and then it goes up into the air as evaporation and that’s when the air gets cooler so gas is cooler and the liquid would be hotter
