Answer:
b) Industrial farming
Explanation:
The term “industrial agriculture” refers to the type of farming which raises and cultivates large numbers of livestock and plants in high-density environments. It uses modern technology to promote faster growth and reduce illness and death rates in livestock, creating food products on a mass scale.
Answer:
The number of moles of water will be produced when 8.0 moles of ethane are burned = 24.0 mol.
Explanation:
- It is a stichiometry problem.
- The balanced equation of burning ethane is:
2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O
- It is clear that 2.0 moles of ethane (C₂H₆) burns in 7.0 moles of oxygen and produce 4.0 moles of CO₂ and 6.0 moles of H₂O.
<em><u>Using cross multiplication:</u></em>
2.0 moles of ethane produces → 6.0 moles of H₂O, from the stichiometry.
8.0 moles of ethane produces → ??? moles of H₂O.
- ∴ The number of moles of water will be produced when 8.0 moles of ethane are burned = (6.0 x 8.0) / (2.0) = 24.0 mol.
Answer:
T = 3.75 K
Explanation:
As we know
PV = nRT
R =8.3144598 J. mol-1. K-1
P = 0.562 atm
V = 83.3 mL
moles in 0.392 g of I2 = 0.392/mass of I2 = 0.392 grams/253.8089 g/mol = 0.0015 moles
Substituting the given values, we get
0.562 atm * 83.3 *10^-3 L = 0.0015 moles * 8.3144598 J. mol-1. K-1 * T
T = 3.75 K
Answer:
Radon or Oganesson
Explanation:
Hello,
Considering that the higher both the critical temperature and pressure the higher both the attractive and repulsive intermolecular forces, there will be a larger deviation from ideality for the elements nearer to the 6th or 7th period in group VIIIA (noble gases). Furthermore, their atomic radius is bigger, which increases the probabilities of molecular collisions, circumstance that is neglected in the ideal gas law.
Best regards!
