<h3>
Answer:</h3>
52 g water
<h3>
Explanation:</h3>
In this question we are given;
Amount of heat, Q = 520 calories
Change in temperature, K = 10 K
We are required to calculate the mass of water.
Amount of heat is calculated by multiplying mass by specific heat capacity by change in temperature.
Q = m × c × Δt
The specific heat capacity,c of water = 1 Cal/g°C or 4.184 J/g°C
Rearranging the formula;
m = Q ÷ cΔt
= 520 Cal ÷ (1 Cal/g°C×10 K)
= 52 g
Thus, the mass of water sample is 52 g

Answer:
E) HBr
Explanation:
Because Bromine (Br) isn't part of the original formula for Apirin. (I answered this based on the assumption that the letter "A" in option C was a typo of sorts, since there is no element with a chemical symbol of just "A" that I am aware of. If this is incorrect, then I apologize.)
If a hypothesis is stated and outcome of the experiment is what was predicted, then it supports the hypothesis. if the experiment does not support the hypothesis, then the outcome was not what was predicted.
