Identify the balanced single displacement reaction.
2 answers:
Answer:
Explanation:
This is a single replacement reaction in which iron replaces copper from its salt solution. As iron is more reactive than copper , it easily loses electrons to convert to in
and
in
accepts electrons to form
.
The equation is also balanced as equal number of atoms of each element are present on reactant and product side.
1. : The equation is not balanced.
2. : This is a double displacement reaction and is balanced.
4. : This is a double displacement reaction and is not balanced.

Answer:
87.15%
Explanation:
To find percent yield, we can use this simple equation
Where "Actual" is the amount in grams actually collected from the reaction, and "Theoretical" is, well, the theoretical amount that should have been produced.
They give us these values, so to find the percent yield, just plug the numbers in.
So, the percent yield is 87.15%
An easy trick to remember how to do this is just to divide the smaller number by the bigger number and move the decimal back two places. If you have a percent yield greater than 100%, something is wrong in the reaction.
Answer:
35.1 kJ/mol is the expected value for the heat of sublimation of acetic acid.
Explanation:
..[1]
Heat of vaporization of acetic acid =
..[2]
Heat of fusion of acetic acid =
Heat of sublimation of acetic acid =
..[3]
[1] + [2] = [3] (Hess's law)
35.1 kJ/mol is the expected value for the heat of sublimation of acetic acid.
