Answer:
45.45 ml of dimethyl sulfoxide
Explanation:
density of dimethyl sulfoxide is 1.10 g/10⁻³L which is 1.10 g/mL
now we devise the next reasoning:
If 1.10 g of dimethyl sulfoxide have a volume of 1 mL
Then 50 g of dimethyl sulfoxide have a volume of X mL
X = (50 × 1) / 1.10 = 45.45 ml of dimethyl sulfoxide
Answer:
C. Splitting the atom
Explanation:
splitting the atom involves fission
In order to obtain solid NaCl, the student should do a few steps.
First, he/she should do filtration. Pass the mixture through a filter paper, where all the sand should be filtered out already because they're not dissolved in the solution plus they're too small to pass through the filter paper.
Next, the filtrate should be left with NaCl (aqueous state). To seperate NaCl with the liquid, the student can either do evaporation or crystallization, depending on how pure or fast he/she wants the results to be. Evaporation involves heating the beaker or whatever apparatus under the bunsen burner until all the liquid has evaporated. Then, some white powder should be left, they're NaCl solid. For crystallization, the student should just put the beaker on a room condition environment, and wait. They might have to wait a month or so for the liquid to completely evaporate itself and left with clear and pure NaCl crystals.
