Max number of columns

Hello

I have a form to be filled by users that has 100 questions where every question will be mapped to a column.

What would be the max number of columns allowed in a table? Also will the number of key-value pair that will be passed through Android/IOS to the server pose a problem in the request?

Thank you

Also will the number of key-value pair that will be passed through Android/IOS to the server pose a problem in the request?
