Answer:
The s-, p-, and d-block elements of the periodic table are arranged into 18 numbered columns, or groups. The elements in each group have the same number of valence electrons. As a result, elements in the same group often display similar properties and reactivity.
Explanation:
The compound formed will be X2Y3 with oxidation number of X = +3 and of Y = -2.
Example of X2Y3 type compounds are Fe2O3 and Mn2O3.
Hope this helps!!
Answer:
I would say D (not sure tho)
Explanation:
Answer:
A). 2.1 × 
Explanation:
Given reaction,
2
(g) ⇄ 
(g) + 
(g)
The concentrations are as following;
= 5.82 × M
= 8.4 × 
M
= 8.4 × M
So,
= [( ) × ()] ÷ []^2
Now,
We can determine the value of by substituting the values in above formula:
= [ (8.4 × M) × (8.4 × M)] ÷ [(5.82 × )^2
= 2.08 *
= 2.1 ×
∵ = 2.1 ×
Thus, <u>option A</u> is the correct answer.
Answer:
The answer is false. See the explanation below, please
Explanation:
The equilibrium constant is the ratio of the concentrations of the products over the concentrations of the reactants.
See the example below:
A + B --> C + D
We calculate the Keq:
Keq = (C) x (D) / (A) x (B)
