Answer:
1. Double displacement reaction
2. Trisodium phosphate and potassium hydroxide
3. Sodium hydroxide and Potassium phosphate
Explanation:
1)
The given chemical reaction is as follows.
The balanced chemical reaction is as follows.
In the above reaction two reactants are exchange their cations. Therefore, it is a double displacement reaction.
2)
In the above reaction left side of the reaction is considered as reactants.
- Trisodium phosphate
- Potassium hydroxide
3)
In the above reaction right side of the reaction is considered as products.
- Sodium hydroxide
- Potassium phosphate.

Answer : The temperature of the chloroform will be, 
Explanation :
First we have to calculate the mass of chloroform.
conversion used : 
Now we have to calculate the temperature of the chloroform.
Formula used :
where,
q = amount of heat or energy = 1.46 kJ = 1460 J (1 kJ = 1000 J)
= specific heat capacity = 
m = mass of substance = 110.958 g
= final temperature = ?
= initial temperature = 
Now put all the given values in the above formula, we get:
Now we have to convert the temperature from Kelvin to Fahrenheit.
The conversion used for the temperature from Kelvin to Fahrenheit is:
As we know that, 
or, 
...........(1)
Now put the value of temperature of Kelvin in (1), we get:
Therefore, the temperature of the chloroform will be,
