Answer:
mass of water is 7.43 g
Explanation:
q = mc∆T
qsteam = 100 g × 1.864 J/(g °C) × (110 – 100) °C = 1864 J
qwater = mwater× 4.184 J/(g °C) × (95 – 35) °C = mwater× 251.04 J/g = qsteam = 1864 J
mwater = 1864 J / 251.04 J/g = 7.43 g
The question's incomplete unfortunately, which observations?
The following chemical reaction will occur:
Br₂ (l) + 2 NaI (s) → 2 NaBr (s) + I₂ (s)
Explanation:
Because the bromide (Br₂) have a higher reactivity than iodide (I₂) it is able the remove the iodide from its salts. So the bromide will react with sodium iodine (NaI) to produce sodium bromide (NaBr) and iodine.
The chemical reaction is:
Br₂ (l) + 2 NaI (s) → 2 NaBr (s) + I₂ (s)
where:
(l) - liquid
(s) - solid

The solubility curve is a plot of solubility against temperature.
<h3>What is solubility?</h3>
The term solubility refers to the amount of substance that dissolves in solution at a given temperature. Hence, the solubility curve is a plot of solubility against temperature.
Thus, from the solubility curve (not shown) the amount if HCl dissolved can be obtained hence the question is incomplete.
