Answer:
0.322630 mols
Explanation:
You have to divide the given by the molar mass then multiply by the mol ratio which in this case is 1:1
Answer:
N2+O2-> 2NO
Explanation:
An endothermic reaction refers to a reaction in which heat taken in. This implies that heat is usually absorbed by the reaction system. The enthalpy of reaction for an endothermic reaction is always positive.
The triple bond between two Nitrogen atoms in N2 gas is very strong due to its small size and the triple bond thus the nitrogen molecule has a high dissociation energy. This accounts for the large amount of energy required to break the triple bond between nitrogen atoms in the nitrogen molecule. This causes the oxidation of Nitrogen molecule to NO to be largely endothermic.
2 Na + 2 H2O --> 2 NaOH + H2
Answer: The order of increasing energy is: radio < infrared < red < blue < UV < x rays
Explanation:
Electromagnetic wave is defined as the wave which is associated with both electrical and magnetic component associated with them.
The electromagnetic radiations consist of gamma rays , X rays , Ultraviolet , Visible , Infra red , microwaves and radio waves arranged in order of decreasing frequency and increasing wavelengths. The visible region consists of violet , indigo , blue , green , yellow, orange and red lights in order of decreasing frequency or increasing wavelength
The relationship between energy and frequency of the wave follows the equation:
where,
= frequency of the wave
E = energy of wave
From the above relation, it is visible that energy and frequency follow direct relation. For increase in value of frequency, energy increases and vice-versa.
Thus the order of increasing energy is: radio < infrared < red < blue < UV < x rays
