What types of reactions cannot involve a free element as a reactant?
Combustion reactions cannot involve a free element as a reactant since they involve the reaction of a fuel-rich substance with an oxidizing agent to produce heat and usually carbon dioxide and water. Two nonmetals combining to form a covalent bond also cannot involve a free element as a reactant.
Why is a catalyst not a product or reactant of a chemical reaction?
If a substance is a reactant or product of a chemical reaction then, by definition, it cannot be a catalyst.
Why is a catalyst not a product or a reactant of a chemical reaction?
If a substance is a reactant or product of a chemical reaction then, by definition, it cannot be a catalyst.
Is sodium chloride a reactant or product?
It can be either, depending on the reaction. Sodium chloride is a product of the reaction of sodium hydroxide and hydrochloric acid. Sodium chloride is a reactant in the ion exchange reaction in a water softener to remove calcium from hard water.
Why does an unbalanced equation not describe a reaction fully?
An unbalanced equation does not describe a reaction fully because the number of atoms of each element on the reactant side must equal the number of atoms of that element on the product side. Balancing the equation is important to ensure that the law of conservation of mass is obeyed, meaning atoms cannot be created or destroyed during a chemical reaction.
Why a catalyst is not considered a reactant or product in a chemical reaction?
If a substance is a reactant or product of a chemical reaction then, by definition, it cannot be a catalyst.
Why are chemical equations always balanced?
Chemical equations are always balanced to satisfy the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. Balancing equations ensures that the number of atoms of each element on the reactant side is equal to the number of atoms of the same element on the product side.
Why is iron is a limiting reactant?
It is unique from reaction to reaction. If it is the more basic question that I think it might be, you always look at the moles of each reactant and what ratio they react. If they react 1:1, then the reactant with less moles will be consumed first, and therefore quenches that particular reaction naturally
What would happen to the amount of products if you increase the amount of one of the reactants?
Increasing the amount of one reactant typically increases the amount of products produced until the reactant is used up. Once the reactant is exhausted, the reaction will reach equilibrium and the amount of products will no longer increase.
Can an element be broken with chemical reaction?
Base elements cannot be broken using a chemical reaction. Mollecules, which are made up of more than one element, can be broken using chemical reactions.
Can a catalyst change the orientation of a reactant collision?
No, a catalyst cannot change the orientation of a reactant collision. Catalysts work by providing an alternate reaction pathway with lower activation energy, but they do not influence the orientation of reactant collisions. The orientation of reactant collisions is determined by the relative positions and orientations of the reacting molecules.
If a substance cannot be broken down by heat the substance is an element?
No. Elements cannot be broken down into simpler substances in a chemical reaction.
