To go from molecules to moles divide by Avogadro's number [<span>6.02x10^23]</span>
Example:
1.50x10^23 divided by 6.02x10^23 = 0.249 moles rounded to three significant figures
According to Le Chatelier's principle, adding additional reactant to a system will shift the equilibrium to the right, towards the side of the products. ... By Le Chatelier's principle, we can predict that the amount of methanol will increase, thereby decreasing the total change in CO.
Answer:
Sulfur reacts with oxygen to form sulfur dioxide. When nonmetals reactwith one another, the product is a molecular compound. Often, the nonmetal reactants can combine in different ratios and produce different products. Sulfur can also combine with oxygen to produce sulfur trioxide.
Answer:
C
Explanation:

are used up to produce 6
Answer:
B. A chemical formula that shows the relative number of each type of
atom in a molecule, using the smallest possible ratio
Explanation:
The empirical formula of a compound shows the relative number of each type of atom in a molecule and it uses the smallest possible ratio.
- It expresses the composition of the compound in the simplest whole number ratio of the atoms of the different elements that makes up the compound.
- To determine empirical formula of a compound , two pieces of information are needed;
- A. mass of each element in the compound
- B. Relative atomic mass of the constituent elements.
