Answer:

[OH-] = 0,071 mol/L

Explanation:

pOH = -log[OH-]

[OH-] = 10^-pOH = 10^-1.15 = 0,071 mol/L

What is the chemical formula for Copper (II) nitrate?
Nat2105 [25]

Answer:

The answer to your question is  Cu(NO₃)₂

Explanation:

To write the chemical formula of a molecule:

1.- Look for the symbols of the elements

Copper = Cu        has an oxidation number of +2.

Nitrate = NO₃⁻¹    nitrate is a polyatomic ion so it is composed of nitrogen,

                            oxygen and its oxidation number is -1.

2.- Write the chemical formula and interchange the oxidation numbers.

             Cu⁺² + NO₃⁻¹   ⇒   Cu(NO₃)₂

There are five constitutional isomers with the molecular formula C6H14. When treated with chlorine at 300°C, isomer A gives a mi
ozzi

Answer:

Pentane or 2,2-dimethylbutane  

Explanation:

I've numbered the isomeric hexanes from 1 to 5 and labelled the sets of equivalent hydrogens.

The results are

Isomer 1— three sets of equivalent hydrogens

Isomer 2— five sets of equivalent hydrogens

Isomer 3— four sets of equivalent hydrogens

Isomer 4— two sets of equivalent hydrogens

Isomer 5— three sets of equivalent hydrogens

Each set will give one monochloro substitution product.

4 = A. Two monochloro isomers.

2 = B. Five monochloro isomers.

3 = C. Four monochloro isomers.

Isomers 1 and 5 each give three monochloro isomers.

Thus, we cannot assign Structure D definitively.

D is either pentane or 2,2-dimethylbutane.
