Answer:

The pressure exerted by the final gas is 18.1 kPa

Explanation:

We note that according to Dalton's law of partial pressure, the pressure a=exerted by a mixture of gases is equal to the sum of the partial pressures of the individual gases in the mixture

The gases and their partial pressures are;

Hydrogen = 40.8 kPa

Bromine = 26.7 kPa

Fluorine = 3.5 kPa

Helium = 12.7 kPa

Final gas pressure = required

Therefore,

40.8 + 26.7 + 3.5 + 12.7 + Final gas pressure = 101.8 kPa

83.7 kPa + Final gas pressure = 101.8 kPa

Final gas pressure = 101.8 kPa - 83.7 kPa = 18.1 kPa

The pressure exerted by the final gas = 18.1 kPa.

What are all the possible masses of cl2 molecules that are made when two chlorine atoms bond together?
Pavel [41]

The masses of the 2 most common isotopes of Cl are 35 and 37. Therefore we can formulate 3 possible masses of Cl2:

<span>
35 + 35 = 70 
35 + 37 = 72 
37 + 37 = 74 

<span>However, Cl 35 is the most common isotope of chlorine of the two therefore it is the most probable that two Cl 35 atoms will combine, so 70 is the most common among all.

1. Which of the following statements is a consequence of the equation E=MC2
finlep [7]

Answer:

D. All of the above​

Explanation:

E = MC² is a common equation in physics.

E is energy

M is mass

C is the speed of light

The law was stated by Albert Einstein.

  • From this law, it was shown that energy is released when matter is destroyed.
  • Mass and energy are equivalent as seen in nuclear reactions where mass is converted to energy.
  • Mass and energy is usually conserved in any process and this is a subtle modification of the law of conservation of matter and energy.
  • Most of these postulates apply to nuclear reactions which generally do not follow some precepts of chemical laws.
