A balloon is filled with gas to 165 mL at 20C. The balloon then expands to 345 mL by changing the temperature. What amount of work ( in J) is performed by the balloon?
hydrogen gas was collected over water in a eudiometer at 26 degrees c when the atmospheric pressure was 726 mm hg. What was the pressure of the hydrogen gas?
A buffer is created by combining 3.65 of with 4.72 of and diluting to a total volume of 700.0 . Determine the pH
Compare and contrast temperature and heat.When bonds or attractions are formed is the energy change given a negative or positive sign? Explain.
will the reaction occur if the partial pressures of each of the components are P(Cl2) = 4.2 bar, P(F2) = 3.3 bar, and P(ClF) = 0.092 bar. Is this more or less favorable than standard state conditions
how many millgrams of ascorbic acid (molar mass = 176.1g/mol) are in the sample, calculate the number of milligrams of ascorbic acid per 100g of citrus juice.
Calculate the spring constant of this silicone band including units. I know Hooke's law is F=-KX, where F is force, -K is the consent of the spring which I need to find and X is the displacement from relaxed position, but i'm giving the oscillatio..
