Answer:    

The prefix di means 2 and the prefix hexa means 6.

As per IUPAC rules you must use the prefixes to indicate the number of atoms of each element in the formula.

So, the proper name for the compound C2H6 is dicarbon hexahydride.

Why do airbags fill evenly with gases?
Firdavs [7]

Answer:

The signal from the deceleration sensor ignites the gas-generator mixture by an electrical impulse, creating the high-temperature condition necessary for NaN3 to decompose. The nitrogen gas that is generated then fills the airbag.

basically, the nitrogen fills the bag

Five gases combined in a gas cylinder have the following partial pressures: 3. 00 atm (N2), 1. 80 atm (O2), 0. 29 atm (Ar), 0. 1
Helen [10]

The total pressure of the gaseous mixture has been 5.37 atm. Thus, option D is correct.

The partial pressure has been defined as the pressure exerted by each gas in the mixture.

According to the Dalton's law of partial pressure, the total pressure of gas has been the sum of the partial pressure of the gases in the mixture.

The given partial pressure of gases in the mixture has been:

  • Partial pressure of Nitrogen, P_N_2=3\;\rm atm
  • Partial pressure of Oxygen, P_O_2=1.80\;\rm atm
  • Partial pressure of Argon, P_A_r=0.29\;\rm atm
  • Partial pressure of Helium, P_H_e=0.18\;\rm atm
  • Partial pressure of Hydrogen, P_H=0.10\;\rm atm

The total pressure of the gaseous mixture has been:

P=P_N_2\;+\;P_O_2\;+\;P_A_R\;+\;P_H_e\;+\;P_H\\P=3\;+\;1.80\;+\;0.29\;+\;0.18\;+\;0.10\;\text {atm}\\P=5.37\;\rm atm

The total pressure of the gaseous mixture has been 5.37 atm. Thus, option D is correct.
