Reaction sequence:
2c(s) + o2(g) -> 2co(g)
fe3o4(s) + 4co(g) -> 3fe(l) + 4co2(g)
According to first equation, 2 moles of carbon produce 2
moles of carbon monoxide. So 1 mole of carbon will produce 1 mol of carbon
monoxide (the same number).
According to the second equation, 4 moles of carbon monoxide
produce 3 moles of iron. We should make the cross multiplication with those
numbers:
4 moles CO/3 moles iron = 1 mol CO/x
x = 1 mol CO*3 moles iron/4 moles CO = 0.75 moles of iron
You'll want to convert meters to inches, right? Well, you know that 2.54 centimeters make 1 inch.
And you know that 100 cm make one meter.(100 m)(100cm/1m)(1 inch/2.54 cm)
Answer:
where is the question
Explanation:
give the question and then I'll make answer your question
Answer:
Explanation:
1. Convert Atoms to Moles
To convert atoms to moles, we use Avogadro's Number: 6.022*10²³. This tells us the amount of particles in 1 mole of a substance. In this case, it is atoms of silver.
Multiply by the given number of atoms.
Flip the fractions so the atoms of silver cancel.
2. Convert Moles to Grams
To convert from moles to grams, we use the molar mass. This can be found on the Periodic Table.
- Silver (Ag): 107.868 g/mol
Use this as a fraction.
Multiply by the number of moles we calculated. The moles of silver will cancel.
Answer:
Fe + CuO ----> FeO+ Cu
Explanation:
A word equation is a chemical equation in which the reactants and products are represented by words rather than the respective symbols of the species involved in the reaction.
Generally, when writing a balanced reaction equation, it is normal to ensure that the number of atoms of each element on the reactant side is the same as the number of atoms of the same element on the product side. This has been ensured in the reaction above.
The reaction above is possible because iron is higher than copper in the electrochemical series hence iron can displace copper from its compounds.
