What information In a balanced chemical equation shows how many moles of a reactant are involved in the reactant?
The 'BIG' number to the left of a chemical substance is the 'molar ratio'. e.g. 2NaOH(aq) + H2SO4(aq) = Na2SO4(aq) + 2H2O(l) In words ' Two moles of sodium hydroxide react with one mole of sulphuric acid, to produce one mole of sodium sulphate and two moles of water. NB The number '1' is never shown as a molar ratio. When no number is shown, read it as '1'(one).
How are a reactant and a product alike?
A reactant exists at the beginning of a chemical reaction whilst a product exists at the end. They are alike in the fact that to get to a product you need to have a ready supply of the reactants. An example of a simple reactant/product reaction is shown below. Magnesium + Oxygen --> Magnesium Oxide Reactant + Reactant --> Products Hope this helps
What does a chemical reaction show?
It shows the preservation of mass and of matter.
What evidence of a chemical reaction is shown in the photo?
lol what photo
What kind of chemical relation is shown 2H2 plus O2 equals 2H2O?
A balanced chemical reaction.
Which of the molecules in this chemical equation shown is a reactant?
Reactants are the substances that participate in a chemical reaction to form products. In a chemical equation, the molecules or compounds written on the left side are the reactants.
What is the chemical equation shown is a reactant?
Reactants are to the left in a chemical equation.
How is the law of conservation of mass shown by a balanced chemical eqaution?
The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. In a balanced chemical equation, the total mass of the reactants is equal to the total mass of the products, illustrating the conservation of mass. Each element on the reactant side must be accounted for on the product side, ensuring mass balance.
Which of the molecules in this chemical equation shown is a reactanct?
The molecules on the left side of the arrow in a chemical equation are the reactants. They are the starting substances that undergo chemical reactions to form products.

How is an endothermic reaction indicated in an equation apex?
An endothermic reaction in an equation is typically indicated by the presence of heat as a reactant. For example, in a chemical equation, if heat is shown as a reactant (usually on the left side of the arrow), it suggests that the reaction requires energy input to proceed, making it an endothermic reaction.
Which molecules is produced during the process shown of chemical process?
The term "chemical process" refers to the method of altering, or treating one or more chemicals to produce something else. The type of molecules which may be produced during this process is wholly reliant on the chemical which is being used.
The number that tells how many molecules of a particular substance take part in a chemical reaction is?
In a balanced equation for the reaction, the coefficient appearing immediately before the formula for a reactant describes the number of moles of that reactant involved in the reaction shown by the equation.
How is endothermic reaction identified in an equation?
heat is included as a reactant in the reaction - apex
Why is the light energy written on the left of the equation?
because of glucose
What is carbon dioxide molecule?
carbon dioxide has two types of molecules Carbon (C) and Oxygen (O).It has one carbon and two oxygens which is shown in its chemical foormula C02
