Added together = 159.7 grams for one mole of Fe2O3<span>. That is moles of hematite, but the question is about iron. We can see there are </span>two<span> iron atoms for every hematite molecule. So the number (moles) of iron atoms is twice the moles of the hematite molecules.
so depending on how much you initially have will determine the answer</span>
Ask your lab manager for instructions. If you happen to be the lab manager, take out the container (making a note of where it is), find the culprit, and try to figure out what might be in the beaker so you can know how to properly dispose of it.
Proper safety measures should be followed.
<h2>
What are the safety measures in chemistry lab?</h2>
In the lab, always use the proper eye protection, such as chemical splash goggles. When handling hazardous items, put on the disposable gloves that the laboratory has given. Before leaving the lab, take the gloves off. Put on a full-length, long-sleeved lab coat (apron) or apron that can withstand chemicals.

The chemical formula CH2O can be classified as Empirical formula and possibly a molecular formula. The empirical formula of a compound is the simplest formula that indicates the simplest ratio of atoms in the compound, while the molecular formula is the representation of the actual whole number ratio between the elements of the compound.
<span>CO2 (carbon) is the main product that results from burning paper. The paper is the reactant
When paper burns in a fire, the reactants are mostly carbon (the main substance in the paper) and oxygen (from the air).Co2
If paper is loaded with CaCO3 such as cigarette paper, CaCO3 decompose in to CaO and CO2</span>
