Answer:
Advantages :they are used for seeing chemical reactions .
they are used for doing chemical experiment .
they are used for making affective medicines .
Disadvantages :they harms to our environment.
they can make side effects in our body by affective medicines made by chemicals.
while doing different unknown experiments they make explosions which can also harm to us.
I think the answer would be dependent variable. An unknown or changeable quantity is called a dependent variable. It <span>is what you measure in the experiment and what is affected during the experiment. Hope this answers the question. Have a nice day.</span>

Energy lost to condense = 803.4 kJ
<h3>Further explanation</h3>
Condensation of steam through 2 stages:
1. phase change(steam to water)
2. cool down(100 to 0 C)
1. phase change(condensation)
Lv==latent heat of vaporization for water=2260 J/g

2. cool down
c=specific heat for water=4.18 J/g C

Total heat =
