Ammonia reacts with oxygen according to the equation 4n h 3 (g)+5 o 2 (g)→4no(g)+6 h 2 o(g),δ h rxn =−906 kj calculate the heat (in kj ) associated with the complete reaction of 155 g of n h 3 .

-2.07 × 10³ kJ

Explanation:

Let's consider the following balanced equation.

4 NH₃(g) + 5O₂(g) → 4 NO(g) + 6H₂O(g)    ΔHrxn =−906 kJ

The enthalpy of reaction is -906 kJ, that is, 906 kJ are released upon the reaction of 4 moles of NH₃. Taking into account that the molar mass of NH₃ is 17.0 g/mol, the heat associated with the complete reaction of 155 g of NH₃ is:

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.

they all get energy from eating other animals, dead animals to be more precise.

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.
