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>

The speed of sound is given by the formula
Speed of sound = square root (Young's Modulus/density)
Young's modulus for gold = 78 GPa which is 7.8 * 10^10 Pa
Speed of sound = (7.8 * 10^10 / 19.3 ) = sqrt (4.04 * 10^9 )
Speed of sound = 6.36 * 10^4 m/s <<<=== answer.
It would be the skeletal system. This systems primary purpose it to give body its shape, support, protection, and makes new red blood cells from the bone marrow. Located deep inside bones.
