Answer:

2. Components of a mixture can be separated by physical means

Explanation:

The Compound is defined as the substances that are chemically combined while mixtures are the substances in which two or more compounds are physically combined together.

The difference between compound and mixture from the given options is that mixture can be separated physically unlike compounds.

In a mixture, two or more compounds can be mixed in any proportion that can be separated by physical means. For example: salt from seawater (mixture) can be separated evaporation and nails from the mixture of sand and iron can be separated through magnetic separation.

Hence, the correct answer is "Components of a mixture can be separated by physical means".

1.1 Outline a method for separating the chalk from potassium chloride,
miss Akunina [59]

Answer:

Explanation:

To separate the a mixture of chalk and potassium chloride, we must not that chalk is calcium carbonate compound, CaCO₃.

Calcium carbonate has low solubility in water. KCl is readily soluble in water and it is also an ionic compound.

To separate a mixture of compounds with various solubility, we can carryout dissolution, filtration and evaporation.

We first pour pure water into the mixture. Water will dissolve the potassium chloride readily.

Then using a filter paper we filter out the suspended chalk particles. Leave the filtrate to then dry and collect it.

The solution filtered should be evaporated to dryness. This will leave the KCl behind from the solution.

what temperature change will be observed if a sample of 100 g of ethylene glycol antifreeze solution (specific heat capacity = 3
ivolga24 [154]

Answer:

1°C temperature change will be observed if a sample of 100 g of ethylene glycol antifreeze solution.

Explanation:

Mass of ethylene glycol = m = 100 g

Specific heat capacity of ethylene glycol = c = 3.5 J/g°C

Change in temperature of ethylene glycol = ΔT

Heat loss by the ethylene glycol = Q = 350 J

Q=mc\Delta T

\Delta T=\frac{Q}{mc}=\frac{350 J}{100 g\times 3.5 J/g^oC}

ΔT = 1°C

1°C temperature change will be observed if a sample of 100 g of ethylene glycol antifreeze solution.
