When is the only time you don't use prefixes when naming covalent compounds? if it's a diatomic molecule like h2 if it's the first element in the compound and there is only one present if it's a diatomic molecule or if it's the first element in the compound and there is only one present you always use prefixes in all covalent compounds

Which actions would increase the rate at salt dissolves in water? stir the water? crush the salt? use less water? heat the water? cool the salt

Base your answer on the information below and on your knowledge of chemistry. nitrogen dioxide, no2, is a dark brown gas that is used to make nitric acid and to bleach flour. nitrogen dioxide has a boiling point of 294 k at 101.3 kpa. in a rigid cylinder with a movable piston, nitrogen dioxide can be in equilibrium with colorless dinitrogen tetroxide, n2o4. this equilibrium is represented by the equation below. 2no2(g) n2o4(g) + 58kj at standard pressure, compare the strength of intermolecular forces in no2(g) to the strength of intermolecular forces in n2(g).

How will the volume of a gas be affected if the pressure is tripled, but the temperature remains the same?
