A scientist measures the standard enthalpy change for this reaction to be -146.7 kJ/mol. NH NO3(aq)-N20(g) + 2 H2O(1) Based on this value and the standard formation enthalpies for the other substances, the standard formation enthalpy of N2O(g) is kJ/mol.​

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.

explanation:

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
