Her answers are very clear and easy to understand, she even take the effort to make a range of colours for the questions and answers which make it even neater and easy to read. But i think it would be better if she show the working of how she obtain the ionic equations. Great effort as well! She put in effort doing it too! Q1 Zinc nitrate reacts with aqueous ammonia (NH4OH) to form a salt and a base. I) Name the salt and the base.
