1. At atmospheric pressure, a sample of Cl2 gas has a volume of 3.45 L at 51.0ºC. What volume, in liters, will the Cl2 gas occupy if the temperature is decreased to -55.0ºC?

2. At constant temperature, a sample of 3.75 L of N2 at 775 mmHg pressure is compressed until the
volume decreases to 3.15 L. What is the new pressure of N2 in units of atmospheres?

What happens when an acid dissolves?

Many free radicals combine to form molecules that do not contain any unpaired electrons. the driving force for the radical–radical combination reaction is the formation of a new electron‑pair bond. consider the chemical equation. n(g)+no(g)⟶nno(g) n(g)+no(g)⟶nno(g) write lewis formulas for the reactant and product species in the chemical equation. include nonbonding electrons. n(g)n(g) select draw rings more erase select draw rings more erase select draw rings more erase n no(g)

The picture represents the process that produces most of the energy used by living organisms on earth. which process is represented in the picture? a) the magnetic attraction between two hydrogen nuclei. b) the fusion of hydrogen nuclei to produce a helium nucleus in the core of the sun. c) the fission of hydrogen nuclei to produce a helium nucleus in the core of the sun. d) the chemical reaction between hydrogen nuclei to produce a helium nucleus in earth's atmosphere.
