The answer is gas and it involves the Kinetic molecular theory which is a model used to predict gas behavior. Molecules or atoms
Answer:The world population increased from 1 billion in 1800 to 7.7 billion today. The world population growth rate declined from 2.2% per year 50 years ago to 1.05% per year. Other relevant research: World population growth – This article is focusing on the history of population growth up to the present.
Explanation:
Answer:
9
Explanation:
let f(x)= x-7 be equation i
let g(x)= x^2 be equation ii
Substitute x-7 as x in equation 2
implies gf(x) = (x-7)^2=(x-7)(x-7)
substitute x=4 implies
gf(x) = (4-7)(4-7)=(-3)(-3)=9
Equilibrium constant for the reaction CaCl₂.2H₂O (s) <-------> CaCl₂ (s) + H₂O (g) is [H₂O]².
Equilibrium constant is a temperature dependent constant which does not depend on the concentration of reactant or product.
The reaction given is:
CaCl₂.2H₂O (s) <-------> CaCl₂ (s) + H₂O (g)
The equilibrium constant for the given reaction is given by:
Keq = [H₂O]² [CaCl₂] / [CaCl₂.2H₂O]
Since, we know that the concentration of a solid remain unity.
Hence, [CaCl₂] = 1
[CaCl₂.2H₂O] = 1
So, the equilibrium constant becomes,
Keq = [H₂O]²
Hence, Equilibrium constant for the reaction CaCl₂.2H₂O (s) <-------> CaCl₂ (s) + H₂O (g) is [H₂O]²
