Explanation:
1)
The amount of energy that must be absorbed by a certain substance in order to increase its temperature by is given by the equation:
where
m is the mass of the substance
C is its specific heat capacity
is the increase in temperature of the substance
For the block of copper in this problem, we have:
m = 10 g is the mass
is the specific heat capacity of copper
is the change in temperature
So, the energy absorbed by the block of copper is
2)
Similarly for the block of iron, the energy absorbed by the iron is given by
where
m is the mass of the block of iron
C is its specific heat capacity of iron
is the increase in temperature of the block
Here we have:
m = 10 g is the mass of the block
is the specific heat capacity of iron
is the change in temperature
So, the energy absorbed by the block of iron is
Answer:
<span>Based on giveninformation, the compound is a <u>Poly Unsaturated</u> fatty acid.
Explanation:
Fatty acids are carboxylic acids with -COOH functional group and a chain of hydrocarbons.
Fatty Acids are classified as,
i) Saturated Fatty Acids:
Those Fatty Acids in which there is no double bond between the carbon chain are called as saturated fatty acids.
Examples:
Lauric Acid </span>CH₃(CH₂)₁₀COOH<span>
Myristic Acid </span>CH₃(CH₂)₁₂COOH<span>
Palmitic Acid </span>CH₃(CH₂)₁₄COOH
ii) Unsaturated Fatty Acids:
Those Fatty Acids in which contain a single double bond (mono-unsaturated) or more than one double bond (poly-unsaturated) d between the carbon atoms in a chain are called as unsaturated fatty acids.
Examples:
<span>Linoleic acid
</span>
<span>Vaccenic acid
</span><span>Palmitoleic acid
The saturated fatty acid containing 26 carbon atoms is called as Cerotic acid. While cerotic acid containing a double bond at position 3 and 9 has a IUPAC name H</span>exacosa-3,9-dienoic acid with following structure.
