Answer:

The chemical formula of the compound is $P_2O_5$ .

Explanation:

In 1 mole of $P_2O_x$ there are 2 moles of phosphorus atom.

Then 3.3 moles of phosphorus will be in :

$\frac{1}{2}\times 3.3 mol=1.65 moles$

In 1 mole of $P_2O_x$ there are x moles of oxygen atom.Then 1.65 moles of compound will have :

$1.65 mol\times x$

Moles of oxygen in 1.65 moles of compound = 8.20 mol

$1.65 mol\times x=8.20 mol$

$x=\frac{8.20 mol}{1.65 mol}=4.9 \approx 5$

The chemical formula of the compound is $P_2O_5$ .

Answer:

Oxygen in hydrogen peroxide oxidizes from -1 to 0.

Explanation:

Oxidation is the loss of electrons. The specie which is oxidized has has elevation in its oxidation state as compared in the reactant and the products.

The given reaction is shown below as:

$5 H_2O_2_{(aq)} + 2 MnO_4^-_{(aq)} + 6 H^+_{(aq)}\rightarrow 2 Mn^{2+}_{(aq)} + 8 H_2O_{(l)} + 5 O_2_{(g)}$

Manganese in $MnO_4^-$ has oxidation state of +7

Manganese in $Mn^{2+}$ has an oxidation state of +2

It reduces from +7 to +2

Oxygen in hydrogen peroxide has an oxidation state of -1.

Oxygen in molecular oxygen has an oxidation of 0.

Thus, oxygen in hydrogen peroxide oxidizes from -1 to 0.

Spell out the full name of the compound.

scoundrel [369]

Answer:

2–methylpropene.

Explanation:

To successfully name the compound given in the question, we must observe the following:

1. Determine the functional group of the compound.

2. Locate the longest continuous carbon chain. This gives the parent name of the compound.

3. Identify the substituent group attached and locate it's position by giving it the lowest possible count.

4. Combine the above to obtain the name of the compound.

Now, let us determine the name of the compound. This is illustrated below:

1. The functional group of the compound is the double bond i.e the compound is an alkene.

2. The longest continuous carbon chain is 3 i.e propene since it is an alkene.

3. The substituent group attached is methyl i.e CH3. In this case, we'll start counting from the side of the double bond being the functional group. Therefore, the methyl group i.e CH3 is at carbon 2.

4. Therefore, the name of the compound is:

2–methylpropene
