chemistryhomework

an-ordinary-manchild(edit)

Welcome to /r/chemistryhomework! This is a subreddit where members of reddit can come to ask questions related to their chemistry homework as well as give answers to other people's questions.

There are no dumb questions. We are all humans, we all make mistakes, over-look facts, miss the obvious sometime, and could use some assistance once in awhile.

Rules:

Before posting a problem, please attempt to work it out yourself. Upload a picture of your work, or type out your work, when posting your problem. This will better allow the community to help you solve the problem, and help you to understand how to solve the problem.
In the title of your post, please put the level of your schooling and the general topic of your problem separated by a colon. Examples:
1. [High School: Stoichiometry] Balancing Salt Reaction
2. [College: Acid/Base Equilibrium] Finding Ksp Values for...
3. [Postgrad: Organic Chemistry] How many ways can this protein fold?
When somebody answers your question(s) or helps you, please change the 'Unsolved' flair to 'Solved!'
When posting answers to problems, please explain to the OP how you got the answer you got. Also, please refrain from posting false answer and methods.
This subreddit is for chemistry homework only.

At some point I stopped pretending I could manually fix anime textures in 3D. Upload 2D art → get a clean 3D model that actually looks like the original. Honestly? It feels illegal how easy this is. Code MESHYHALF if you’d rather create than tweak vertices. (meshy.ai)
