Which of the gases in the earth's atmosphere would you expect to find as molecules and which as individual atoms?
You would expect to find nitrogen and oxygen as molecules in the atmosphere, and argon as individual atoms.
Which chemical elements would you expect to find in abundance in a living cell?
carbon, oxygen, hydrogen
What is the electronegativity of the oxygen atom to that of the other molecules within the electron transport chain?
Oxygen has the second highest electronegativity of any element, second only to fluorine. Since it would be unusual to have fluorine in the electron transport chain, we can safely expect that oxygen will have the highest electronegativity in the chain.
Would BA and O form a polar covalent bond?
The electronegativity difference between Ba (EN 0.89) and oxygen (EN 3.44) is high and you would expect bonds to be ionic. Barium oxide is ionic.
Why did my friend die after putting on oxygen mask?
Your second question was: "can you overdose on oxygen wearing an oxygen mask?" The answer to that is no. Oxygen masks - as used by divers, fighter pilots and sometimes hospital patients - always offer a mix of oxygen and nitrogen so that oxygen poisoning cannot occur. However, if you were to put on a mask that makes you inhale only pure oxygen, it would after a little while start to poison your central nervous system. As to 'why your friend died': I have no idea.
Would you expect a fast moving mountain stream or the Mississippi River to have more dissolved oxygen?
I personally would expect the mountain stream to have more dissolved oxygen, because I know that oxygen dissolves better in cold water.
Can hospital ombudsman help settle hospital malpractice?
If you have a complaint or a problem with the hospital that would be the place to start, but don't expect any help with a lawsuit - REMEMBER - the hospital ombudsman is an EMPLOYEEE of the hospital.
Which of the gases in the earth's atmosphere would you expect to find as molecules and which as individual atoms?
You would expect to find nitrogen and oxygen as molecules in the atmosphere, and argon as individual atoms.
Would you expect it to be harder to remove an electron from Na or O?
oxygen
What would you do if you had a power cut if you had an oxygen concentrator?
You should have a standby cylinder of oxygen available just in case.
Would an oxygen cylinder be of use on the moon?
Only if you like breathing.
What results would you expect if two models were compared in a diffusion test?
The rate of diffusion would be faster for the right cylinder.
Which part of the periodic table would you expect to find oxygen?
Oxygen is in the upper right side of the periodic table.
What would you expect if two models were compared in a diffusion test?
The rate of diffusion would be faster for the right cylinder.
What results would you expect if these two models were compared in a diffusion?
The rate of diffusion would be faster for the right cylinder.
What result would you expect if these two models were compared in a diffusion test?
The rate of diffusion would be faster for the right cylinder.
Would you expect a plant to produce or oxygen on a sunny or a cloudy day?
On a sunny day because there is more sun to help produce oxygen
