A balloon's volume is 3.5 liters at a pressure of 4.2 atm. What was the original volume of the balloon when the pressure was 2.8 atm? * How many liters will 2.5 moles of gas occupy at 322 K and .90 atm of pressure?
What is the new pressure of a 2.5 liter balloon if the original volume was 6.2 liters at a pressure of 3.3 atm?
A 13.5 liter balloon is heated from 248 K to 324 K. What will its new volume be?

the correct answer is answer a. a mixture

no other options make sense

hope this

have a great day : )

a is the answer to this question

explanation:

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
