Data In a methane molecule (C H 4 ), there are four single covalent bonds. In an octane molecule ( C 8 H 18 ), there are 25 single covalent bonds. How
does the number of bonds affect the dispersion forces in samples of methane and
octane? Which compound is a gas at room temperature? Which is a liquid?

the volume of fluid displaced would equal the volume of the gas. use a gas syringe - this is a laboratory instrument that can be used to withdraw a certain volume of gas from a closed system or to measure the volume of gas from a chemical reaction.

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
