Why do you need an automatic chemical equation?

In the middle and high school chemistry studies, chemical equation balancing It is the basis for all chemical calculations, chemical reaction characterization. Whether it is an oxidizing reaction or a complex organic burning, subsequent mass fraction calculations and Mole volume calculations will be abandoned once the grade factor is wrong.

Ours. Online chemical equationr Designed for students, teachers and chemical workers. It can process complex chemical reactions in a instant, and by means of matrix and count-out algorithms, it can precisely calculate the chemical measures of each reactor and the generator.

What's the principle of the equation?

The core principle of chemical levelling is Quality and law of continuity : The total number of atoms of elements before and after reaction remains unchanged. The bottom logic of this tool is as follows:

  • Parsing phase: The string entered by the user is to be deconstructed to the left (reactive) and right (generated). Extracts the elemental symbol of each molecule and its footer.
  • Statistical stage: Summarize all chemical elements involved in the reaction (e. g. C, H, O, Fe, etc.).
  • Algebra equation group construction: Gives an unknown coefficient to each molecular formula (e.g. a, b, c) and create equations for each element (e.g. sum of atoms of an element in the reaction = The sum of the atoms of the element in the generator.
  • Solver and Simplified: So solve these straight-lined sub-equipments and extract the minimum positive integer resolution, the final ration coefficient.

Four common methods of manual formulae for the equation.

Although automatic parity tools are available, mastery of manual parity is also key to the scores. Here are four main equations that are commonly used in chemistry:

  1. Minimal common multiple method: Search for elements that appear less frequently before and after reactions and are more variable in the number of atoms, with the minimum common multiple of their footer as a breakthrough. (applies to simple and combined reaction, decomposition response)
  2. Odd number of spouses: If the total number of atoms on one side of the equation is odd and even on the other side, multiply the corresponding material on the other side of the equation by 2 Make it even and then follow-up.
  3. Observation: For complex structures or atoms containing (e.g. sulphate root SO42 - sulfate root, nitrate root) The equation of NO3−) can be viewed as a whole if the atomic tropics have not been destroyed before and after the reaction.
  4. (b) Chemical price rise/down (e.g. loss of stability): This is the ultimate weapon of the high-school chemical flattening back reaction. The coefficients for oxidizers and reduction agents are determined by identifying elements that reflect a change in the compound price before and after the reaction, and by calculating the total price increase and the total price decrease to equalize them.

Attention to tool use

When entering the chemical formula, note that it is case sensitive (e.g. cobalt is Co, carbon monoxide is) CO）。 When you encounter a complex formula with brackets, the simplified version of this tool may require you to expand the brackets manually (e.g., by Cu(NO3)2 Writing CuN2O6 Get more accurate matches. For most common inorganic and organic reactions, the tool provides a second-scale response that is compatible with perfection.
