Select the Newman projection that corresponds to the following molecule 2. Select the choice that best describes the relationshi
p of the following pair of compounds
2 answers:
Both compounds have cis-trans geometry isomers
Both carbon compounds have a double bond and both carbon atoms bind two different groups
<h3>Further explanation </h3>Isomers are two compounds that have the same chemical formula but different structural formulas
There is a grouping of isomers in Hydrocarbons:
- 1. Isomer structure consists of skeletal isomers, position isomers, and function isomers
- 2. Stereoisomers consist of geometric isomers and optical isomers
Geometric isomers occur because of differences in the direction of the groups in the molecule
geometrical isomers are found in compounds that have double bonds such as alkenes and the two atoms bind 2 different groups, so that if the location of the groups is exchanged the shape becomes different
If a similar group is located on the same side of the double bond it is called -cis, but if the group is opposite it is called -trans
Example:
Atomicity to 2 butenes. Where in cis-2 butene, both methyl groups are located on the same side whereas, in trans-2 butene, both methyl groups are opposite
The difference in the structure of the two compounds results in differences in physical properties such as the boiling point
The greater the number of carbon atoms making up it, the more the number of isomers

Answer : The final equilibrium temperature of the water and iron is, 537.12 K
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of iron = 560 J/(kg.K)
= specific heat of water = 4186 J/(kg.K)
= mass of iron = 825 g
= mass of water = 40 g
= final temperature of water and iron = ?
= initial temperature of iron =
= initial temperature of water =
Now put all the given values in the above formula, we get:
Therefore, the final equilibrium temperature of the water and iron is, 537.12 K
