Consider the total ionic equation below.
2NHI+20H + 2H++502- → 2NH4+2H2O+502-
What are the spectator ions in this equation?
OH and OH
O H+ and NHH
O NHI and 50%-
o so and OH

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
