Answer: The atomic number
Answer:
b) low temperature and high pressure
Explanation:
Deviation of gases from their ideal behavior could be as a result of two things which include a very small volume for the gases and the collisions not being elastic enough.
Small volume will decrease the frequency of elastic collisions a gas will experience as a result of the tiny space.
Low temperature will decrease the amount of elastic collisions and energy of the gas and high pressure will decrease the volume which is why there will be a deviation in the ideal behavior of Hcl(g)
Answer:
Fossil fuels contribute to greenhouse gases, which is one of their major disadvantages. The most harmful for the environment is coal because it has many more harmful combustion products than other fossil fuels.
Answer: -
96 jet engines would be needed to make 24 model airplanes.
Explanation: -
We are told that
1 model airplane = 1 body + 2 wings + 4 jet engines + 1 tailpiece.
Thus,
24 model airplanes = 24 x (1 body + 2 wings + 4 jet engines + 1 tailpiece)
= 24 body + 48 wings + 96 jet engines + 24 tailpiece.
Thus we see that 96 jet engines would be needed to make 24 model airplanes.
