Answer:
D. a relatively small fraction of the maximum number of possible hydronium ions.
Explanation:
A weak acid is an acid that is partially dissociated into its ions in an aqueous solution or water. A weak acid is one that does not dissociate completely in solution; this means that a weak acid does not donate all of its hydrogen ions (H+) in a solution
It is produced when an Arrhenius acid dissolves in water. So a weak acid would form a relatively small fraction of the maximum number of possible hydronium ions while in contrast a strong acid would form a relatively large fraction of the maximum number of possible hydronium ions.
The answer is (C) 2 hydrogen atoms
Answer:
=<em><u> 1.7 M</u></em>
Explanation:
Molecular mass of NaCl = ( 23+35.5 ) = 58.5g
58.5g of NaCl are weighed by 1 mole of NaCl
10.0g of NaCl will be weighed by ( 10÷58.5 )
<em> <u>= 0.17 moles of </u><u>NaCl</u></em>
100mL = ( 100÷1000)L = 0.1L
0.1L of a solution is occupied by 0.17 moles of NaCl
<u>1L</u> of solution will be occupied by [(1÷0.1)×0.17]
=<em><u>1</u></em><em><u>.</u></em><em><u>7</u></em><em><u> </u></em><em><u>M</u></em>
