If 0.0714 moles of N2 gas occupies 1.25 L space, how many moles of N2 have a volume of 25.0 L? Assume temperature and pressure stayed constant.

How does the kinetic theory of gases explain the weather changes happening in the troposphere?

Nitric acid, a major industrial and laboratory acid, is produced commercially by the multi-step Ostwald process, which begins with the oxidation of ammonia: Step 1: NH3 (g) + O2 (g) LaTeX: / longrightarrow⟶ NO (g) + H2O (l) Step 2: NO (g) + O2 (g)

For clouds to form, water vapor in the air must condense and change from a gas to a liquid. What must water molecules do as part of this process?

How is condensation explained by the Kinetic Molecular Theory? Cooling reduces particle motion, resulting in coalescence by attractive forces. Cooling increases collisions, which causes molecules to bond together.

A rope experiences three 400 N forces to the left and three different 410 N forces to the right. (A) Will accelerate to the left (B) Will accelerate to the right (C) Will not accelerate

An ionic bond involves the transfer of what? * Olons Protons Electrons Neutrons
