Answer:

A) Separating funnel method

B) Simple Distillation

C) Evaporation

D) Sublimation

E) It is based on the principle of separation whereby even though two substances are dissolved in the same solvent, their respective solubilities could be different. Thus, the component that has more solubility will rise fastest and will therefore get separated from the mixture.

Explanation:

A)

B) Kerosene and petrol are both miscible liquids and the difference in their boiling point temperature is not more than 25°C. Thus, we make use of Simple distillation.

C) Can be separated by evaporation where the water is boiled and it evaporates and leaves the salt behind

D) To separate camphor from salt, we use sublimation so the camphor can change directly from solid to the gas state without passing through the liquid state.

E) Chromatography is used to separate components of a mixture.

It is based on the principle of separation whereby even though two substances are dissolved in the same solvent, their respective solubilities could be different. Thus, the component that has more solubility will rise fastest and will therefore get separated from the mixture.

A solution of diamminesilver(I) chloride is treated with dilute nitric acid. What products you get? [Ag(NH3)2]Cl(aq) + HNO3(aq)
Anit [1.1K]
The reaction is a double displacement one which means the cation of one reactant is substituted  to the cation of the other reactant to identify the products. Hence in this reaction, the products are silver ammonium nitrate (Ag(NH3)2NO3) and hydrochloric acid (HCl).

Gaseous neon has a density of 0.900 g/L at standard conditions. How many neon atoms are in 1.00 L of neon gas at standard condit
Anvisha [2.4K]

Answer: 1.348 ×10^23 atoms

Explanation:

Given that volume = 1.00L

At standard condition, the volume of a gas is 22.4L/mol (at S.T.P)

Volume = mole /volume at STP

1 = mole/22.4

Mole= 22.4mol.

Also

Mole = number of atoms /Avogradro constant

Where avogrado's constant = 6.02×10²³

22.4 = number of atoms/6.02×10²³

Number of atoms = 1.348×10^25atoms

A certain solution is 70% ethanol and the rest being distilled water. If there are 12 moles of ethanol per litre of solution, fi
Aleks04 [339]

Answer:

0.55284g/mL

Explanation:

Hello there!

In this case, given the by-mass percent of ethanol:

\frac{70gEt}{100gSol}

It is possible to compute the density by using its molar mass to find the grams in one liter of solution:

12\frac{molEt}{1L}*\frac{46.07 gEt}{1molEt}=552.85g/L

However, by taking the g/mL we obtain:

552.84\frac{g}{L} *\frac{1L}{1000mL}=0.55284g/mL

Which is the density of the solution.

Best regards!
