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: 2-Methylpentane
Explanation: The numbering is not brought to a minimum.
The moon affects the tide. the sun affect the weather like polar attraction
Physical change because water is not a gas or change . you can see through it.
Answer:
Molarity = 0.13M
Explanation:
n=m/M = 4.87/74.55= 0.065mol, V= 500ml= 0.5dm3
Applying
n= C×V
0.065= C×0.5
C= 0.13M
