Answer:
1.99V
Explanation:
Balanced redox reaction equation:
3CU2+(aq) + 2Al(s) ------> 3Cu(s) + 2Al3+(aq)
E°cell= E°cathode- E°anode
E°cell= 0.34-(-1.66)
E°cell= 2.0V
From Nernst equation:
E= E°cell - 0.0592/n logQ
E= 2.0 - 0.0592/6 log [3.43]/[1.63]
E= 2.0- 0.0032
E= 1.99V
Answer:
The answer to your question is: Carboxylic acid.
Explanation:
Carboxylic acid: Carboxylic acids are organic acids that have the carboxylic group.
Carboxylic group is a carbon attach with a double bond to oxygen (C = 0), with a single bond to a hydroxyl group (C - OH) and with a single bond to a chain of carbons.
The general structure is shown below.
Answer : The precipitate will not be formed when these solutions are mixed.
Explanation :
The chemical equation for the reaction of calcium chloride and lithium sulfate follows:
We are given:
Concentration of calcium ion =
Concentration of sulfate ion =
The salt produced is calcium sulfate.
The equation follows:
The expression of (ionic product) for above equation follows:
Putting values of the concentrations in above expression, we get:
There are 3 conditions:
- When ; the reaction is product favored. (No precipitation)
- When ; the reaction is reactant favored. (Precipitation)
- When ; the reaction is in equilibrium. (Sparingly soluble)
As, the . The above reaction is product favored. This means that no salt or precipitate will be formed.
Hence, the precipitate will not be formed when these solutions are mixed.
Answer:
Every mole contains 6.022 x 10^23 atoms regardless of what type of moelcules it is (Gold, Silver). So the anwer is 1.54 times 6.022 x 10^2
