Answer: Option (B) is the correct answer.

Explanation:

Good conductors are defined as the substance through which heat can effectively pass.

For example, copper, and iron are good conductors of heat and electricity.

Generally, metals are good conductors of heat as well as electricity.

On the other hand, bad conductors are the substances through which heat is unable to flow.

For example, glass, wood, foam etc are all bad conductors of heat as well as electricity.

Thus, we can conclude that out of the given options copper and iron are good conductors of heat.

Answer: Option (B) is the correct answer.

Explanation:

Metals are the substances that have more number of electrons. Metals are good conductors of heat and electricity.

For example, iron, copper, zinc are all metals and good conductors of heat and electricity.

Whereas wood and foam are is a poor conductor of heat and electricity.

Thus, we can conclude that out of the given options copper and iron are good conductors of heat.

Match each alkane names and structures.
Scilla [17]

First structure is  CH₃-CH₃. It is an alkane with two carbon atoms hence it is called ethane.

Second structure is  CH₃-CH₂-CH₂-CH₃. It is an alkane with four carbon atoms hence it is called butane.

Third structure is CH₄. It is an alkane with one carbon atom hence it is called methane.

Fourth structure is CH₃-CH₂-CH₃. It is an alkane with three carbon atoms hence it is called propane.

A chemical test has determined the concentration of a solution of an unknown substance to be 2.41 M. a 100.0 mL volume of the so
Oksana_A [137]

Answer : The molar mass of unknown substance is, 39.7 g/mol

Explanation : Given,

Mass of unknown substance = 9.56 g

Volume of solution = 100.0 mL

Molarity = 2.41 M

Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.

Formula used :

\text{Molarity}=\frac{\text{Mass of unknown substance}\times 1000}{\text{Molar mass of unknown substance}\times \text{Volume of solution (in mL)}}

Now put all the given values in this formula, we get:

2.41M=\frac{9.56g\times 1000}{\text{Molar mass of unknown substance}\times 100.0mL}

\text{Molar mass of unknown substance}=39.7g/mol

Therefore, the molar mass of unknown substance is, 39.7 g/mol
