The specific heat capacity of ethanol is 2.46 joules per gram.
Now, we may use the equation:
Energy = mass * specific heat capacity * change in temperature
Here we may substitute:
mass = density * volume
Energy = density * volume * specific heat capacity * change in temperature
720 = 0.789 * 35 * 2.46 * ΔT
ΔT = 10.6
The final temperature will be
20 + 10.6
= 30.6 °C
Answer: Salt is soluble in water, when salt is added to water most of it dissolves to make a solution. When sand is added to water it either hangs in the water or forms a layer at the bottom of the container. Sand therefore does not dissolve in water and is insoluble. It is easy to separate sand and water by filtering the mixture. Salt can be separated from a solution through evaporation. The water can also be recovered as well as the salt if the water vapour is trapped and cooled to condense the water vapour back into a liquid. This process is called distillation.
Explanation:
Addition Polymerization reaction also known as chain Polymerization reaction. Monomers must contain double bond as a functional group.
<h3>What is Polymerization Reaction? </h3>
The chemical reaction which involves the addition of monomers to form higher molecular mass molecules is known as polymerization. There are two basically two types of polymerization, one is chain-reaction (or addition) and the other is step-reaction (or condensation) polymerization.
<h3>Chain-reaction (addition) polymerization</h3>
One of the most common and important types of polymer reactions is chain-reaction (addition) polymerization. This type of polymerization involves three step process including two chemical entities. The first which is known simply as a monomer. It is initially exists as simple units. Normally in all cases, the monomers must have at least one carbon-carbon double bond. Ethylene is one of the best known example of a monomer which is used to make a common polymer.
<h3>
Step-reaction (condensation) polymerization </h3>
It is second type of polymerization reaction. This polymerization method is used to produce polymers having lower molecular weight as compared to chain reactions and requires higher temperatures to occur.
In this type of reaction, monomers must have two functional group.
Thus, we concluded that the Monomers must contain double bond as a functional group in addition Polymerization reaction.
