One method for preparing pure iron from Fe2O3 is by reaction with carbon monoxide.Fe2O3(s)+CO(g)→Fe(s)+CO2(g) How many moles of
larisa [96]

Answer:

The 2292 moles of CO are needed to react completely with 122 Kg of Fe₂O₃.

Explanation:

Given data:

Mass of Fe₂O₃ = 122 Kg ( 122×1000 =  122000 g)

Moles of CO = ?

Solution:

Chemical equation:

Fe₂O₃ + 3CO  → 2Fe + 3CO₂

Number of moles of  Fe₂O₃:

Number of moles = mass/ molar mass

Number of moles = 122000 g /159.69 g/mol

Number of moles = 764 mol

Now we will compare the moles of Fe₂O₃ with CO.

                               Fe₂O₃            :            CO  

                                  1                  :             3

                               764                :             3×764  =2292 mol

The 2292 moles of CO are needed to react completely with 122 Kg of Fe₂O₃.

Is KNO a strong acid?
stira [4]

Answer:

First of all, it's KNO₃ not KNO.

Second, KNO₃ is neither an acid nor it is a base, infact, it is a salt and therefore it's neutral.

hope that helps...

Can someone help me? We literally started this unit yesterday and I got quarantined so I dont have a clue what im doing..
zloy xaker [14]

Answer:

Explanation:

Take out your periodic table.

The choices that have one 1 member of the periodic table on it are elements.

He is the symbol for Helium

O2 oxygen

C3 but this is really odd. It is Carbon but Carbon usually does not  combine in 3s.

The rest are all compounds (they are made up of the elements on the periodic table). For example

H2SO4

is made up of 2 Hydrogens

1 sulfur

4 oxygens.

All the others do exactly the same thing.
