A balloon is filled with 80 liters of gas on a day where the temperature was 34 degrees at sea level which is 101.3 kPa and released. As the balloon rises to a certain altitude, the temperature drops to 0 degrees celsius and the balloon doubles in volume. What is the atmospheric pressure at that altitude? Explain the phenomenon you observe in the diagram. Provide as many details as possible to your explanation A student named a particular compound 2-ethyl-3-methyl-2-butene. Assuming that the student's choice actually corresponded to the correct distribution of the double bond and the substituents, what is the correct IUPAC name for this compound In the diagram below of triangle PQS, S is the midpoint of PR and T is the midpoint of QR. If ST = 5x - 22, and PQ = 3x + 19, what is the measurement of PQ? If the amplitude of a sound wave is increased by a factor of four,how does the energy carry by the sound wave in each time interval change? The Marked price of a jacket at a dealer's shop is 2400. The dealer allows a discount of 15% to the retailer. As the company's policies the marked price of the retailer should be the same as the dealer's marked price. What SP should the retailer fix for the jacket? What would its final price be if 10% VAT is imposed? What would be the actual gain of retailer?Ans 2280,2502,240 what is the important of social study? in a sale, normal prices are reduced by 10%nathalie bought a pair of shoes in the sale for 54what was the original price of the shoes Lily's car has a fuel efficiency of 8 liters per 100 kilometers.

Dehydration synthesis leads to WICH formation A review of combination Here's a little something that will tease your brain. I doubt someone will answer this A car takes a full round of journey in a roundabout with constant speed, as the driver got confused with the route. Can we consider it as a uniform motion? Why? Please revise this sentence: "Only then did I realize how annoyed a cat must have got when it couldn't catch the mouse, and eventually how happy a cat can get when the mouse dies without it trying."

The weekly amount of money spent on maintenance and repairs by a company was observed, over a long period of time, to be approximately normally distributed with mean $400 and standard deviation $20. How much should be budgeted for weekly repairs and maintenance to provide that the probability the budgeted amount will be exceeded in a given week is only 0.1? Which expression is equivalent The following data represents the number of days absent and the final grade for a sample of college students in a general education course at a large state university.
