Answer:

Electrons are the smallest of the particles that make up an atom, and they carry a negative charge. The number of protons and electrons is equal in a neutral atom. The hydrogen atom, for example, has just one electron and one proton. The uranium atom, on the other hand, has 92 protons, and therefore, 92 electrons.

Trava [24]

Answer : The volume of gas will be, 113.5 L

Explanation :

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

where,

$P_1$ = initial pressure of gas = 60 atm

$P_2$ = final pressure of gas = 30 atm

$V_1$ = initial volume of gas = 29 L

$V_2$ = final volume of gas = ?

$T_1$ = initial temperature of gas = 115 K

$T_2$ = final temperature of gas = 225 K

Now put all the given values in the above equation, we get:

$\frac{60atm\times 29L}{115K}=\frac{30atm\times V_2}{225K}$

$V_2=113.5L$

Therefore, the volume of gas will be, 113.5 L

Draw the structures of all monofluoro derivatives of methylcyclopentane, c6h11f, which have the fluorine on a primary carbon.

STatiana [176]

Answer: There are 4 monofluoro derivatives of methylcyclopentane. Only 1 derivative has flourine atom attached to a primary carbon.

Explanation: The compound methylcyclopentane has 1-primary carbon, 4- secondary carbons and 1-tertiary carbon.

1) Primary carbon (1°): In this the carbon atom is attached directly to only one carbon atom.

2) Secondary carbon (2°): In this the carbon is attached directly to two carbon atoms.

3) Tertiary Carbon (3°): In this the carbon is attached directly to three carbon atoms.

The monofluoro derivatives are shown in the image below.

Structure B is the only derivative which has fluorine attached to primary carbon atom.
