  • gas chemistry problem?

    An air bubble rises through the ocean froma depth of 1000 feet to the surface. As it rises, the pressure decreases from 30 atm to 1.0 atm. At a depth of 1000 feet, the volume of the bubble is 5.00mL. Assuming that the temperature of the gas inside the bubble does not change, and that it does not gain or lose mass, what is the volume of the bubble just before it reaches the surface (at 1 atm)?

  • i missed a period in june but had one in july and hcg levels are in between pregnant and not, am i pregnant?

    i missed a period in june and my urine test came up partially positive so i had blood drawn and it was also partially positive, the next day i started my period but i still had to go to the doctors to find out what was going on. So i went today and the urine test was negative, but he said he had never seen both tests show partially positive so i have to have an ultrasound..... am i pregnant or not??
