Answer is: an instant ice pack becoming cold, splitting a gas molecule and baking bread.
<span>Endothermic reaction
is chemical reaction that absorbs more energy than it releases.
</span>In ice pack, <span>reaction absorbs heat from the surroundings (endothermic reaction), lowering the surrounding temperature.
For splitting molecule and baking bread we must add energy to break bonds between atoms.</span>
Answer:
1/360
Explanation:
let x = liters
molarity=moles of solute/liters of solution, 7.2=0.02/x or 7.2=(1/50)(1/x), 7.2(50)=(1/x), 360(x)=1, x=1/360

To develop a deeper understanding, students need to investigate the context of the time in which science ideas were developed.
Explanation:
Answer:
1.Difference.
Mixtures are physically combined and can be separated by physical means while compounds are chemically combined and are separated by chemical means.
2.Mixtures do not have mixed boiling and melting points while compounds have mixed boiling and melting points.
2.Similarity.
Both mixtures and compounds are composed of two or more substances or elements combined.
Both can be separated.
