Answer:
Species present in the solution after complete reaction: 
Explanation:
First balance the chemical equation,

calculation of mili moles of each:

mili mole of AgNO3= 15mili mole;
mili mole of K2CrO4=10 mili mole;
From balance equation,
2 mili mole of AgNO3 reacts with 1 mili mole of K2CrO4
hence 1 mili mole of AgNO3 reacts with 0.5 mili mole of K2CrO4
15 mili mole of AgNO3 reacts with 7.5 mili mole of K2CrO4
so only 7.5 milimole will be used in the reaction and 2.5 mili mole left in solution.
species present in the solution after complete reaction:

are soluble in water so it will dissociate in the solution
Answer:
I believe the answer your looking for is out of A or B
Explanation:
Option B because if the heat increases its essentially causing the concentration to increase by replacing the weak bonds with stronger ones
C) can give up electrons more readily than others.
Hydrogen has the lowest density.
Explanation:
The electrons in the outermost electron shell are responsible for forming chemical bonds. These electrons are also known as valence electrons
