Give the products of the reaction of butanal, with: (a) sodium borohydride, in methanol (b) hydrogen cyanide, with catalytic cya
miss Akunina [59]

Answer:

Answers are given below

Explanation:

(a) Aldehyde groups are reduced by sodium borohydride in methanol to give alcohol.

So, butanal produces butanol on reaction with sodium borohydride in methanol.

(b) Aldehyde forms cyanohydrin when they are treated with HCN with catalytic cyanide.

(c) Aldehydes are oxidized by potassium dichromate in dil. sulphuric acid to produce carboxylic acid.

(d) Aldehyde produces acetal with methanol and a trace amount of acid catalyst.

(e) Aldehyde gives condensation reaction with CH_{3}CH_{2}NH_{2} to produce imine.

Structures of products for the given reaction has been shown below.

Determine the total pressure of a mixture of 0.400 mole of He and 0.600 mole of Ne in a 2.00 liter container at 25oC.
harina [27]

Answer:

Total pressure of the mixture is 12.2 atm

Explanation:

Let's apply the Ideal Gases law to solve this

Total pressure . V = Total moles . R . T

Total moles = 0.4 m of He and 0.6 mole of Ne → 1 mol

P . 2L = 1 mol . 0.082 L.atm/mol. K . 298K

P = ( 1 mol . 0.082 L.atm/mol. K . 298K) /2L

P = 12.2 atm

A certain solution is 70% ethanol and the rest being distilled water. If there are 12 moles of ethanol per litre of solution, fi
Aleks04 [339]

Answer:

0.55284g/mL

Explanation:

Hello there!

In this case, given the by-mass percent of ethanol:

\frac{70gEt}{100gSol}

It is possible to compute the density by using its molar mass to find the grams in one liter of solution:

12\frac{molEt}{1L}*\frac{46.07 gEt}{1molEt}=552.85g/L

However, by taking the g/mL we obtain:

552.84\frac{g}{L} *\frac{1L}{1000mL}=0.55284g/mL

Which is the density of the solution.

Best regards!
