Calculate the mass of water in a bank of fog hovering over Beaverton on a moderately foggy day. Assume that the surface area of Beaverton is 53 km² and the fog reaches to an altitude of 100 m. On a moderately foggy day, the density of water vapor in air will be 5 x 10⁻⁸ g/cm³. A) 3 x 10³ g
B) 2 x 10⁴ g
C) 3 x 10⁸ g
D) 2 x 10⁹ g
E) 3 x 10⁶ g

Heat is the total potential energy of a substance that can be transferred. true false

To prevent the presence of air, noble gases are placed over highly reactive chemicals to act as inert "blanketing" gases. a chemical engineer places a mixture of noble gases consisting of 4.37 g of he, 13.36 g of ne, and 36.65 g of kr in a piston-cylinder assembly at stp. calculate the partial pressure in torr of kr.

In what way do investigations build scientific knowledge? the results of investigations lead to questions that cannot be tested. they reflect the opinions and social values of scientists, ensuring valid information. the results of investigations lead to new questions, which lead to new investigations. they are not influenced by the research of earlier scientists, so they are able to address gaps in understanding.i
