In a laboratory activity, a student measures the pH values of four household liquids and distilled water, as shown in the table below. During this laboratory activity, appropriate safety equipment is

In the United States, nearly all fuel for automobiles is a mixture of gasoline and ethanol, C2H5OH. The equation below represents a reaction between ethene and water to produce ethanol.

As plants grow, light energy is converted into chemical energy during the process of photosynthesis. The reaction produces glucose and oxygen. The balanced equation below represents photosynthesis.

The Ostwald process is an industrial method to produce nitric acid, HNO3(aq), used in the manufacture of fertilizers. Several steps are involved in this process. In the first step, ammonia and oxygen

Several elements are considered endangered because there is a risk of these elements becoming unavailable for commercial uses in the next 100 years. Helium, zinc, gallium, indium, and tellurium are in

During a laboratory activity, 15.0 mL of hydrochloric acid, HCl(aq), is exactly neutralized by 18.2 mL of 0.11 M sodium hydroxide, NaOH(aq). During the laboratory activity, appropriate safety equipmen

When solid copper is placed in an aqueous silver nitrate solution, a reaction occurs, as represented by the equation below.

Nitrogen dioxide gas, NO2(g), can reach equilibrium with dinitrogen tetroxide gas, N2O4(g), in a closed system. At 1.0 atmosphere, the boiling point of N2O4 is 21°C. The equation below represents this

Consider the equilibrium N2O4(g) <---> 2NO2 (g) ΔH = 58.0kJ In which direction will the equilibrium shift when a. N2O4 is added
