Hey I hve problems with calculate stoichiometry problems and next week I have a test about it can someone help me out and give me a site where everything is written step by step ....thank u guys :) I REALLY NEED HELP NO JOKING
I must have posted this to you last night 10 times. It is a step by step example of a stoichiometry problem (KClO3 and oxygen) and it shows you step by step what to do. If you don't understand something about it, post with a copy of what you've done and explain the trouble you are having.

Of course, I'm here to help! Stoichiometry problems can be challenging, but with proper understanding and practice, you'll be able to ace your test. Instead of providing you with just one website, I'll give you a few excellent resources where you can learn stoichiometry step by step:
1. Khan Academy (www.khanacademy.org): Khan Academy provides comprehensive video tutorials and practice exercises on stoichiometry. The step-by-step approach helps you understand the concepts and solve problems.
2. ChemCollective (chemcollective.org): ChemCollective offers interactive online modules and virtual labs to help you grasp stoichiometry. It includes step-by-step instructions and practice problems with detailed explanations.
3. Brightstorm (www.brightstorm.com): Brightstorm provides video lessons on various chemistry topics, including stoichiometry. Their concise and easy-to-understand explanations aim to help you master the subject.
4. ChemTeam (www.chemteam.info): The ChemTeam website hosts a wide range of tutorials that break down stoichiometry concepts and calculations. It includes detailed explanations along with practice problems and solutions.
Remember, practice is key when it comes to mastering stoichiometry. Work through as many problems as possible, and if you get stuck, try to identify the specific step or concept that is causing difficulty. By utilizing these resources and actively practicing, you'll build confidence and be better prepared for your test. Good luck!
