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:
Li is more reactive then Be.
Explanation:
As you go to the farther left and down on the periodic table, the higher that element reactivity is.
Explanation:
The given data is as follows.
Cross-section area of the rectangular is as follows.
Area = 
= 
= 
Tension applied on the specimen is 35,500 N
Now, formula to calculate the modulus of elasticity for a material of aluminium is as follows.
E = 70 GPa
= 
or, = 
Now, stress on the specimen is as follows.

= 
= 
According to Hook's law, we will calculate the resulting stain as follows.


= 
=
Thus, we can conclude that the resulting strain is
.
