Correct compound is [Co(H2O)6]^+3
The oxidation state of Co is +3
[Co(H2O)6]^+3
Let
Co be x
H2O = 0
x + (0)6 = 3
x = 3
What is oxidation state?
The oxidation state, commonly known as the oxidation number, is the potential charge that an atom would have if all of its bonds to other atoms were fully ionic. It describes the degree of atom oxidation within a chemical compound.The oxidation state may be positive, negative, or zero in theory.
The oxidation number, sometimes referred to as the oxidation state, is the total number of electrons that an atom gains or loses while uniting with another atom to form a chemical bond.

Answer:
Al2(SO4)3 -> Al2O3+3SO3
Explanation:
No need of much explanation
During the time balancing the equations just see the no. of atoms on either side of the reaction I.e the reactant and product side make them equal by multiplying with some integers that's it!!
Answer:
AgNO3 + NaOH = AgOH + NaNO3.
Explanation:
<em><u>Balancing Strategies: In this reaction, the products are initially NaNO3 + AgOH. However the AgOH would break down into Ag2O and H2O. This would give us NaNO3 + Ag2O + H2O as our products for the overall reaction.</u></em>

Answer:

Explanation:
Hello,
In this case, for the calculation of the half-life for the mentioned reaction we first must realize that considering the units of the rate constant and the form of the rate law, it is a second-order reaction, therefore, the half-life expression is:
![t_{1/2}=\frac{1}{k[A]_0}](https://tex.z-dn.net/?f=t_%7B1%2F2%7D%3D%5Cfrac%7B1%7D%7Bk%5BA%5D_0%7D)
Therefore, we obtain:

Answer:
d
Explanation:
d. 1000.00 The fact that there is a decimal point is a sinal that the measurement was made down to past the ones position. The 2 additional zeros signal that it was measured down to the hundreths position.
