Answer:
Xenon hexafluoride's molar mass is about 245.28 g/mol
Formula mass is about 245.28 u.
Explanation:
So we want to find the formula mass of the XeF6 and there is a special formula for that.
You have to multiply the number of each element in XeF6 by the element's atomic mass.
The atomic mass of Xe is 131.293, and F's atomic mass is multiplied by 6, due to the 6 at the bottom. F's atomic mass is 18.998403, so we multiply the atomic number by 6, which would equal 113.990418. Round if you want, but it would equal mostly the same thing. Add it up to get ≈245.28, which is the same thing.
Therefore the formula mass of XeF6 is 245.28 u.

Answer: B, E and F.
Explanation:
Just took a test on it and those were the correct answers.
Answer:
An atom becomes anion when it gains or loses electrons. The ions that are formed when an atom loses electrons are positively charged because they have more protons in the nucleus than electrons in the electron cloud.

Answer:
There are two possible answers to the question
I) decreasing the pressure of the system
II) decreasing the temperature of the system
Explanation:
Looking at the equation of the reaction, it can be seen that the reaction is endothermic. This implies that decreasing the temperature favours the reverse reaction and more NO2 is produced.
Secondly, decreasing the pressure drives the equilibrium position towards the side having the higher total volume hence decreasing the pressure favours the reverse reaction and more NO2 is produced.
