Question

what are the conditions should be maintained to obtain hydrogen and oxygen from water​

Answer 1

Explanation:

When you start a sentence with an introductory phrase or clause beginning with “except,” you almost certainly force the reader to reread your sentence. You are stating an exception to a rule before you have stated the underlying rule. The audience must absorb the exception, then the rule, and then usually has to go back to grasp the relationship between the two. Material is much easier to follow if you start with the main idea and then cover exceptions and conditions.
