Is a home microwave suitable for organic synthesis ?

Chemistry

1 answer:

o-na [289]4 years ago

7 0

Explanation:

The specially designed microwave units , for the synthesis , are often very expensive and at times get heated up .

The home microwave is suitable only in some case .

And , new modification done on the home microwave , increases the safety factor .

The chemical reactions which need to be done at very high pressure , are preferred to be carried in specially designed oven .

Hence ,

the home microwave is suitable only for some selected and specific reactions .

What is the IUPAC name for the compound shown?

Anna [14]

Answer:

2,2,3-trimethyl-pentane

Explanation:

The longest chain is 5 carbons so the parent chain is a pentane. There are two methyl groups coming off the second carbon in the chain and 1 methyl group coming off the 3rd carbon in the chain. In total there are 3 methyl groups, hence we get 2,2,3-trimethyl-pentane.

From the mass of Al reacted, how many moles are present? What is the mole ratio between Al and H2 in the balanced chemical react

tigry1 [53]

Answer:

From the mass of Al reacted, how many moles are present? We don't have the mass of Al reacted

What is the mole ratio between Al and H2 in the balanced chemical reaction?

By stoichiometry, ratio between Al and H₂ is 3:2

What units are required on the temperature when doing calculations with gases? °K degrees

The value of R is 0.082 L.atm/mol.K

Explanation:

A chemical reaction for this can be this one:

2Al (s) + 6HCl (aq) → 2AlCl₃(aq) + 3H₂ (g)

Balanced

To get the moles which are present in the mass of Al reacted you must calculate:

Al Mass / Al molar mass = Al moles

The Ideal Gas equation is this one:

Pressure . Volume = n° moles . R (gases constant) . T°K

The temperature must be in K, because the units of R

We usually use R = 0.082 L.atm/mol.K

Question 107 points)

____ [38]

Answer:

Evaporation from the hydrosphere provides the medium for cloud and rain formation in the atmosphere. The atmosphere brings back rainwater to the hydrosphere. The atmosphere provides the geosphere with heat and energy needed for rock breakdown and erosion. The geosphere, in turn, reflects the sun's energy back into the atmosphere.
