Hello.
The answer is: D it produces hyrogen ions in a solution.
This is correct because when Arrhenius acid it turns into hydrogen ions.substance as an acid if it produces hydrogen ions H(+) or hydronium ions in water. A substance is classified as a base if it produces hydroxide ions OH(-) in water.
have a nice day
I cannot see your question to help you... sorry
are present in 
<u>Explanation:</u>
It is known that each mole of an element is composed of avagadro's number of molecules. So if we need to determine, we need to divide the number of molecules with the avagadro's number.
So,
As here 
molecules of carbon di oxide is given. So the moles in it will be
No. of moles of carbon dioxide = 
No. of moles = 
moles of carbon dioxide.
Thus,
of carbon dioxide are present in .
