Answer:
I don't know because I don't know about chemistry
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 student measured the cup and got an incorrect answer
Explanation:
because he was in a rush.
Bitter taste (opposed to sour taste of acids)...
Slimy, or soapy feel on fingers (Slippery).....
Many bases react with acids and precipitate salts......
Strong bases may react violently with acids. An acid spill can be safely neutralised by using a mild base......
Bases turn red litmus paper blue.....
Bases are substances that contain metal oxides or hydroxides........
Bases which are soluble in water form alkalis (soluble bases)......
