Explanation:
Reduction is a chemical reaction in which electrons are gained by one of the atoms taking part in the reaction and lowering of an oxidation state of that atom.
Reduction takes place at the cathode.
In aqueous, vanadium(V) is present in +5 oxidation state which on reduction changes to vanadium(I) with +1 oxidation state.
The half reaction is :
A and C, Igneous and Metamorphic
The balanced equation for the above reaction is as follows;
3NO₂ + H₂O --> 2HNO₃ + NO
stoichiometry of NO₂ to NO is 3:1
molar volume is where 1 mol of any gas occupies a volume of 22.4 L
volume of gas is directly proportional to number of moles of gas.
therefore stoichiometry can be applied for volume as well.
volume ratio of NO₂ to NO is 3:1
volume of NO₂ reacted - 854 L
therefore volume of NO formed - 854 L /3 = 285 L
volume of NO formed - 285 L
Answer: 50 grams
Explanation: The water is still only going to be 50 grams. Although it’s in a different state, it didn’t gain or lose any water while being frozen.
Answer:
Cl2, Chlorine molecule has a boiling point closest to that of argon.
This is because Chlorine is made up of discrete and simple molecules making up a simple molecular structure. The molecules associate through weak van der waal's forces of attraction hence low boiling point.
HCl <em>has</em><em> </em><em>strong</em><em> </em><em>hydrogen</em><em> </em><em>bonds</em><em>.</em>
F2 <em>is</em><em> </em><em>very</em><em> </em><em>small</em><em> </em><em>hence</em><em> </em><em>strong</em><em> </em><em>forces</em><em> </em><em>of</em><em> </em><em>attraction</em><em>.</em>
HF <em>has</em><em> </em><em>strong</em><em> </em><em>hydr</em><em>ogen</em><em> bonds</em>
