A student carries out this chemical reaction in a beaker:
1 answer:
Answer:The correct answer is option (C).
Explanation:
After the reaction between Zinc and copper(II) chloride, Zinc chloride and copper will be obtained as a product. This reaction occurs because zinc is more reactive than copper which displaces the copper from its aqueous solution.
The student will expect to find copper metal at bottom of the beaker with aqueous solution of zinc chloride.
Hence the correct answer is option (C).

Answer:
- 0.07 °C
Explanation:
At constant pressure and number of moles, Using Charle's law
Given ,
V₁ = 439 mL = 0.439 L ( 1 L = 0.001 mL )
V₂ = 0.378 L
T₁ = 317.15 K
T₂ = ?
Using above equation as:
The conversion of T(K) to T( °C) is shown below:
T( °C) = T(K) - 273.15
So, <u>T = 273.08 - 273.15 °C = - 0.07 °C</u>
Answer : The structural formulas for each of the possible isomers of n-hexene are shown below.
Explanation :
Isomer : It is defined as a molecule have the same molecular formula but the different chemical structure.
There are three structural isomers of n-hexene that is based on the location of the double-bonded carbon atoms with the other atoms.
In n-hexane, 'n' shows that the chain should be straight chain there is no branching.
The three structural isomers of n-hexene are:
(1) 1-hexene
(2) 2-hexene
(3) 3-hexene
Thus, the structural formulas for each of the possible isomers of n-hexene are shown below.
