Calcium reacts with hydrochloric acid, HCI, to make calcium chloride and hydrogen gas (H2). 1) write a word equation for this reaction.

2) write a balanced symbol equation for this reaction.

3) if 2g of calcium reacts completely with hydrochloric acid, what mass of calcium chloride is made?

The agent of mechanical weathering in which rock is worn away by the grinding action of other rock particles is call

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 is the volume occupied by 10.0 dm3 of gas at standard pressure after it has been compressedat constant temputure to 500.0 kpa?
