Answer:
None
Step-by-step explanation:
A high pH is caused by an excess of hydrogen ions over hydroxide ions.
Hydrogen ions are so small that they pass through the pores of an ordinary filter.
Thus, ordinary filtration has no effect on the pH of water.
4FeS2 + 11O2-> 2Fe2O3 + 8SO2
Not sure.... I think this is it

Answer: Adding a reactant will shift the reaction towards the products.
Adding a product will shift the reaction towards the reactants.
Removing a reactant will shift the reaction towards the reactants.
Removing a product will shift the reaction towards the products.
Explanation:
Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.
Adding a reactant will increase the concentration of reactants and hence the reaction will try to undo the increase by shifting the reaction towards the products.
Adding a product will increase the concentration of products and hence the reaction will try to undo the increase by shifting the reaction towards the reactants.
Removing a reactant will decrease the concentration of reactants and hence the reaction will try to undo the decrease by shifting the reaction towards the reactants.
Removing a product will decrease the concentration of products and hence the reaction will try to undo the decrease by shifting the reaction towards the products.
For hydrogen-like atom electron transition from n=3 to n=5, it would be classified as an absorption of energy. For hydrogen-like atom electron transition from <span>n=3 to n=2, it would be classified as an emission of energy. Hope this helps. Have a nice day.</span>
