Give the major product formed when phenol is heated with concentrated H2SO4 and SO3. (There is more than one correct answer, but
iris [78.8K]

Answer:

See image attached and explanation

Explanation:

The reaction of phenol with SO3/H2SO4 is an electrophilic reaction. The electrophile attacks portions of high electron density in the substrate phenol.

The -OH group activates phenol towards electrophilic substitution at the ortho and para positions, hence the product(s) formed in this reaction(only one product is shown here as required by the question).

The sulphonation of phenol using concentrated sulfuric acid at lower temperature yields majorly the ortho product whereas at higher temperature the para product predominates.

the molecular weight of the nitrous oxide is 44.013 g/mol. assuming standard temperature and pressure, what would be the volume,
allsm [11]

The volume of the nitrous oxide gas is 1729.3 Liters

<h3>What is the number of moles of gas present in 3.40 kg of nitrous oxide?</h3>

The number of moles of gas present in 3.40 kg of nitrous oxide is determined from the formula below:

Numbers of moles = mass/molar mass

the mass of nitrous oxide = 3.40 kg or 3400 g

the molar mass of nitrous oxide = 44.013 g/mol

Moles of gas = 3400 / 44.013

Moles of gas = 77.25 moles

Using the ideal gas equation to determine the volume of the gas:

PV= nRT

V = nRT/P

where;

  • V is the volume of gas
  • n is the number of moles of gas
  • R is molar Gas constant = 0.082 L.atm/mol/K
  • T is the temperature of the gas

V = 77.25 * 0.082 * 273 / 1

The volume of the gas = 1729.3 Liters

What causes a pendulum to move in an extended amount of time?
yawa3891 [41]
Longer pendulums swing with a lower fequency than shorter pendulums. The force of gravity accelerates the pendulum down. The momentum built up by the acceleration of gravity causes the mass to swing in the opposite direction to a height equal to the original position. So therefore I think the answer your looking for is gravity.
