4. For the following word equation, write a balanced equation and identify the type of reaction that is occurring:
When aqueous magnesium chloride combines with aqueous copper (II) nitrate, aqueous
magnesium nitrate and copper(II) chloride crystals are formed.

As air becomes more dense, (select all that apply) o. air weighs less o. gas molecules are closer together o. air is colder o. air weighs more o. gas molecules are further apart o. air is hotter

Nitrogen dioxide decomposes according to the reaction 2 no2(g) ⇌ 2 no(g) + o2(g) where kp = 4.48 × 10−13 at a certain temperature. if 0.70 atm of no2 is added to a container and allowed to come to equilibrium, what are the equilibrium partial pressures of no(g) and o2(g)

What are the other two pieces of glassware you used in this experiment that you could obtain hundredths digit accuracy?
