At constant pressure, increasing temperature causes gas volume to increase.

In a neutralization reaction, the products are always a salt and water.

In the reaction below, which species acts as the base? HCl(aq) + H₂O(l) → H₃O⁺(aq) + Cl⁻(aq)

In a Brønsted–Lowry acid–base reaction, acids donate protons and bases accept protons.

A reaction with a negative ΔH is exothermic.

Based on its Lewis structure and molecular geometry, BF₃ is best described as:

Which molecule is most likely to be a liquid at room temperature, and why?

At constant temperature, increasing pressure causes gas volume to decrease.  

A gas mixture has a total pressure of 1.20 atm. If nitrogen contributes 0.45 atm, what is the partial pressure of the remaining gas?

If a reaction absorbs heat, the surroundings experience a temperature decrease.
