Dear Priyanka

Thanks for asking us a question in Ask the Expert section of TopperLearning.com.

We cannot entertain more than 5 questions in a subject per day. In case of multiple questions within a query, please post each question individually and let us know where you are getting stuck so that we would be able to explain things better.
 
Solution for your first query:

In Daniel cell, the oxidation always takes place at anode. Hence, the electronget released at anode. Therefore, anode is negative. From anode, electrons goes to cathode through wire where reduction takes place. Therefore, cathode is positive.

 
Regards

Topperlearning Team.
