Carbon disulfide is prepared industrially by reacting carbon with sulfur dioxide according to the above equation. If 70.8 g of c

Rus_ich [418]

Answer:

1.18 moles of CS₂ are produced by the reaction.

Explanation:

We present the reaction:

5C + 2SO₂ → CS₂ + 4CO

5 moles of carbon react to 2 moles of sulfur dioxide in order to produce 1 mol of carbon disulfide and 4 moles of carbon monoxide.

As we do not have data from the SO₂, we assume this as the excess reagent. We convert the mass of carbon to moles:

70.8 g / 12 g/mol = 5.9 moles

Ratio is 5:1, so 5 moles of carbon react to produce 1 mol of CS₂

Then, 5.9 moles will produce (5.9 . 1) / 5 = 1.18 moles

The first four electrons shells fill out in what electron configuration?

Sidana [21]

Explanation:

2, 8, 8, 2 is the electron arrangement of Calcium.

The way that the "orbitals", the shells, fill up is given as

$1s^{2} 2s^{2} 2p^{6} 3s^{2} 3p^{6} 4s^{2} 3d^{10}$ . . . etc etc.

It is more stable for the fourth shell to start filling up with an electron pair, and then subsequent electrons filling up the third shell again.

So while potassium 19, is 2,8,8,1

And calcium 20, is 2,8,8,2

Scandium 21 will fill up as, 2,8,9,2

This will continue until we reach Zinc 30, which will fill up as 2,8,18,2. The third shell is now "full", and the fourth shell will now being to fill up.

The fourth orbital starts getting filled up again, Gallium 31, is 2,8,18,3

Fe(NO3)2 not sure how to get the oxidation numbers of all elements

SOVA2 [1]

Fe(NO3)2=0
Fe+2(+3+3*-2)=0
Fe+2*-3=0
Fe=-(-6)
Fe=+6

So, Fe=+6, N=+3, O=-2
