Answer:
Cr2O3 and 3C are the reactants
2Cr and 3CO are the products
Explanation:
Cr2O3is reacting with 3C to form 2Cr + 3CO
Not necessarily at all
Having the same volume means that these 2 objects occupy the same amount of space but it does not at all mean that these 2 objects have to be of an equal amount of mass
An example to simplify it is how you can fill a box with 100 little balls but it will require you millions of sand particles to fill the same box
In both cases the volume of the box which the 2 objects occupy is the same but the amount of basic units so to speak is different for sure
This simplification goes further in depth when looking at the atomic infrastructure of matter, objects like those of yours in the question
A Mole of whatever the matter may be, however, has the same amount of mass and this is due to the fact that the Mole is related to the definite <span>Avogadro's number, number of units in one mole of any substance (defined as its molecular weight in grams), equal to 6.022140857 × 10</span>²³<span>. </span>
Hi , bacteria is the answer.

There are eight moles of oxygen atoms in 1 mole of 
.
<h3>What is the number of moles of oxygen atoms?</h3>
We know that a compound is composed of atoms. The atoms that make up the molecule are chemically combined. It is usual that the number of atoms in the compound would correspond with the chemical formula.
Now we have the compound . In one mole of the compound we have;
- 9 Moles of manganese atom
- 2 moles of chlorine atom
- 8 moles of oxygen atom
Thus, there are eight moles of oxygen atoms in 1 mole of .
