Given the reaction equation; ClO3−(aq)+3Cu(s)+6H+(aq)→Cl−(aq)+3Cu2+(aq)+3H2O(l), the cell notation is Cu/Cu2+//ClO3-/Cl/Pt.
<h3>What is an electrochemical cell?</h3>
A electrochemical cell is one in which electrical energy is produced by chemical processess. In this case, the cell reaction equation is; ClO3−(aq)+3Cu(s)+6H+(aq)→Cl−(aq)+3Cu2+(aq)+3H2O(l).The electrode used here is Pt.
Looking at the equation, we can write the notation for the cell reaction as;Cu/Cu2+//ClO3-/Cl/Pt.

The proportion of field mice weighing more than 33 grams in the distribution will be about 0.2275
- Mean, μ = 25 grams
- Standard deviation, σ = 4 grams
- Score, X = 33 grams
We need to calculate the P(Z > Zscore)
Recall :
Zscore = (X - μ) ÷ σ
For X > 33 :
Zscore = (33 - 25) ÷ 4 = 2
Therefore, the probability would be expressed as :
P(Z > 2) = 1 - P(Z < 2)
From the normal distribution table :
P(Z < 2) = 0.97725
Therefore,
P(Z > 2) = 1 - 0.97725 = 0.02275

There are different kinds of functional group. The answer to the functional group, is below.
- (OH) Alcohol is one of the most polar and may act as a weak acid
- (COOH) Carboxylic acid serves as the acid.
- (C=O) Aldehyde: can be an isomer of a chemical ketone
- (S-H) Thiol usually transform to a disulfide bond
- (NH2) Amine serves to be the base of chemical compounds
- (PO4) Organic phosphate carries a negatively charged atom.
<h3>What is functional group ?</h3>
A functional group in organic chemistry is known to be a composition of atoms that is found inside a molecules that often bind together to react in certain ways.
The Examples of functional groups are the group hydroxyl, ketone, amine, and others.
