Well you want the answer with the same letter in it. A.k.a 2. This means they have the same element in them
O2 (Diatomic oxygen that we breathe) and O3 (Ozone that would be deadly to breathe) have different structures.
So the answer is 2
Answer:
A. Hydrogen cans oxygen are reactants
Explanation:
Oxygen has a charge of -2. Hydrogen has a charge of +1. So it takes two hydrogens to balange the one oxygen hence the H20. So the reaction is balanced, and H20 is indeed made up of 1 oxygen and 2 hydrogen atoms. The equation 2 hydrogen + 1 oxygen (<---reactants) = Water (<--product) So hence Hydrogen cans oxygen is not a true statement. If cans is a misspelling then C would be your answer.
Hope that helped
Answer:
<em>21.14 K</em>
Explanation:
<em>We know the Ideal Gas Equation is :-</em>
<em>PV = nRT</em>
<em>=> T = PV/nR</em>
<em>=> T = 6.5 x 20 / 7.5 x 0.082</em>
<em>=> T = 130 / 6.15</em>
<em>=> T = 21.14 K</em>
Answer:
(A) 
Solubility will increase.
(B) 
Solubility will decrease.
(C) 
Solubility will decrease.
Explanation:
a) According to Le Chatelier's Principle when a change is introduced in a reaction system at equilibrium, the system responds by the reaction shifting in the direction to counter the change introduced.
When the change introduced is addition of acid, some 
are consumed due to it and the system would respond by reaction shifting towards creation of more in the system by increased dissolution. Thus solubility increase.
(b) When are added, the reaction shifts to counter the change introduced of increased by shifting to side that decreases the increased . That happens by reaction shifting towards some 
precipitating back. Hence solubility decreases.
(c) The change introduced is addition of 
which will be countered by reaction shifting to side that decreases increased 
, which happens by some 
precipitating back. Hence solubility decreases.
