Physical States

The physical state of a substance indicates its form at a given temperature and pressure, typically categorized as solid (s), liquid (l), gas (g), or aqueous (aq). In the reaction, sodium is a solid (s), water is a liquid (l), hydrogen is a gas (g), and sodium hydroxide is in an aqueous solution (aq).

Chemical Equation

A chemical equation is a symbolic representation of a chemical reaction, showing the reactants on the left and the products on the right, separated by an arrow. It conveys the conservation of mass, indicating that the number of atoms of each element is the same before and after the reaction, which is essential for balancing the equation.

교과서 질문

High temperature combustion processes, such as in combustion engines and coal-fired power plants, can result in the reaction of nitrogen and sulfur with oxygen to form nitrogen oxides (NO𝓍) and sulfur oxides (SO𝓍), where x can vary. These NO𝓍 and SO𝓍 compounds subsequently undergo further reaction in the atmosphere to create acidic compounds that contribute to acid rain.

a. Do some research to determine the common products that are formed (i.e., what are the values of x) for the reactions of N and S with oxygen. Write balanced equations for these reactions.
