Answer:
he wants to explain why he started cooking
1) chromatography- separation by inner molecular attractions.
2) distillation- separation by boiling point differences.
3) filtration- separation by particle size
4) crystallization- separation by solubility
Entropy increases in reaction 1 due to increase in the number of particles while entropy decreases in reaction 2 due to decrease in the number of particles.
Entropy refers to the degree of disorderliness in a system. The higher the entropy, the more disorderly the system is and the lower the entropy, the less disorderly the system is. We must note that entropy increases with increase in the number of particles.
In the reaction, 2 KClO3 (s)⇌2 KCl (s)+3 O2 (g), entropy increases because one of the products is a gas and the number of particles increases from left to right. In the second reaction, CoCl2 (s)+6 H2O (g)⇌CoCl2⋅6H2O, entropy decreases because the number of particles decreases.

Answer:
I belive we are in climate change each year the earth gets closer to the sun and pollution from cars and factories cause the earth to warm up and cause pollution in our air. plastic is in the ocean, ice caps are melting, and the ocean is rising climate change is alredy here.
Answer:
Sorry if this is late but your answer is in the picture below,
Explanation:
If those boxes are touching they would transfer the same amount of heat and coolness that would evenly distribute the temperature.
Hence, the answer is the one on the very right top corner.
