No of protons=No of electrons=15

<h3>Mass no:-No of neutrons+No of protons </h3>

$\\ \tt\longmapsto 15+16=31$

Now

It has atomic no 15 hence its Phosphorus(P)

Electronic configuration:-

$\\ \tt\longmapsto 1s^22s^22p^63s^23p^3$ .

Valency=3

Chloride formula:-

$\\ \tt\longmapsto XCl_3$

or.

$\\ \tt\longmapsto PCl_3$

How do I identify significant figures in chemistry?

Komok [63]

1) START counting for sig. figs. On the FIRST non-zero digit.

2) STOP counting for sig. figs. On the LAST non-zero digit.

3) Non-zero digits are ALWAYS significant.

4) Zeroes in between two non-zero digits are significant. All other zeroes are insignificant.

How many moles are in 12 liters of Cl2?

RoseWind [281]

Answer:

$\boxed {\boxed {\sf 0.54 \ mol \ Cl_2}}$

Explanation:

A mole is any quantity of a substance that contains 6.02 × 10²³ particles. At standard temperature and pressure, or STP, 1 mole of as is equal to 22.4 liters. This is true for any gas, regardless of the specific kind.

Although it is not specified, we can assume this gas is at STP. Let's set up a ratio using this information: 22.4 L/mol

$\frac {22.4 \ L \ Cl_2}{1 \ mol \ Cl_2}$
