Answer:
From the diagram, the water is being boiled. This process vaporises the water in the vessel leaving salt crystals behind.
Since the water is needed in liquid form, the cold water at the top of the set-up
condenses the vapor so it can be used.
Answer:
B
Explanation:
well heterogenous mixtures are not uniformly distributed these meaning whatever components are "mixed" can be seperated easily
a example of this can be
Soil, oil in water, ice in water
while Homogeneous mixture cannot be seen seperated
The choices can be found elsewhere and as follows:
a. mass-mass problems
<span>b. mass-volume problems </span>
<span>c. mass-particle problems </span>
<span>d. volume-volume problems
</span>
I believe the correct answer is option D. It is volume-volume problems that does not require the use of molar mass. <span> Here you are dealing with molarities and volumes to determine concentrations. Molar mass is not part of any calculations.</span>
The structure of Dimethyl sulfide is H3C-S-CH3. It is produced naturally by some marine algae.
<u>Explanation:</u>
- DMS or dimethyl sulfide is formed by using two methyl groups combined with one sulfur atom. It is an organosulphur compound with a structural formula H3C-S-CH3.
- Most abundant biological sulfur compounds emitted to air and oceans by phytoplankton.
- DMS is produced naturally by the waste of dimethyl sulphoxide which is disposed into the sewer causing environmental odor problems.
- It is a flammable liquid that boils at 37 degrees celsius and a disagreeable smell produced from the cooking of certain vegetables also indicates bacterial contamination in the production of malt and brewing.
Salts is the correct awnser
