   What units are used to measure gaseous chemicals?

   • Therefore, the volumes of gaseous chemicals are primarily expressed in liters (L) and milliliters (mL). Temperature, T, is defined as the measure of how hot an object is. The U.S., metric, and SI units for measuring temperatures are degrees Fahrenheit (°F), degrees Celsius (°C), and Kelvin (K), respectively.

   What is the combined law of gas chemistry?

   • A closer look at the Combined Law reveals that the volume of a gas depends on both the pressure and temperature. Thus, if the volumes of two gases are to be compared, they must be under the same P and T. A commonly used set of P and T reference conditions is known as Standard Temperature and Pressure, or STP.

   How do you measure carbon dioxide in a gas syringe?

   • The volume of carbon dioxide gas produced can be measured using a gas syringe. Support a gas syringe with a stand, boss and clamp. Using a measuring cylinder, add 50 cm 3 of dilute hydrochloric acid to a conical flask. Add 0.4 g of calcium carbonate to the flask. Immediately connect the gas syringe and start a stop clock.

   How a hydrogen gas is measured using an eudiometer?

   • The hydrogen volume will be directly measured from the eudiometer scale. The hydrogen temperature will also be directly measured using a thermometer. However, the mole quantity and pressure of the hydrogen gas must be determined indirectly.

   What are the measurable properties of a gas?

   • On a microscopic level, the molecules (or atoms) in a gas are separated by large distances and are in constant, random motion. Four measurable properties can be used to describe a gas quantitatively: pressure (P), volume (V), temperature (T) and mole quantity (n).
