Using the notation just described, represent a cell based on the following reaction: clo3−(aq)+3cu(s)+6h+(aq)→cl−(aq)+3cu2+(aq)+
Veseljchak [2.6K]

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.

a researcher is studying a group of field mice. the distribution of the weight of field mice is approximately normal with mean 2
yarga [219]

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
