Answer:

1.8 moles of O₂

Explanation:

The balance chemical equation for said double replacement (photosynthesis) reaction is as follow;

6 CO₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂

According to balance chemical equation,

6 moles of O₂ are produced by = 6 moles of CO₂

So,

1.8 moles of O₂ will be produced by = X moles of O₂

Solving for X,

X = 1.8 mol × 6 mol / 6 mol

X = 1.8 moles of O₂

Stoichiometric problems in which moles are given and moles or other reactant or product asked are the simplest problems. One should only write the balanced chemical equation and perform above method to find the required moles.

Answer:

butylphenyl ether.

Explanation:

The formula of the compound is:

CH₃ - CH₂ - CH₂ - CH₂ - O - C₆H₅

1. The functional group is of the kind R - O - R', i.e. two alkyl groups each attached to one end of the oxygen atom. That means that the compound is an ether.

2. One group attached to the oxygen group is CH₃ - CH₂ - CH₂ - CH₂ - which has 4 carbons and is named butyl group.

3. The other group attached to the oxygen atom is C₆H₅ - which is derived from ciclohexane as is known as phenyl group.

4. Using the rule of naming the subtituents in alphabetical order, you name butyl first and phenyl second, so it is butylphenyl ether.
