Chemical Formulas

Equation Maker supports chemical formula notation using specialized commands. These commands automatically format chemical formulas with proper subscripts, superscripts, and spacing.

Command Description
\ce{formula} Chemical equation/formula (primary command)
\cf{formula} Chemical formula (alias for \ce)
\cee{formula} Chemical equation (alias for \ce)

Chemical Formula Syntax

Inside \ce{}, \cf{}, or \cee{}, you can write chemical formulas naturally:

  • Element symbols are automatically formatted: \ce{H2O} → H₂O
  • Subscripts are created from numbers: \ce{H2SO4} → H₂SO₄
  • Superscripts use ^: \ce{Ca^2+} → Ca²⁺
  • Charges: \ce{SO4^2-} → SO₄²⁻
  • Reaction arrows: \ce{A -> B} for forward reaction
  • Reversible reactions: \ce{A <=> B} for equilibrium
  • Coefficients: \ce{2H2 + O2 -> 2H2O}
  • State symbols: \ce{NaCl(aq)}, \ce{H2O(l)}, \ce{CO2(g)}, \ce{ite(s)}

Chemical Formula Examples

Simple Compounds

\ce{H2O}
\ce{NaCl}
\ce{H2SO4}
\ce{Ca(OH)2}

Ions and Charges

\ce{Na+}
\ce{Cl-}
\ce{Ca^2+}
\ce{SO4^2-}
\ce{Fe^3+}

Chemical Reactions

\ce{2H2 + O2 -> 2H2O}
\ce{NaOH + HCl -> NaCl + H2O}
\ce{CH4 + 2O2 -> CO2 + 2H2O}

Common Number Sets

Use \mathbb{} for blackboard bold number sets:

Command Symbol Description
\mathbb{N} Natural numbers
\mathbb{Z} Integers
\mathbb{Q} Rational numbers
\mathbb{R} Real numbers
\mathbb{C} Complex numbers

Example Equations

Here are some complete example equations you can use as templates:

Quadratic Formula

x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}

Pythagorean Theorem

a^2 + b^2 = c^2

Euler's Identity

e^{i\pi} + 1 = 0

Definition of Derivative

f'(x) = \lim_{h \to 0} \frac{f(x+h) - f(x)}{h}

Definite Integral

\int_{a}^{b} f(x) \, dx = F(b) - F(a)

Summation Example

\sum_{i=1}^{n} i = \frac{n(n+1)}{2}

Matrix Multiplication

\begin{pmatrix} a & b \\ c & d \end{pmatrix} \begin{pmatrix} x \\ y \end{pmatrix} = \begin{pmatrix} ax + by \\ cx + dy \end{pmatrix}

Binomial Coefficient

\binom{n}{k} = \frac{n!}{k!(n-k)!}

Gaussian Integral

\int_{-\infty}^{\infty} e^{-x^2} \, dx = \sqrt{\pi}

Taylor Series

e^x = \sum_{n=0}^{\infty} \frac{x^n}{n!}

Multi-line Aligned Equations

 
(a + b)^2 &= (a + b)(a + b) \\
&= a^2 + ab + ba + b^2 \\
&= a^2 + 2ab + b^2
 

Piecewise Function

f(x) = \begin{cases}
x^2 & \text{if } x \geq 0 \\
-x^2 & \text{if } x < 0
\end{cases}
