Answer:

78.89 g of CO is required.

Explanation:

Fe_{2}O_{3}+3CO\longrightarrow3CO_{2}+2Fe

Fe = 55.85 g/mol

O = 15.99 g/mol

C = 12.01 g/mol

2 moles of Fe is produced on reacting 1 mole of Fe_{2}O_{3}.

2 moles of Fe is produced on reacting 3 moles of CO.

Weight\:of\:one\:mole\:of\:Fe_{2}O_{3}=2\times55.85+3\times15.99=159.67g\\

Weight\:of\:one\:mole\:of\:CO=12.01+15.99=28g

The\:weight\:of\:two\:moles\:of\:Fe=2\times55.85=111.7g\\111.7g\:of\:Fe\:is\:produced\:by\:reacting\:(3\times28=)84g\:of\:CO\\\\104.9g\:of\:Fe\:is\:produced\:on\:reacting=\frac{84\times104.9}{111.7}=78.89g\:of\:CO\\

Hence, 78.89 g of CO on reacting with excess of ferric oxide will produce 104.9 g of Fe.

How many moles of NF3 are present in a sample that contains 8.02 moles of a Fluorine atom
Ad libitum [116K]

Hey there!

The sample of NF₃ contains 8.02 moles fluorine atoms.

There are 3 fluorine atoms in each molecule, so there will be 1/3 of the moles of fluorine.

8.02 / 3 = 2.67

There are 2.67 moles of NF₃ in a sample that contains 8.02 moles fluorine atoms.

Hope this helps!

What is the mole ratio of NH3 to N2?
Ksenya-84 [330]
To answer this question a balanced chemical equation is necessary. The correct equation is: N2 + 3H2 = 2NH3
From this equation, one mole of nitrogen react with 3 moles of hydrogen to give 2 moles of ammonia.
Therefore, the mole ratio of NH3 to N2 is 2:1

Chlorine (CI) can be found as an ion with a 1- charge. How does this happen?
Lesechka [4]

Answer:There are 18 electrons and 17 protons, so the chlorine atom has become a charged chlorine ion with a charge of negative one (-1). ... When it does, the sodium atom becomes a sodium ion with a charge of positive one (+1). Chlorine, as mentioned above, desperately wants an electron so it can fill its outer electron level.
