Suppose you had a piece of Silver metal sitting on the shelf, how many grams of tarnish will form (Ag2S) if the 3.87 g of silver exposed to air are completely reacted with the Sulfur contaminants that the air
contains?
Ag + S -> Ag2S

Which type of reaction always has an element and a compound as reactants

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).

What are transitions between a liquid and gas called? identify which way they are transitioning
