When particles are removed volume will do what

If I have 325 mL of oxygen gas at a temperature of 25°C, and I heat it to a temperature of 75°C, what is the new volume (in mL) ?

Why do weak acid-weak base reactions not go to completion? There are not enough molecules in solution to react with each other. The conjugate products are much weaker than the original acid and base.

What equation is the relationship between wavelength and frequency?

The molarity of an aqueous solution of hydroiodic acid, HI, is determined by titration with a 0.145 M potassium hydroxide, KOH, solution. If 45.7 mL of potassium hydroxide solution are required to neutralize 50.

Glucose is not made from which of the following

Rank the temperatures from the highest to the lowest. 133F 351K 25C 273K 146C 58F 95F

Calculate the density of sulfuric acid if 35.4 mL of the acid weighs 65.14 g.

Where the single machos?

A reaction will be spontaneous only at low temperatures if both ΔH and ΔS are negative. For a reaction in which ΔH = - 320.1 kJ/mol and ΔS = - 86.00 J/K · mol. Determine the temperature (in °C) below which the reaction is spontaneous.
