Explanation:
In a voltaic cell, oxidation reaction occurs at anode whereas reduction reaction occurs at the cathode.
Hence, the half-cell reaction taking place at anode and cathode will be as follows.
At anode (Oxidation) : ...... (1)
At cathode (Reduction) :
So, in order to balance the half cell reactions, we multiply reduction reaction by 3. Hence, reduction reaction equation will be as follows.
........ (2)
Therefore, overall reaction will be sum of equations as (1) + (2). Thus, net reaction equation is as follows.
Answer:
number of hydrogen atom in 1.8 mole of NH2OH =
Explanation:
percentage of hydrogen in NH2OH = mass of hydrogen / mass of whole molecule
=\times 100
= 9.09 percentage
therefore number of moles in 1.8 moles of hydroxy amine =
= .16 moles of hydrogen
number of hydrogen atom = (number of moles )×(avagadro number)
= atoms of hydrogen
Are there answer choices or is this a write in answer?
1 mol ------------ 6,02×10²³
0,17 mol ------- X
X =(0,17×6,02×10²³)/1
X = 1,0234×10²³ molecules H₂O
