- The state symbols in brackets show the physical state of. the substance at the reaction temperature. Solid (s), liquid (l), gas (g), or dissolved in water (aq). aq is called aqueous which comes. from the Latin word aqua meaning water. If you do not know the state of a substance. see melting and boiling points. If the melting point is above the reaction temperature, the substance is solid (s). If the boiling point is below the reaction temperature, the substance is gas (g).

Chemical reaction Chemical equations are used to graphically illustrate chemical reactions. They consist of chemical or structural formulas of the reactants on the left and those of the products on the right. They are separated by an arrow (→) which indicates the direction and type of the reaction; the arrow is read as the word yields.n a synthesis reaction, two or more simple substances combine to form a more complex substance. These reactions are in the general form: Two or more reactants yielding one product is another way to identify a synthesis reaction.

- A chemical equation expresses the net change in composition associated with a chemical reaction by showing the number of moles of reactants and products. But because each component has its own molar mass, equations also implicitly define the way in which the masses of products and reactants are related.

General Chemistry/Print version Return to Stoichiometry Menu. The Meaning of the Word. The word stoichiometry derives from two Greek words: stoicheion (meaning element) and metron (meaning measure). Stoichiometry deals with calculations about the masses (sometimes volumes) of reactants and products involved in a chemical reaction. It is a very mathematical part of chemistry, so be prepared for lots of calculator use.

Reactions in Water or Aqueous Solution Several types of reactions occur in water. When water is the solvent for a reaction, the reaction is said to occur in aqueous solution, which is denoted by the abbreviation (aq) following the name of a chemical species in a reaction. Three important types of reactions in water are precipitation, acid-base, and oxidation-reduction reactions.

Chemical Reactions Describing interactions among chemical species, chemical reactions involve a rearrangement of the atoms in reactants to form products with new structures in such a way as to conserve atoms. Chemical equations are notations that are used to concisely summarize and convey information regarding chemical reactions.

Stoichiometry and Balancing Reactions Stoichiometric Coefficients. In a balanced reaction, both sides of the equation have the same number of elements. The stoichiometric coefficient is the number written in front of atoms, ion and molecules in a chemical reaction to balance the number of each element on both the reactant and product sides of the equation. Though the stoichiometric coefficients can be fractions, whole numbers are frequently used and often preferred.

Information conveyed by a chemical equation A chemical equation conveys both qualitative and quantitative informations. Qualitatively, a chemical equation tells the names of the various reactants and the products. Quantitatively- a chemical equation represents: 1  The relative number of reactant and product species taking part in the reaction. 2  The relative number of moles of the reactants and products. 3  The relative masses of the reactants and products. 4  The relative volumes of gaseous reactants and products.

Reactions A chemical equation is a way to describe what goes on in a chemical reaction, the actual change in a material. Chemical equations are written with the symbols of materials to include elements, ionic or covalent compounds, aqueous solutions, ions, or particles.There is an arrow pointing to the right that indicates the action of the reaction.he materials to the right of the arrow are the products, or materials that have been produced by the reaction. The Law of Conservation of Mass states that in a chemical reaction no mass is lost or gained. The Law of Conservation of Mass applies to individual types of atom.

Why Must Chemical Equations Be Balanced? In balanced equations, only whole numbers are used as coefficients. The coefficient or subscript is not written out if they equal 1. Balanced chemical equations also include the state of matter that the reactants and products are found in. These can include gaseous, solid, liquid or aqueous. Aqueous compounds are usually ionic compounds.

How to tell if compound (or element) is (aq), (l), (g), (s)? Best Answer: aq is aqueous, or dissolved in water. l is liquid. g is gas. s is solid. If it is below its melting point, then it is solid. If it is above its boiling point, then it is a gas. In between is a liquid and dissolved in water is aqueous. The following reaction occurs in water at room temperature: AgNO3(aq) + KCl(aq) → AgCl(s) + KNO3(aq) The reactants are soluble in water and are aqueous.

How to Calculate Q of Reaction In chemistry, Q is the reaction quotient. It is used to determine which direction a reaction will proceed by comparing it to the equilibrium constant, Kc. At equilibrium, the forward reaction and the reverse reaction rates are equivalent. If Kc is greater than Q, then the reaction proceeds in the forward direction (to the right), creating more products.

3.3 Chemical Equations In a balanced chemical equation, both the numbers of each type of atom and the total charge are the same on both sides. Equation 3.9 and Equation 3.10 are balanced chemical equations. What is different on each side of the equation is how the atoms are arranged to make molecules or ions. A chemical reaction represents a change in the distribution of atoms but not in the number of atoms.
