The original components retain their individual properties
Answer:- A) Exothermic, B) Reactant side(left side), C) Product side(right side), D) Reactant side(left side) and E) Le-chatelier's principle.
Explanations:- A)
of the reaction is negative and it indicates an exothermic reaction.
B) Equilibrium shifts to the reactant side if nitrogen gas is removed. If anything is added then reaction moves in a direction where this added component is used and if something is removed then reaction moves in a direction where this removed component is formed.
C) Exothermic reactions are favored at low temperature and endothermic reactions are favored at high temperature. The temperature is lowered, so the reaction will shift to the product side.
D) The reaction shifts to the reactant side if ammonia is added so that it could be used to reestablish the equilibrium.
E) Le-chatelier's principle helps to answer B-D. As per this principle, reaction shifts in a direction where the stress is relieved. It means if anything is added then it must be used and if something is removed then it must be formed.
Answer:
30.11 × 10²³ atoms
Explanation:
Given data:
Number of moles of gold = 5 mol
Number of atoms = ?
Solution:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance. The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ atoms
5 mol × 6.022 × 10²³ atoms /1 mol
30.11 × 10²³ atoms
Your answer is B. or 2 - After it has hit the ground.
