Answer:
The final temperature of the water is 25.6 °C.
Explanation:
We have,
Heat added to water is 135.7 J
Mass, m = 54 g
Initial temperature was 25 °C
It is required to find the final temperature of the water. The heat added when temperature is increased is given in terms of specific heat capacity as :

is final temperature
c is specific heat capacity, for water, 
So,

So, the final temperature of the water is 25.6 °C.
Answer is: 25.84 milliliters of sodium metal.
Balanced chemical reaction: 2Na + 2H₂O → 2NaOH + H₂.
d(Na) = 0.97 g/mL; density of sodim.
m(NaOH) = 43.6 g; mass of sodium hydroxide.
n(NaOH) = m(NaOH) ÷ M(NaOH).
n(NaOH) = 43.6 g ÷ 40 g/mol.
n(NaOH) =1.09 mol; amount of sodium hydroxide.
From chemical reaction: n(NaOH) : n(Na) = 2 : 2 (1: 1).
n(Na) = 1.09 mol.
m(Na) = 1.09 mol · 23 g/mol.
m(Na) = 25.07 g; mass of sodium.
V(Na) = m(Na) ÷ d(Na).
V(Na) = 25.07 g ÷ 0.97 g/mL.
V(Na) = 25.84 mL.
Answer:
Rewrite the following sentence in reported speech
The chair person said,"A hearty welcome to all present!"
To segregate p-tert-butylphenol after you have removed it into NaOH arrangement one would accelerate the p-tert-butylphenol by adding 3M HCl to the cooled arrangement until the point when it is acidic. At that point as the phenol isolates as an oil, one needs to cool the blend in an ice shower to encourage crystallization. The precious stones that are then framed are the p-tert-butylphenol which can be isolated from the arrangement by filtration utilizing the Hirsch pipe
