Answer: p orbitals only.

Carbon has an atomic number of 6 so its electron configuration will be 1s² 2s² 2p². It has two orbitals as indicated with the 2 as its period number with the outer orbital have 4 valence electrons. So carbon is in the p-orbital, period 2 and in group 4.

A 8L sample of gas at 250 K is cooled to 75 K. What is the volume of the gas after it is cooled?

Stells [14]

$by \: Charles'\: law: \: \\ \frac{v_{1}}{t_{1}} = \frac{v_{2}}{t_{2}} \\$

Where v is the volume(in L) and t is the temperature(in °K)

$\frac{8}{250} = \frac{v_{2}}{75} \\\\4/5 =v_2/3 \\\\\boxed{v_{2} = \frac{12}{5}}\\\\\\\huge{=2.5 l}$

How many molecules are there in 6.73 moles of phosphorus trichloride? (write your answer in scientific notation).

anyanavicka [17]

Answer: There are $4.05\times 10^{24}$ molecules in 6.73 moles of phosphorus trichloride

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number $6.023\times 10^{23}$ of particles.

1 mole of $PCl_3$ contains = $6.023\times 10^{23}$ molecules

Thus 6.73 moles of $PCl_3$ contains = $\frac{6.023\times 10^{23}}{1}\times 6.73=4.05\times 10^{24}$ molecules

Thus there are $4.05\times 10^{24}$ molecules in 6.73 moles of phosphorus trichloride
