Ere are two parts to a chemical equation. The reactants are the elements or compounds on the left side of the arrow (-->). The elements and compounds to the right of the arrow are the products.
Answer:
A
Explanation:
that should be the answer
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.

Answer:

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:

Next, we calculate such mole fraction as follows:

Then, given the following equation:

So we solve for the total pressure as follows:
