Which of the following is not true about chemical changes? a. They form a new substance. b. They can be reversed by physical cha
Sonbull [250]

Answer: The correct option is b.

Explanation: Chemical reaction is a reaction i which the chemical composition of the reactants gets changed and new substances having different chemical composition is formed. This reaction cannot be reversed by any physical means.

Indicators showing chemical changes are :

  • Color change
  • Characteristic odor
  • Formation of bubbles
  • Formation of precipitate

From the given information above, it can be stated that the correct option is b.

What solutes are soluble in water?
marusya05 [52]

Answer:

Ionic compounds, such as sodium chloride, are also highly soluble in water. Because water molecules are polar, they interact with the sodium and chloride ions. In general, polar solvents dissolve polar solutes, and nonpolar solvents dissolve nonpolar solutes.

Of the following gases, ________ will have the greatest rate of effusion at a given temperature. Of the following gases, _______
kolezko [41]

<u>Answer:</u> From the given gases, the greatest rate of effusion is of CH_4

<u>Explanation:</u>

Rate of effusion of a gas is determined by a law known as Graham's Law.

This law states that the rate of effusion or diffusion of a gas is inversely proportional to the square root of the molar mass of the gas. The equation given by this law follows:

\text{Rate of diffusion}\propto \frac{1}{\sqrt{\text{Molar mass of the gas}}}

It is visible that molar mass is inversely related to rate of effusion. So, the gas having lowest molar mass will have the highest rate of effusion.

For the given gases:

Molar mass of NH_3=17g/mol

Molar mass of HCl=36.5g/mol

Molar mass of CH_4=16g/mol

Molar mass of Ar=40g/mol

Molar mass of HBr=81g/mol

The molar mass of methane gas is the lowest. Thus, it will have the greatest rate of effusion.

Hence, the greatest rate of effusion is of CH_4
