What is the final temperature when 20.0 g of water at 25°C is mixed with 30.0 g of water at 80°C?

Strong conductivity of plasma allows it to act and react as and

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 do you identify the anode on a power source such as a battery? how do you identify the cathode? how are terms anion and cation?
