The oxidation state of the compound Mn (ClO4)3 is to be determined in this problem.

For oxygen, the charge is 2-, the total considering its number of atoms is -24.

Mn has a charge of +3.

TO compute for Mn, we must achieve zero charge overall hence 3 + 3x - 24 = 0 where x is the Cl charge.

Cl charge, x is +7.

First, we'll calculate the valency of chlorine by using the net charge on the ClO₄ ion.
The ClO₄ ion has a charge of -1, while each oxygen atom exhibits a charge of -2. Therefore,

Cl + 4(-2) = -1
Cl = 7

Next, the valency of Mn is calculated by using the overall charge, which is 0

Mn + 3(-1) = 0
Mn = 3

Therefore, the valencies are:
Mn = 3
Cl = 7
O = -2

Alika [10]

Answer:

The hot water was better for removing the oil.

Explanation:

You can see that because the mass went down more with the hot water. So, that means that more oil was taken out of the feather with hot water.

Be sure to answer all parts. Propane (C3H8) is a minor component of natural gas and is used in domestic cooking and heating. (a)
Leokris [45]

<u>Answer:</u>

<u>For a:</u> The balanced chemical equation is given below.

<u>For b:</u> The mass of carbon dioxide produced will be 1.07\times 10^3g

<u>Explanation:</u>

  • <u>For a:</u>

Every balanced chemical equation follows law of conservation of mass.

This law states that mass can neither be created nor can be destroyed but it can only be transformed from one form to another form.

This law also states that the total number of individual atoms on the reactant side must be equal to the total number of individual atoms on the product side.

For the given reaction, the balance chemical equation follows:

C_3H_8(g)+5O_2(g)\rightarrow 3CO_2(g)+4H_2O(g)

All the substances are present in gaseous state.

  • <u>For b:</u>

By Stoichiometry of the reaction:

1 mole of propane gas produces 3 moles of carbon dioxide gas.

So, 8.11 moles of propane gas will produce = \frac{3}{1}\times 8.11=24.33mol of carbon dioxide gas.

Now, calculating the mass of carbon dioxide using equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}

Molar mass of carbon dioxide = 44 g/mol

Moles of carbon dioxide = 24.33 mol

Putting values in above equation, we get:

24.33mol=\frac{\text{Mass of carbon dioxide}}{44g/mol}\\\\\text{Mass of carbon dioxide}=1070.52g

Hence, the amount of CO_2 produced in the given reaction and expressed in scientific notation is 1.07\times 10^3g

Bob is investigating whether the density of water changes with temperature. Which of the following variables should he change in
LekaFEV [45]

Answer:

temperature of the water

Explanation:

Density is defied as mass divided by the volume. To investigate how the density of water change with temperature, Bob have the change the temperature and read the volume and mass of the investigated sample.

Even if there is a different salt content between booted water or tap water and have an influence on the density (compared with pure water), this difference is not so big so the change in density with temperature can be determined. Considering that the experiment do not require extreme accuracy,  any type of water may be used (bottled water of tap water).
