Here’s the balanced equation for the reaction between nitrogen and hydrogen that produces ammonia (NH3): N2 + 3H2 → 2NH3 ΔH = -91.8 kJ

If the reaction consumes 21.7 grams of nitrogen, how much energy is absorbed or released by the reaction? Use the periodic table for the atomic weights of the elements.

Type the correct answer in the box. Express the answer to the correct number of significant figures.

71.1

Explanation:

Plato

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
