Neutralization Reaction Model
Neutralization reaction The reaction of an acid and a base to form water is called a neutralization reaction. When an acid and a base react, hydrogen ions from the acid (H+) and hydroxide ions from the … more
High School Chemistry
Ion Model (Whiteboard)
You can create ionic compounds by dragging and dropping atoms. Ion fragments that are no longer needed can be returned to their original location.
Making Molecular Models (Whiteboard)
You can create molecular structures by dragging the atoms. Atoms that no more needed can be returned to the periodic table.
Law of Definite Proportions
Law of Definite Proportions In a reaction where hydrogen gas is burned to produce water, two hydrogen atoms combine with one oxygen atom. Hydrogen gas and oxygen gas always react in a ratio of 2:1 to … more
Mendeleev’s Periodic Table
Arrange the element cards As Mendeleev did. You can move three or more consecutive cards as a group by dragging the middle. You can view it in full-screen mode by clicking the full-screen button. (There is … more
Equilibrium Constants
2●\(\rightleftharpoons\)● Chemical equilibrium In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations that have no further tendency to change with time. In an equilibrium state at … more
Root-Mean-Square Velocity of Gas Molecules (Vrms)
* The gas molecules in the above simulation are all of the same type, and the color of the molecules is for identification purposes only. Kinetic Molecular Theory of Gases ‘Kinetic Theory of Gases’ is a … more
Precipitation Reaction
A precipitation reaction is a type of reaction when two solutions react to form an insoluble solid (ionic salt) A lot of ionic compounds dissolve in water and exist as individual ions. But when two ions … more
