3.) Charge on one molecule of PO4 is -3. So on two molecule it'll be 2(-3) = -6. Let oxidation number of Pb be x. Therefore, 3x+(-6) = 0. 3x=6. x=2.
<span>First we write the reactants and the products in this manner shown below:
C5H12 + O2 = H20 + CO2
This equation is not yet balanced so we add coefficients to make the equation balance:
</span><span>C5H12 + 8O2 = 6H20 + 5CO2
</span>
The principle of concern here is the Law of Conservation of Mass.
<span>This law states that for a system that is isolated, the mass is not created nor destroyed. Hence for this system, the amount of CO2 and water created is exactly from the reactants pentane and oxygen.

Electrons are transferred from one reactant to another and the oxidation states/oxidation number of certain atoms are changed
<u>Answer:</u> The concentration of ions is 0.10 M and that of ions is 0.30 M
<u>Explanation:</u>
We are given:
Concentration of = 0.10 M
The chemical equation for the ionization of aluminium bromide follows:
1 mole of aluminium bromide produces 1 mole of aluminium ions and 3 moles of bromide ions
So, concentration of aluminium ions = 0.10 M
Concentration of bromide ions =
Hence, the concentration of ions is 0.10 M and that of ions is 0.30 M
Plasma has a neutral charge, as well as the same amount of protons and electrons put together. if the question has only one answer then it is plasma.
