Answer:
The answer is given below:
Explanation:
Strong acids have the ability to dissociate quickly as compared to the weak acids which dissociates slowly and can do that up to a certain level.
HCl is a strong acid and HA as stated in the statement is a weak acid.
So, in the beaker which contains HCl will have:
In the beaker with HA will have:
The reaction of Ca(oH)2 with HCl produces calcium chloride (CaCl2) and water (H2O). The stiochiometric equation is 2HCl + Ca(OH)2 = CaCl2 + 2H2O. In this case, 2 moles of HCl stoichiometrically reacts with one mole of calcium hydroxide. Hence for 3.5 moles of Ca(OH)2, there should be 1.75 moles of HCl needed. Given 0.85 M HCl, to get the volume, we divide 1.75 moles by 0.85 M. The volume needed is 2.0588 liters.
They have the same number of valence electrons.
No. You putting iodine solution is not for cleaning the onion but actually testing for starch. Onion is a plant that makes food. Thus, onion contains starch. If you put iodine solution onto starch-present organism. the brown solution will change to darkblue solution or blueblack solutiom due to the presence of starch. If there is no starch present, the solution will remain brown. Hence, the iodine solution is npt for cleaning but for testing for the presence of starch.
Answer:
2 C3H6 + 9 O2 6 H2O + 6 CO2
Theo. yield is 440.0 g CO2, % yield = 45.45% Explanation: hope it helps here for ur service
