Chemistry help that shows its working.

Balancing equations, mole calculations and reaction mechanisms all come down to doing the steps in the right order. The tutor shows each step on the whiteboard, keeps track of every atom and unit, and explains why the method works.

I keep getting balancing equations wrong, can you show me one?
Let's balance the combustion of propane step by step on the whiteboard.
‹›Balancing a Combustion Equation
Copy

Unbalanced: C3H8+O2→CO2+H2OC_3H_8 + O_2 \rightarrow CO_2 + H_2O

Balance one element at a time

  • Carbon: 3 C on the left needs 3 CO2CO_2 on the right
  • Hydrogen: 8 H on the left needs 4 H2OH_2O on the right
  • Oxygen: count on the right first (6+4=106 + 4 = 10), then fix the left

Balanced equation

C3H8+5O2→3CO2+4H2OC_3H_8 + 5O_2 \rightarrow 3CO_2 + 4H_2O

Rule of thumb: balance carbon and hydrogen first, oxygen last. It's usually the one that needs a fraction before you clear it.

How the chemistry tutor helps

Atom counting made visible

A table of atoms on each side, updated as each coefficient changes.

Unit tracking

Grams to moles to particles, with units cancelling on the page so you can see it work.

3D molecules

The tutor can show molecules in 3D so shapes and bond angles make sense.

Chemistry topics it covers

  • Balancing equations
  • Moles and molar mass
  • Stoichiometry
  • Concentration and dilution
  • Atomic structure and bonding
  • Acids, bases and pH
  • Equilibrium
  • Organic reactions

Not on the list? Ask anyway: it covers any chemistry topic, and on Plus it answers from your own uploaded course notes.

How a session works

  1. 1.

    Ask out loud or type

    Press Start talking and talk like you would to a tutor, or type your question. You can interrupt it any time.

  2. 2.

    Watch it on the whiteboard

    The working appears one step at a time. Say "yes" to move on, or ask for a step to be explained another way.

  3. 3.

    Check you've got it

    It ends with a quick question to check, and remembers what you found hard for next time.

Questions about the AI chemistry tutor

Can I talk to it out loud?

Yes. Press Start talking and just talk, like a call with a tutor. You can interrupt it mid-sentence, and it puts the working on a whiteboard while it explains. Free accounts get 10 voice minutes a month, with no card needed.

Can it help with stoichiometry problems?

Yes. It sets up the mole ratio from the balanced equation and walks through each conversion with units.

Can it show molecules in 3D?

Yes, the whiteboard can show real molecule structures in 3D that you can rotate.
