Homework can be frustrating, especially when you don't understand what you're doing. Sometimes you do understand it but that doesn't get it done faster. Dealing with out of school studies on chemical reactions is just like dealing with any other kind of homework. If you need clarification on the different types, just read below.
When you're doing your work, you have to recognize the chemical reactions and identify which ones pertain to your questions. Keep the different types nearby so that if you need to double-check the type to make sure you're thinking of the correct one, you have it handy. It's likely that you will need to go back and forth between the two: homework questions and different types of chemical reactions.
Dealing with your homework can be difficult, but you don't have to do it alone. You can find help in many forms. If you go online, there are some websites that can help with your problems. You can find examples that might be useful to you, and advice on something you didn't think of. There are even some chat rooms dedicated to homework help. If those don't work out for you, Youtube can be surprisingly useful with homework help.
Sometimes the internet isn't much help though, so the next option is to ask a parent or guardian for help. Even if they can't help you, they might know someone who can.
Whenever there is a subject you might have difficulty with, it's important to have a “study buddy”. If you don't understand something, your buddy might be able to help you. If your buddy doesn't understand something, you might be able to help them. Also, you can divide and conquer, working on your questions together rather than being stuck on your own.
