Answer: 317 joules
Explanation:
The quantity of heat energy (Q) gained by aluminium depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)
Thus, Q = MCΦ
In this case,
Q = ?
Mass of aluminium = 50.32g
C = 0.90J/g°C
Φ = (Final temperature - Initial temperature)
= 16°C - 9°C = 7°C
Then, Q = MCΦ
Q = 50.32g x 0.90J/g°C x 7°C
Q = 317 joules
Thus, 317 joules of heat is gained.
Add an alkaline compound to raise the pH to 7.2.
Answer:
<h3>The answer is 320.75 mL</h3>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
![volume = \frac{mass}{density} \\](https://tex.z-dn.net/?f=volume%20%3D%20%20%5Cfrac%7Bmass%7D%7Bdensity%7D%20%20%5C%5C%20)
From the question we have
![volume = \frac{340}{1.06} \\ = 320.7547169...](https://tex.z-dn.net/?f=volume%20%3D%20%20%5Cfrac%7B340%7D%7B1.06%7D%20%20%5C%5C%20%20%3D%20320.7547169...)
We have the final answer as
<h3>320.75 mL</h3>
