Answer: 44,8 l. of CO2 and 72 g. of water will be produced
Explanation:
Corrosion. Metals tend to form oxide and over time, they rust. ( 2 FeO(OH) ⇌ Fe2O3 + H2O). <span>Gold and platinum on the other hand are noble metals and remain stable in their pure form. Thus, no electron loss and no oxidation.</span>
PV = nRT
Pressure times volume = number of moles times ideal gas constant times temperature
50mL = .05L
1 atm (.05) = n (.0821) (273)
.05 = n (22.4133)
.022 = n (number of moles)
6.022E23 molecules = 1 mole
.022 x 6.022E23 = 1.325E23 molecules
Answer:
They are formed in the red bone marrow of bones.

Explanation:
The given cation:
(Rf₂Al₂F₃)³⁺
The oxidation number gives the extent to which a specie is oxidized in a reaction.
This number is assigned based on some rules:
- Elements in combined state whose atoms combines with themselves have an oxidation number of zero.
- The charge carried on simple ions gives their oxidation number.
- Algebraic sum of all the oxidation numbers of atoms in neutral compound is zero. In an ion with more than one kind of atom, the charge on it is the oxidation number.
for the specie given;
Known:
oxidation number of Al = +3
F = -1
charge = +3
let the oxidation number of Rf = k
2k + 2(3) + 3(-1) = +3
2k + 6 - 3 = 3
2k = 0
k = 0
The oxidation state of rutherfodium is 0
