Chemistry Task 1: Fill in the missing labels for the equipment in the chemistry experiment below.​

What pressure will be exerted by 0.675 moles of a gas at 25*c if it is in a 0.750-l container?

Consider the following reactions. (note: (s) = solid, (l) = liquid, and (g) = gas.) mg(s) + ½o2(g) → mgo(s) + 146 kcal/mole h2(g) + ½o2(g) → h2o(g), δh = -57.82 kcal/mole what type of reaction is represented by the previous two examples?

Which change to the system wood cause the freely-moving piston to lower?
