Answer:
The correct answer is 17 meq/g
Explanation:
Ion exchange capacity (IEC) express the total of active sites of a resin in which ions are attached because the greater molecular weight.
The exchange Reaction can be represented as
R-H
The IEC value (in meq/g) is determinated by using the next equation:
IEC=[(mL of NaOH)*(M of NaOH)]/mass of resin
IEC [(17 mL)*(0.5 M)/0.5]= 17 meq/g
Answer:
It would increase the final quantity of products
Explanation:
According to the Le- Chatelier principle,
At equilibrium state when stress is applied to the system, the system will behave in such a way to nullify the stress.
The equilibrium can be disturb,
By changing the concentration
By changing the volume
By changing the pressure
By changing the temperature
Consider the following chemical reaction.
Chemical reaction:
2NO₂ ⇄ N₂O₄
In this reaction the equilibrium is disturb by increasing the concentration of reactant.
When the concentration of reactant is increased the system will proceed in forward direction in order to regain the equilibrium. Because when reactant concentration is high it means reaction is not on equilibrium state. As the concentration of NO₂ increased the reaction proceed in forward direction to regain the equilibrium state and more product is formed.
Answer:
Solubility
Explanation:
Solubility units that incorporate units of solution include grams of solute per 100 grams of solution or grams of solute per liter of solution. Another way to express solubility is in moles of solute per liter of solution; this ratio is called "molarity."
