Chlorine.

If you search Google images for "Aufbau principle periodic table," you'll find some handy diagrams that will make it much easier to determine an element based on its electron configuration. Determine the number of electrons in the last part of the configuration (in this case, 5), locate that group on the Aufbau periodic table diagram, then count that number from left to right within that group. In this case, within the "3p" portion of the Periodic table, count to 5 and you'll find Chlorine as the answer.

Explanation:

In chemistry, a chemical formula is a scientific notation to show the chemical proportion of atoms that represents a particular compound or molecule. The empirical formula of a chemical compound illustrates the simplest whole number ratio between the elements contained in the compound whereas the molecular formula is the representation of the actual whole number ratio between each element of the compound.

Given that the empirical formula of carbamide is \text{CH}_{4}\text{N}_{2}\text{O}, then, the corresponding molecular weight (M_{r}) is

                                 M_{r} \ = \ 12 \ + \ 4(1.008) \ + \ 2(14) \ + \ 16 \\ \\ M_{r} \ = \ 60.032 \ \text{g mol}^{-1}.

Subsequently, using the relation

                      n \ \times \[M}_{r}(\text{empirical formula})] \ = \ M_{r}(\text{molecular formula}),

where n is the multiple of empirical formula unit.

Therefore,

                                             n \ = \ \displaystyle\frac{M_{r}(\text{molecular formula})}{{M}_{r}(\text{empirical formula})} \\ \\ n \ = \ \displaystyle\frac{60 \ \text{g mol}^{-1}}{60.032 \ \text{g mol}^{-1}} \\ \\ n \ = \ 1

A gas has pressure of 50.0 mmHG at a temperature of 540K. What will be the temperature if the pressure goes down to 3 mmHG
Sonja [21]

Answer:

32.4 K

Explanation:

From the given parameters;

Initial pressure P1= 50.0 mmHg

Initial temperature T1= 540K

Final Temperature T2 = ?????

Final pressure P2=3 mmHg

Now using this relationship;

P1/T1 = P2/T2

We have; P1T2= P2T1

Hence;

T2= P2T1/P1

T2= 3 ×540/50.0

T2= 32.4 K
