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).

Answer:
31
Explanation:
In order for an atom to have a neutral charge, it needs to have the same number of protons and electrons. You can see by the illustration that the atomic number is 31, so this element has 31 protons. Knowing that, we also know that it must have 31 electrons to be neutral.
Answer:
valence electrons are the electrons that are located in the outermost electron shell of an element. Knowing how to find the number of valence electrons in a particular atom is an important skill for chemists because this information determines the kinds of chemical bonds that it can form and, therefore, the element's reactivity
Explanation:
Answer: Vander waals
Explanation:
Tellurium is a chemical element with atomic number 52. It's symbol is Te.
Nitrogen is a chemical element with atomic number 14. Its symbol is N
VANDER WAALS bond is found between Nitrogen and Tellurium, just as in Tellurium(II) Nitrogen.
This bond is relatively weak compared to some other kinds of bonds.
That is why tellurium and most of its compounds are usually brittle and easily grounded.
So, Vander Waals bonds is the answer
