How can chemical equations be used to describe what happens in chemical reactions?
A chemical formula or molecular formula is a way of expressing information about the atoms that constitute a particular chemical compound.
The chemical formula identifies each constituent element by its chemical symbol and indicates the number of atoms of each element found in each discrete molecule of that compound. If a molecule contains more than one atom of a particular element, this quantity is indicated using a subscript after the chemical symbol (although 18th-century books often used superscripts) and also can be combined by more chemical elements. For example, methane, a small molecule consisting of one carbon atom and four hydrogen atoms, has the chemical formula CH4. The sugar molecule glucose has six carbon atoms, twelve hydrogen atoms and six oxygen atoms, so its chemical formula is C6H12O6.
Chemical formulas may be used in chemical equations to describe chemical reactions. For ionic compounds and other non-molecular substances an empirical formula may be used, in which the subscripts indicate the ratio of the elements.
The 19th-century Swedish chemist Jöns Jacob Berzelius worked out this system for writing chemical formulas.

What do Chemical equations show or describe?
Chemical equations show the reactants involved in a chemical reaction, the products formed, and the stoichiometry or proportions in which they react. They provide a concise way to represent what happens in a chemical reaction.
Why do scientists like to use chemical equations instead of word equations?
Chemical equations provide specific information about the reactants and products involved in a chemical reaction, including the ratio of the substances involved and the energy changes that occur. This level of detail is not conveyed in word equations, making chemical equations more precise and useful for scientific analysis. Additionally, chemical equations can be used to predict the outcome of reactions and to balance equations, which is important for accurate experimental design.
What happens when the first two chemical equations are added together?
When the first two chemical equations are added together, the reactants and products from both equations are combined to form a single overall chemical equation. This allows us to see how the different substances interact and transform in a chemical reaction.
Explain the difference between chemical properties and physical properties?
Chemical properties describe how a substance can form new substances by undergoing chemical reactions, like flammability or reactivity. Physical properties describe characteristics that can be observed without changing the substance's identity, like color, density, or melting point.
How does ammonia autoionization occur and what are its implications in chemical reactions?
Ammonia autoionization happens when ammonia molecules react with water molecules to form ammonium ions and hydroxide ions. This process can affect the pH of a solution and influence the outcome of chemical reactions involving ammonia.

What happens when a chemical reactions?
new products should be formed
Explain the difference between chemical properties and physical properties?
Chemical properties describe how a substance can form new substances by undergoing chemical reactions, like flammability or reactivity. Physical properties describe characteristics that can be observed without changing the substance's identity, like color, density, or melting point.
What happens to a liquid that forms during a chemical reaction?
This a normal product in many chemical reactions.
What happens with the sulfuric acid and is it a chemical change or physical change?
The chemical reactions of sulfuric acid are chemical changes.
What happens when the chemical reactions in our bodies do not function properly?
The result is an illness.
What chemical reactions happens within living things?
It is impossible to answer as there are at least 4,000.
What symbols are used to show what happens during a reaction?
Chemical equations are used to represent reactions; they consist of chemical formulas for the reactants and products, along with arrows indicating the direction of the reaction. Other symbols may include (+) to separate reactants or products, and coefficients to represent the amount of molecules involved.
