Answer: 8855 Joules energy is released when 115 g of 
changes from a liquid to a solid at its freezing point.
Explanation:
Latent heat of freezing is the amount of heat released to convert 1 mole of liquid to solid at atmospheric pressure.
Amount of heat released to freeze 1 gram of = 77 J/g
Mass of given = 115 gram
Heat released when 1 g of is freezed = 77 J
Thus Heat released when 115 g of is freezed =
Thus 8855 Joules energy is released when 115 g of changes from a liquid to a solid at its freezing point.
I think the answer you have selected is right, I'm not sure tho
Answer:
C. As scientists have learned more about chemicals, they have become more aware of their dangers
Explanation:
Chemicals are substances with standard compositions, held together by chemical bonds. Chemicals can exist in different phases such as solid, liquid, and gaseous phases. Over time, with a growing understanding of chemicals, their composition, and their reaction methods, scientists now have a better knowledge of the dangers chemicals can pose. To that effect, they have created standard safety measures for those who have to work with these chemicals.
When these guidelines are strictly adhered to, the chances of suffering accidents, burns, and explosions with these chemicals are significantly reduced.
