c
Explanation:
when it become a solid the particals become more packed which becomes smaller
Answer:
1,42 Å
Explanation:
La longitud de enlace de Bi-I se obtiene por
Bi-I = Radio del átomo de Bi + Radio del átomo de yodo
pero radio del átomo de yodo = 1.39Å
Longitud del enlace Bi-I = 2,81 Å
Por lo tanto, el radio del átomo de Bi = 2,81 Å - 1,39 Å
radio del átomo de Bi = 1,42 Å
Answer:
The answer is : D. Wind energy
Answer:
K=1.93
Explanation:
Given reactions are:
A +2B ⇄ 2C K1=2.79
2C ⇄ D K2=0.186
D⇄ A+ 2B K=?
If we reverse the reaction then the euillibrium constant also become reciprocal of original value:
3rd reaction is a combination of reciprocal of 1st and 2nd reaction
2C⇄A +2B 1/K1;........................1
D ⇄ 2C 1/K2; ..............................2
On adding 1 and 2
D ⇄A +2B
K=1.93
