Select the correct answer. a weather station predicts that warm, humid air will pass over much cooler land during the early morning hours. which precaution should the weather station give to residents who are driving to work that morning? a. bring extra water because the morning will be hot and dry. b. use headlights and drive slowly if you encounter dense fog. c. pack raincoats and umbrellas to prepare for severe rainstorms. d. plan for blizzard-like conditions by wearing snow boots and mittens.

it would be B because warm humid air+cool land=fog

B) Use headlights and drive slowly if you encounter dense fog.

Explanation: Fog begins to form when water vapor condenses into liquid water droplets that are suspended in the air. This happens when the air has a lot of moisture and when the temperature is low (because in this way the water in the air condenses). So if a weather station predicts that warm humid air will pass over much cooler land, the precaution must be to use healights and drive slowly because it will probably be dense fog.

calculate how many grams of ammonia can be produced from 4.21 grams of

n2 + 3h2 = 2nh3

my answer:

25.0g n2 x (1 mol/ 28.0gn2) x (2 mol nh3/ 1 mol n2) x (17.0g nh3/ 1 molnh3) = 30.36g n2

25.0g h2 x (1 mol h2/ 2.00g h2) x (2 mol nh3/ 3 mol h2) x (17.0g nh3/ 1 mol nh3) = 141.67g h2

lr = n2
