I don't know if I'm correct but I think it's A or C you don't have to choose them.
Answer:
Sodium
Explanation:
Sodium is a pure chemical, hence it can be represented by the single chemical symbol Na.
Water has a chemical symbol of H2O, consisting of two, and not one, symbols, H and O.
Sulfate ion consists of a sulfide ion and four oxygen ions (SO4)2-. Hence, it does not fit.
Finally, potassium chloride has a chemical symbol of KCl. Consisting of two different chemical symbols, (K and Cl), it does not fit either.
Hope this helped!
Here,
Heat gain by the first sample of water + Heat lost by the second sample of water is equal to zero (0).
Now, Mass of water sample one = 108 g (given)
Mass of water sample two = 66.9 g (given)
Temperature for water sample one =
Let, temperature for water sample two =x
And, final temperature =
Now,
where, = final temperature
= initial temperature
Substitute all the given values in above formula:
[tex x =84.81^{0}C [/tex]
