0cm3 of acid were mixed with 60cm3 of alkali in an insulated container. The average temperature of the two solutions before they

were mixed was 19.5°C. The temperature after mixing was 27.5°C. Was this an exothermic or an endothermic reaction?

Answer: Endothermic reaction.

Explanation: An endothermic reaction is any chemical reaction that absorbs heat from its environment. In this reaction, the temperature of the mixture raised from 19.5°C to 27.5°C, which means there was an increase of heat, ergo, it is an <u>endothermic</u> reaction.

What is the difference between sleet and hail? What conditions are needed to make each?
Furkat [3]

Answer:

Sleet forms in winter storms, while hail is a warm-season type of precipitation. As noted above, sleet forms when snow melts in a warm layer and then refreezes into ice pellets as it falls though a cold layer. Hail, however, forms in spring, summer or fall thunderstorms.

Drinking alcoholic or caffeinated beverages increases urine output more than drinking an equivalent amount of water.
olga2289 [7]

Answer:

A) ADH secretion decreases. B) Urine osmolarity decreases.

Explanation:

Antidiuretic Hormone or ADH is responsible for the reabsorption of water through the kidneys.

A) Drinking alcoholic and/or caffeinated beverages decreases the release and effect of ADH so the water does not get absorbed as much as it should, which in turn results in more urination.

B) Osmolarity is a term used to express the concentration of a solution in terms of a certain particle. Since less ADH secretion results in more water being in the urine, this lowers the concentration of the urine. So urine osmolarity would be decreased.

I hope this answer helps.

Aleks04 [339]

The correct answer is C. Gardeners choose which plants they let reproduced based on the plant traits.

Explanation:

In general, selective breeding involves the intervention of humans in the reproduction of species, this includes mainly plant and animal species. Moreover, in selective breeding, humans choose which specific species or individuals reproduce to favor certain traits. For example, a farmer might allow only the biggest cows to reproduce because this will lead to bigger calves. In this context, the option that shows selective breeding is C because this shows the intervention of humans in reproduction by selecting the individuals that will reproduce.
