What is the mass of snow (in tons) on a 150.0ft by 45.0 ft flat roof after a 6.0 inch snowfall? Assume that 11 inches of snow is
Aneli [31]
6 inches of snowfall would be equivalent to 6/11 inches of water or 6/132 feet. So the volume of the equivalent amount of water on the roof is 150 ft. x 45 ft. x 6/132ft. = 306.8 cubic feet.   
Since there are 907185 grams in a ton and 28316.8 mL in a cubic foot, 1.00 g/mL is equivalent to 0.0312 tons/cubic foot  
Multiplying the two results gives 9.58 tons of snow.

Which set contains non-equivalent members?A) enthalpy and heat contentB) endothermic reaction and +HC) exothermic reaction and -
max2010maxim [7]

Answer:

E

Explanation:

Here in this question, what we will do is to select which of the pairs that do not correlate.

A. Enthalpy and heat content

This two terms are at par with each other. By definition, the enthalpy of a system simply is the total amount of heat content it has.

B. Endothermic reaction and +H

These two terms are at par with each other. An endothermic reaction is one in which heat is absorbed from the surroundings. It has a positive value for the heat content i.e the enthalpy is positive and thus H is positive.

C. Exothermic reaction and -H

An exothermic reaction is one in which heat is released to the environment. It usually has a negative value for the enthalpy and thus the value of H is negative.

D. High energy and High Stability

These two terms are not at par. When an entity has or is of high energy, it is usually unstable. An entity at a higher energy level will not be stable until it goes to a lower level of energy.

Thus higher energy level is associated with lesser stability while lower energy levels are associated with higher stability. The lesser the energy of an entity, the higher its stability.

This makes the option our answer.

How many milliseconds are there in 3.5 seconds
maw [93]
There are 3,500 milliseconds in a second.

One second contains 1,000 milliseconds. Three seconds contain 3,000 milliseconds. Half of three hours, therefore, would contain 3,500 milliseconds.
