Answer:
Q = 9460 Kj
Explanation:
Given data:
Mass of copper = 2kg
Latent heat of vaporization = 4730 Kj/Kg
Energy required to vaporize 2kg copper = ?
Solution:
Equation
Q= mLvap
It is given that heat required to vaporize the one kilogram copper is 4730 Kj thus, for 2 kg
by putting values,
Q= 2kg × 4730 Kj/Kg
Q = 9460 Kj
O, C, Ga, K, Cs is the correct order from lost to least

C=2.55
Ga=1.81
K=0.82
Cs=0.79
The answer is D: There is life on some other planet in the universe aside from earth
<span>The reasons to use insoluble salts to soften water would be to make the water more potable, and to enable better sudsing when washing clothes, dishes, or for taking showers.
Hard water tends to decay pipes at a faster rate, leave deposits on sinks, tubs, and toilets.
Hard water has a high percentage of calcium and other minerals that have an unpleasant taste and will often cause the joints between pipes to start leaking much much sooner than they would otherwise.</span>
