Octane rating. An octane rating, or octane number, is a standard measure of the performance of an engine or aviation gasoline. The higher the octane number, the more compression the fuel can withstand before detonating.

A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction.

coefficients are important to prove the law of conservation of mass. The coefficients in a balanced chemical equation indicate the relative number of moles of reactants and products. From this information, the components of reactants and products can be calculated.

Balanced chemical equations have the same number and type of each atom on both sides of the equation. The coefficients in a balanced equation must be the simplest whole number ratio.

So any time the number of gas molecules on the product side is the same as the number of gas molecules on the reactant side, Kc will be equal to Kp. What is the conversion factor for molarity to pressure for a gas, anyway? The answer comes simply from the ideal gas equation.

Keep in mind that because the units are in kJ/mol, we need to multiply by the stoichiometric coefficients in the balanced reaction equation. As we would expect, the standard enthalpy for this combustion reaction is strongly exothermic.

there is no way you can balance this.. mathematically its impossible to satisfy this by any whole number.. You wil realize it when you write set of linear equations for N,O,H species.. ... For whatever integer n you place on the left side, you need 2n NH3 and 2n HO.

To fully understand a chemical reaction, a balanced chemical equation must be written. Chemical reactions are balanced by adding coefficients so that the number of atoms of each element is the same on both sides. Stoichiometry describes the relationship between the amounts of reactants and products in a reaction.

How much of this, plus how much of that gives how much of something else? The balanced chemical equation tells us that two molecules of water in the liquid state react to form two molecules of H2 in the gas state and one molecule of O2 in the gas state.

We have a balanced chemical equation in which we now know the exact quantity of one of the reagents (KHP) – NaOH(aq) + KHC8H4O4(aq) = KNaC8H4O4(aq) + H2O(l) – thus we can determine the number of moles of NaOH that reacted with the KHP.
