When both products are soluble, a double replacement equation will not produce a reaction.
<h3>What causes certain double displacement reactions to be inert?</h3>
We use the (s) symbol for solid because salt is an insoluble substance that will not dissolve in water. The silver, fluoride, potassium, and chloride ions would have effectively moved to a new location if there had been no precipitate formation, but they would still be floating around as ions. In this scenario no reaction happens.
<h3>What guidelines apply to responses involving double replacement?</h3>
A double replacement reaction occurs when two ionic compounds swap ions to form two new ionic compounds. The following response is an example of this kind: AB + CD AD + CB.

The pOH of a solution is related to the concentration of hydroxide ions in a solution. Also, it is related to the pH of the solution since the sum of pOH and pH is equal to 14. We can use this relation to solve this problem. We do as follows:
pH = -log[<span>1.7 × 10−9 M</span>] = 8.8
pOH + pH = 14
pOH + 8.8 = 14
pOH = 5.2
Answer:
The minimum amount of energy needed the the cell to perform various cellular,biochemical and physiological activities is known is Gibbs free energy.
Explanation:
The change in gibbs free energy of is very much important to determine whether a given reaction is spontaneous,non spontaneous or equilibrium.
1 If gibbs free energy change of a reaction is negative then the reaction is spontaneous.
2 If the free energy change is 0 then the reaction is in equilibrium stage.
3 If free energy change is positive then the reaction is non spontaneous.
The correct options are these:
1. It will follow the law of conservation of mass.
2.The mass of products will be equal to the mass of the reactants.
The law of conservation of mass states that ' matter can neither be created nor destroyed. Thus, if a chemical equation is balanced, the mass of the reactant at the beginning of the reaction will be equal to the mass of the product after the reaction. This shows that the chemical reaction obeys the law of conservation of mass.
