Important information about States of MatterA meteorological balloon of radius 1.0M at sea level and 20 degrees C. At it's maximum altitude the radius of the balloon is 3.0M and the temperature is -20 degrees C. Calculate the pressure inside the balloon.
A 4.000-g sample of the metal nitrate M(NO3)2 was dissolved in water and treated with excess aqueous sodium sulfate. The sulfate salt that formed weighed 3.318 g. Determine the identity of the metal.
You have samples of approximately 8mL solution with ph ranging from 4 to 10. Calculate the volume of 1M HCIO4 needed to lower the ph to 2.5.
Calculate the amount of energy released by the freezing of 13.3 g of a liquid substance, given that the substance has a molar mass of 82.9 g/mol and a molar heat of fusion of 4.60 kj/mol.
