yes normal - my daughter started full body tantrums at 6months - arched back and kicking feet, etc.
At the younger age, you can simply not react (as long as they're not at risk of injuring themselves), wait it out and then comfort, etc.
I also have no problem telling a 10month old 'no no no' when they're doing something that they shouldn't do. They understand very well that young when they're doing something you like and don't like. They may not understand 'why', but they can get the jist of 'this gets this reaction'.
