The periodic table is arranged by various patterns. Is there a pattern with regard to ionic charge? In three to five sentences,
zlopas [31]

The oxidation number of elements becomes increasingly higher from left to right. Elements have more than one stable oxidation state as we move from left to right in the periodic table.

<h3>What does periodic table mean?</h3>

The periodic table, commonly known as the periodic table of elements, is set up so that scientists may rapidly determine an element's mass, number of electrons, electron configuration, and other distinctive chemical characteristics.

<h3>Why is the periodic table important?</h3>

All known elements are grouped together in the periodic table of elements into groups with related properties. It becomes a crucial tool for chemists, nanotechnologists, and other scientists as a result. You can forecast how chemicals will react if you learn to use and comprehend the periodic table.

A mixture of 14.0 grams of H2, 84.0 grams of N2, and 64.0 grams of O2 are placed in a flask. The partial pressure of the O2 is 7
Hitman42 [59]

Answer:

P_{tot}=465.27torr

Explanation:

Hello there!

In this case, according to the given information, it will be possible for us to use the Dalton's law, in order to solve this problem. However, we first need to calculate the mole fraction of oxygen by firstly calculating the moles of each gas:

n_{H_2}=\frac{14.0g}{2.02g/mol} =6.93mol\\\\n_{N_2}=\frac{84.0g}{28.02g/mol}=3.00mol\\\\n_{O_2}=\frac{64.0}{16.00g/mol}  =2.00mol

Next, we calculate such mole fraction as follows:

x_{O_2}=\frac{2}{6.93+3+2} =0.168

Then, given the following equation:

P_{O_2}=P_{tot}*x_{O_2}

So we solve for the total pressure as follows:

P_{tot}=\frac{P_{O_2}}{x_{O_2}} \\\\P_{tot}=\frac{78.00torr}{0.168} \\\\P_{tot}=465.27torr

Regards!
