Answer:

Filtration is a method for separating an insoluble solid from a liquid. When a mixture of sand and water is filtered: the sand stays behind in the filter paper (it becomes the residue ) the water passes through the filter paper (it becomes the filtrate )

The following image shows the Atomic level of an element. In the image, which of
svp [43]

Answer:

D. The cation will use a type II naming system

Explanation:

As the element becomes stable, Option D is NOT taking place. That means that as the element becomes stable, the cation will NOT use a type II naming system. This is because in Type II binary compounds, the metal is not found in either Group 1 or Group 2 on the periodic table. It is as a result of this that the cation will not use a type II naming system.

Group 1 and Group 2 elements make use of type I naming system because in Type I binary compounds, the metal is present.

Option D is the correct answer.

Which of the following sample will have the greatest average speed at 355 K?. A. CH4. B. Ne. C. C2H4. D. Cl2
Amanda [17]

Answer:

The correct option is methane :CH_4.

Explanation:

Average speed of the gas molecules id given by expression:

v_{avg}=\sqrt{\frac{8kT}{\pi m}}

k = Boltzmann cosnatnt

T = Temperature of the gas molecules = 355 K

m = molecular mass of the molecule

v_{avg}\propto \sqrt{\frac{1}{m}}

Molar mass of methane = 18 g/mol

Molar mass of neon = 20.18 g/mol

Molar mass of ethene = 28 g/mol

Molar mass of chlorine gas = 70 g/mol

Lower the value of molar mass of gas molecule higher will be the average speed.So, from the given options methane gas greatest average seed because it has lowest molecular mass
