4. A gas occupies 1.56 L at 2.00 atm. What will be the volume of this gas if the pressure becomes 4.00 atm?
tekilochka [14]

Answer:

<u>0.78 L</u>

Explanation:

From Boyle's Law :

P₁V₁ = P₂V₂

Here :

  • P₁ = 2.00 atm
  • V₁ = 1.56 L
  • P₂ = 4.00 L

Solving :

  • V₂ = P₁V₁ / P₂
  • V₂ = 2 x 1.56 / 4
  • V₂ = 1.56 / 2
  • V₂ = <u>0.78 L</u>

Write a short note on a simple microscope​
Annette [7]

Answer:

A simple microscope is one that uses a single lens for magnification, such as a magnifying glass while a compound microscope uses several lenses to enhance the magnification of an object. It uses a lens to enlarge an object through angular magnification alone, giving the viewer an erect enlarged virtual image.

Which combination of reagents used in the indicated order with benzene will give m-nitropropylbenzene? a. 1) CH3CH2CH2Cl/AlCl3,
VladimirAG [237]

Answer:

1) HNO3/H2SO4, 2) CH3CH2CH2Cl/AlCl3

Explanation:

Benzene is a stable aromatic compound hence it undergoes substitution rather than addition reaction.

When benzene undergoes substitution reaction, the substituent introduced into the ring determines the position of the incoming electrophile.

If I want to synthesize m-nitropropylbenzene, I will first carry out the nitration of benzene using HNO3/H2SO4 since the -nitro group is a meta director. This is now followed by Friedel Craft's alkykation using CH3CH2CH2Cl/AlCl3.
