Based on the enthalpy of the reaction, 41625 kJ of heat is needed to produce 1850 grams of ammonia (NH3).
<h3>What is heat of reaction?</h3>
The heat of reaction or enthalpy change is the heat absorbed or evolved when reactant molecules react to form products.
According the enthalpy value of the reaction, 4 moles of ammonia require 1530 kJ of heat for its formation.
Molar mass of ammonia = 17 g
Mass of 4 moles of ammonia = 4 × 17 = 68 g
1850 g of ammonia will require = 1850 × 1530/68 = 41625 kJ of heat.
Therefore, 41625 kJ of heat is needed to produce 1850 grams of ammonia (NH3).

Yes. It is element No. 8 on the periodic table.
Answer: 
, 
Explanation:
Temperature of the gas is defined as the degree of hotness or coldness of a body. It is expressed in units like 
and 
These units of temperature are inter convertible.
We are given:
Temperature of the gas = 
Converting this unit of temperature into by using conversion factor:
Converting this unit of temperature into by using conversion factor:
Thus the temperature on the Celsius and Kelvin scales are and respectively.
