When the pressure of a gas doubt, does the volume: A. Doubles B. triples C. Halves D. Quarters E. Remains constant

What is the relationship between the volume of water and the dripping time?

A solution has a concentration of 0.6mol/dm³. If a container of this solution holds 3 moles of solute, what volume of solution is in the container?

The mole and Avogadro's number are now almost synonymous with each other. We say that one mole of a substance is the amount that contains Avogadro's number of particles. However, both concepts were developed independently at different times.

Glucose is not made from which of the following

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.
