Moles of CO₂ produced will be 4.5

<u>Explanation:</u>

CH₄ + 2O₂ → CO₂ + 2H₂O

Molecular weight of CH₄, M = 16

given mass of CH₄, m = 72

moles of CH₄, n = given mass / molecular mass

n = \frac{m}{M} \\\\n = \frac{72}{16} \\\\n = 4.5

Therefore, number of moles of CH₄ present is 4.5

According to the balanced equation,

1 mole of CH₄ produces 1 mole of CO₂

4.5 moles of CH₄ will produce 4.5 moles of CO₂

Therefore, moles of CO₂ produced will be 4.5

Arte-miy333 [17]

We have that the the liquid is

  • C_2H_5OH (ethanol
  • And at a condition of H_2SO4 as catalyst and temp 170

From the question we are told

  • A student wished to prepare <em>ethylene </em>gas by <em>dehydration </em>of ethanol at 140oC using sulfuric acid as the <em>dehydrating </em>agent.
  • A low-boiling liquid was obtained instead of ethylene.
  • What was the liquid, and how might the reaction conditions be changed to give ethylene

<h3>Ethylene formation</h3>

Generally the equation is

2C_2H_5OH------CH3CH_2O-CH_2CH_3+H_20

Therefore

with ethanol at 140oC

The product is diethyl ethen

The reaction at 170 ethylene will give

C_2H_5OH-------CH_2=CH_2+H_2O( at a condition of H_2SO4 as catalyst and temp 170)

Therefore

The the liquid is

  • C_2H_5OH (ethanol

and this is the second one,

the tilt of the Earth on its axis

Seasons change because of the tilt of the Earth and the planet's movement around the Sun. Did you know? It takes about 365.25 days for the Earth to orbit the Sun. We have leap years to make up for the extra ¼ day!
