D. Matter is anything that is made of organic substances and is found on the earth.
Answer:
- Acetic acid (CH₃COOH) and hydronium ion (H₃O⁺)
Explanation:
Hello,
In this case, based on the acid-base theory which states that acids are known as H⁺ donors, if we consider the direct reaction:
It is clear that the acetic acid is the first H⁺ donor as it losses one H⁺ to turn into the acetate ion. Moreover, if we consider the inverse reaction:
It is also clear that the hydronium ion is the second H⁺ donor as it losses one H⁺ to turn into water.
Best regards.
Answer:
PCl₅ = 208.22g/mol. UF₆ = 352.03g/mol.
Explanation:
Find the atomic mass of each element–and if there's a subscript (you multiply the atomic mass by that much). P= 30.97g, Cl= 35.45g; 30.97+35.45(5) = 208.22g [same idea with UF₆]
Answer:
Chemical equilibrium will shift towards the left.
Explanation:
If we look at the equation AgCl(s) <---> Ag+(aq) + Cl– (aq)
We can see that the equation is balanced and the reaction has reached the state of chemical equilibrium where amount of reactants is same as the amount of products.
If we will add AgNO3 in this solution, that will disturb the chemical equilibrium of this reaction and cause the formation of more number of silver ions.
Then the system will try to counter the problem of excessive production of Ag+ ions and the production of silver ions will become less by the precipitation of great amount of AgCl (silver chloride). This is in accordance with Le Chatelier's principle, because Ag+ that is increasing due to addition of AgNo3 should decrease in order to maintain equilibrium.
Ag+(aq) + Cl– (aq) ---> AgCl(s)
When Ag becomes greater than Cl, this decreases the solubility of AgCl and it starts to precipitate out. This phenomenon is also commonly referred to be as common ion effect between AgNO3 and AgCl.
Hope it help!
