The work As a Chemistry AI Training Reviewer, you will help improve how AI handles chemistry questions. You will work with text responses and judge whether answers are accurate, clear, relevant, and faithful to the prompt. You will assess both the final answer and the reasoning behind it, then explain what is correct or needs improvement. Your feedback will help improve model accuracy, fluency, and contextual relevance.

• Review AI-generated chemistry answers for accuracy, clarity, and adherence to the prompt.
• Find errors in calculations, methods, chemical facts, and conceptual understanding.
• Write clear chemical explanations and strong model solutions.
• Rate and compare multiple AI responses for correctness and reasoning quality.
• Fact-check chemical information and evaluate step-by-step problem solving.
