Substance A and substance B are mixed together. To separate the mixture, water is added, and substance A is filtered out. Then,
Sveta_85 [38]

The correct answer would be that substance A is rice, and substance B is sugar.

For substance A to be filtered out, it means that A is a water-insoluble substance and for substance B to be recoverable by evaporating off the water, it means that B is water-soluble.

Thus, A can neither be sugar nor alcohol because neither can be recovered by filtration. Also, B can neither be coffee nor alcohol because they can not be recovered as residue through evaporation of water.

Therefore, the only correct answer is that substance A is rice, and substance B is sugar because rice can be filtered out from water while the water-soluble sugar can be recovered by evaporating the water.

Answer:

I believe the answer is A: Neveah's mass would stay the same but her weight would decrease

Explanation:

I believe its A because the moon has about 1/6 as much gravity as the Earth.  So if anything, her weight would decrease, not increase like B., C., or D says.  I hope this is helpful to anyone who reads it!!! ;)
