<h3><u>Answer;</u></h3>
Oxidation number of O =-2 and N= +2
<h3><u>Explanation;</u></h3>
- The oxidation number of an atom is the charge that atom would have if the compound was composed of ions.
- NO is a gas whose oxidation number is zero.
- The oxidation number of oxygen is almost always -2
- Therefore to find the oxidation number of Nitrogen;
<em>-2 + x = 0</em>
<em>x = +2 </em>
<em>The oxidation number of N is + while that of O is -2 </em>
Answer:
Option D, 116 g of NaNO3
Explanation:
An unsaturated solution is the one in which the amount of salt dissolved in more than the maximum amount of salt that can be dissolved in it.
At 50 degree Celsius, 37 grams of salt can be dissolved in 100 ml of water. Hence, 116 gram of salt is the correct answer
2NH3 + 3CuO———- 3Cu + 3H2O + N2
False
As Nuclear Reactor is not not a good idea to do so.
We should be able to trasfer the heat energy to produce steam and the run turbine.
Also electricity is transferred to our homes through various appliances and fuses.
