The number you place to the left of a formula in a chemical equation is the coefficient, which represents the amount of that substance taking part in the reaction.
The stoichiometric coefficient represents the number of units of each substance taking part in a reaction. It indicates the ratios of reactants and products in a balanced chemical equation.
Yes, if adding one substance to another causes heat to be released or the temperature to increase, it is likely an exothermic reaction, which is a type of chemical reaction. The increase in temperature indicates that a chemical change is taking place as bonds are being broken and formed.
The number placed to the left of a formula in a chemical equation is the coefficient, which represents the stoichiometry or the ratio of moles of each substance involved in the reaction.
The stoichiometric coefficient is the number placed to the left of the formula for a substance taking part in a reaction to represent the amount of moles of that substance involved in the reaction. It helps balance the chemical equation by ensuring that the number of atoms of each element is the same on both sides of the equation.
The products of a chemical reaction are the substances that are formed as a result of the reaction taking place. These products can be different compounds or elements from the reactants that were present before the reaction occurred.

first when there's a physical change in the substance second there will be a solution or a formula to that substance third is, it involves temperature fourth is change in color of the substance fifth is the bubbling of another substance is yet an another clue that a chemical reaction has occured.
Because no chemical reaction is taking place. It is the same substance, just in a different state of matter.
Chemical ChangesAs opposed to a physical change, chemical changes are present when the substance undergoes a chemical reaction and produces a new substance. A chemical change is a chemical reaction that will always take place for there to be a chemical change. Signs that a reaction is taking place: Formation of gases (bubbles), Color change, production of heat or light, and the formation of a solid. a change in composition and characteristics of matter.new substance maybe formed.original substance and form may be lost.new color and shapeExamplesFermentationPhotosynthesisRusting nailSpoiling milkDigesting food

It indicates a chemical reaction because it changes from one substance to another.
A Catalyst enhances and speeds a chemical reaction without actually taking part in the reaction.
