Answer:

C.  

Explanation:

Stereoisomers are molecules that have the same molecular formula and with their atoms connected in the same way but pointing in different directions.

<em>cis</em>-Pent-2-ene has formula C₅H₁₀

A. is wrong, because its formula is C₅H₁₂

B. and D. are wrong, because their formulas are C₅H₈

The only option left is C. It has formula C₅H₁₀

C. is a stereoisomer of <em>cis</em>-pent-2-ene, because atoms 1 and 4 are on opposite sides of the double bond.

Think of the C=C bond as a river.

In the <em>cis </em>isomer (top), atoms 1 and 4 are on the same side of the river (zis = zame zide).

In the <em>trans</em> isomer (bottom), atoms 1 and 4 are on opposite sides of the river (trans = across or opposite).

So, C. is a stereoisomer of cis-pent-2-ene.

Which relationship can be used to aid in the determination of the heat absorbed by bomb calorimeter? 
NARA [144]

Answer:

ΔH = q_{p}

Explanation:

In a calorimeter, when there is a complete combustion within the calorimeter, the heat given off in the combustion is used to raise the thermal energy of the water and the calorimeter.

The heat transfer is represented by

q_{com} = q_{p}

where

q_{p} = the internal heat gained by the whole calorimeter mass system, which is the water, as well as the calorimeter itself.

q_{com}  = the heat of combustion

Also, we know that the total heat change of the any system is

ΔH = ΔQ + ΔW

where

ΔH = the total heat absorbed by the system

ΔQ = the internal heat absorbed by the system which in this case is q_{p}

ΔW = work done on the system due to a change in volume. Since the volume of the calorimeter system does not change, then ΔW = 0

substituting into the heat change equation

ΔH = q_{p} + 0

==> ΔH = q_{p}
