The enthalpy of reaction for the given above and any other given can be calculated through the equation,
Hrxn = H(product) - H(reactants)
From reliable sources, the values of H of the substances.
H(NO) = 90.25 kJ/mol
H(O2) = 0 kJ/mol
H(NO2) = 33.18 kJ/mol
Substituting the known values,
Hrxn = (2)(33.18 kJ/mol) - (2)(90.25 kJ/mol)
Simplifying,
Hrxn = -114.14 kJ
<em>ANSWER: -114.14 kJ</em>
Answer:
The first one is air the second is decreases the third is water the fourth is gas and the last is liquid.
Explanation:
Hope it helps.
Hm, this could be more than one option, but gaining electrons makes a negative charge, so
If atoms of a halogen nonmetal (Group 17) gains one electron, the atoms the have "a negative one charge".
Because magnesium loses its electrons easily than aluminum
Answer:
A sound wave is the pattern of disturbance caused by the movement of energy traveling through a medium (such as air, water, or any other liquid or solid matter) as it propagates away from the source of the sound. The source is some object that causes a vibration, such as a ringing telephone, or a person's vocal chords.
