There are many steps in designing such a footwear that is helpful in treating this problem. First of all they will look the other footwear available in the market and the problem that is not being solved by the available option.

They will do research and study a bit of orthopedics to get more knowledge about the bones and shoes.

Likurg_2 [28]

Answer:

Compound A: Benzoyl chloride

Compound B: Benzaldehyde - (tBuO)₃Al complex

Compound C: Benzaldehyde

Compound D: Benzyl alcohol

Explanation:

The lithium tri-tert-butoxyaluminum hydride that the first student used is a milder reagent than LAH and will stop reacting at the aldehyde.

The LAH that the second student used is much more reactive and will continue to reduce the benzoic acid as far as possible, going all the way to the alcohol.

See the attachment for the reaction steps.

A gas has a volume of 590 mL at a temperature of -55°C what volume will the gas occupy at 30°C
Ipatiy [6.2K]
Using ideal gas formula (PV=nRT), you can conclude that volume directly related to the temperature. That means an increase in temperature will cause an increased volume too. Note that the temperature is using Kelvin, not Celsius. The calculation would be:

V1/T1= V2/T2
590ml / (-<span>55+ 273)K = V2/ (30+273)K
V2= (590ml/ 218K) * 303K
V2= 820ml</span>
