For learning about the half life of an element or substance, try half life calculator, So that you could practice on run time. Chemical equation product calculator works with same formula and procedure. Now we have a balanced chemical equation. So how can we get rid of this half molecule? The answer of this question is multiply both sides by two. We can also find the molecular weight online using molecular weight calculator. But we return with a problem because there is never half molecule noticed.īut we noticed here we have one and half a molecule of oxygen. Now we have the same exact number of iron and oxygen on the left-hand side as on the right-hand side. So the iron and oxygen combine together and then you get this annoying brown substance on your bike which is Fe 2O 3 and you know it as rust. Steel is 95% percent fine but the iron mixes with the rain which is just water and water contains oxygen. So this is a good example to show what happens when you leave your bicycle in the rain.īicycle is mostly made up of steel. If we mix iron (Fe) with two molecules of oxygen (O 2) together, you get compound (Fe 2O 3) and what is commonly known as rust. Or if you want to learn about the fraction of moles, we also have mole ratios calculator for your learning and practice. Those who are still struggling with this concept must use word equation to chemical equation converter and learn it completely.įor your learning regarding molecuels, use our grams to molecules calculator. It shows more information and allows us to see how many atoms and molecules are involved in each reaction.
CHEMICAL EQUATION BALANCER KHAN ACADEMY PLUS
The plus sign indicates that there is more than one reactant or product on each side of the equation.Ī word equation provides a good summary but a symbol equation provides more detail. The arrow -> is there to show that the reaction is irreversible. It remains the same while using balanced equation calculator. While writing chemical equation, the reactants are on the left before arrow and the products on the right.
