Answer:

Yes

Explanation:

4Fe+3O2

4Fe

3O2

So therefore 6 Oxygen atoms

2Fe2

2x2

Therefore 4 Iron atoms

2O3

2x3

Therefore 6 Oxygen atoms

Nadusha1986 [10]

Answer:

electrons fill lower energy levels first before occupying higher energy levels.

Explanation:

The Aufbau's principle describes that electrons fill lower energy levels first before occupying higher energy levels.

In writing the electronic configuration of atoms, the Aufbau's principle is one of the most important principles to consider.

It states that "sublevels with with lower energies are filled up before those with higher energies".

Sublevels do not fill up in numerical order.

If you had an object with a mass of 76g and a volume of 22 ml, what is its density? If you cut this object in half, what would b
V125BC [204]
D = M/V = 76g / 22ml = 3.4g/ml

Half ~ D = 38g / 11ml = 3.4g/ml

Even if the object you had was cut in half, it’s density would remain the same.

which atom has a change in oxidation number of -3 in the following redox reaction K2Cr2O7 + H2O +S --&gt; KOH + Cr2O3 +SO2
yaroslaw [1]
You have to calculate the oxidation estates of the atoms in each compound.

I will start with K2Cr2O7 because I believe that Cr is the best candidate to reduce its oxidation number in 3 units.

In K2Cr2O7:

- K has oxidation state of 1+, then K2 has a charge of 2* (1+) = 2+.

- O has oxidation state of 2*, then O7 has a charge of 7* (2-) = 14-.

That makes that Cr2 has charge of 14 - 2 = +12, so each Cr has +12/2 = +6 oxidation state.

In Cr2O3:

- O has oxidation state of 2-, then O3 has charge 3 * (2-) = - 6

- Then, Cr2 has charge 6+, and each Cr has charge 6+ / 2 = 3+.

So, we have seen that Cr reduced its oxidation state in 3 units, from 6+ to 3+.

Answer: Cr has a change in oxidation number of - 3.
