The good year blimp travels south from dallas to houston to film a game at the nrg stadium. the balloon carries 4,000 moles of helium at an initial temperature of 15°c and a pressure of 0.95 atm. the atmospheric pressure is 0.95 atm. the blimp flies at a height is 500 meters off the ground and at a very slow velocity. the temperature of the helium reaches 25°c at its destination. how much heat, in kl, was transferred during the flight?

answer; natural resources;

(b) which contains higher levels of vitamin b, oranges or spinach?

explanation:

you can eliminate a, c, and d because they are questions based on opinions.

answer: option (a) is the correct answer.

explanation:

the measurement of hydrogen ions in a solution is known as ph.

if ph of a solution is less than 7 then the solution is acidic. if ph of a solution is greater than 7 then the solution is basic.

when the ph of a solution equals 7, then the solution is considered as neutral.

the ph of pure water is 7, therefore, it means that concentration of hydronium ions equals that of hydroxide ions.
