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.
Which of what? I don’t see a picture.
The Bronsted base in H2S +H2O → H3O^+ + HS^- is H2O
Explanation
According to Bronsted Lowry definition of an base , that is a base is a compound that act as a protons acceptor. These protons are in form of hydrogen ions . H2O in the above equation accept one hydrogen ions to form H3O^+
Answer:
Will group 2 elements lose electrons to bond with nonmetals in group 17 in a
1:2 ratio?
Explanation:
Metals are electropositive in nature. This means that they loose electrons. Thus, metals form ionic bonds by loosing electrons to non metals.
Elements of group 2 have a valency of 2 while those of group 17 has a valency of 1 so the ratio in which group 2 elements bond with elements of group 17 is 1:2. Hence the answer.
Answer:
:)
Explanation:
Petroleum gas is mainly C3 and C4 based (propane and butane), whilst natural gas is predominantly C1 and C2 (methane and ethane). Petroleum gas is generally produced via the cracking of naphtha, which is one of the components separated during crude oil refining.
