A beaker contains a mixture of sand and salt. A student adds water to dissolve the salt. Which processes can be used to separate out the sand and salt?(1 point)

Question

Responses

filtration to collect the sand and distillation to collect the salt
filtration to collect the sand and distillation to collect the salt

distillation to collect the sand and filtration to collect the salt
distillation to collect the sand and filtration to collect the salt

filtration to collect both the sand and the salt
filtration to collect both the sand and the salt

distillation to collect both the sand and the salt

Answer 1

The correct response is:

filtration to collect the sand and distillation to collect the salt

In this process, filtration is used to separate the solid sand from the liquid solution containing dissolved salt. The sand will be trapped by the filter, while the salt solution passes through. After that, distillation can be used to evaporate the water from the salty solution, leaving the salt behind.

Answer 2

Which phases does water go through if you use distillation to separate it from dissolved sugar?(1 point)
Responses

from a liquid to a solid, and then to a gas
from a liquid to a solid, and then to a gas

from a liquid to a gas, and back to a liquid
from a liquid to a gas, and back to a liquid

from a liquid to a solid, and back to a liquid
from a liquid to a solid, and back to a liquid

from a solid to a liquid, and then to a gas

Answer 3

The correct response is:

from a liquid to a gas, and back to a liquid

In distillation, the sugar solution is heated, causing the water to evaporate and transition from a liquid to a gas. The vapor is then cooled and condensed back into a liquid, separating it from the dissolved sugar.
