The label of an aerosol spray can contains a warning that the can should not be heated to over 130 degrees F because of the danger of explosion due to the pressure increase as it is heated. Calculate the potential volume of the gas contained in 500-mL aerosol can when it is heated from 25 degrees C to 54 degrees C (approx. 130 degrees F) assuming a constant pressure.
If the average speed of an oxygen molecule is 4.05multiplied by 104 cm/s at 25°C, what is the average speed of a CO2 molecule at the same temperature?
For the reaction 2HCl + Na2CO3 to 2NaCl + H2O + CO2 what volume of 0.45 M HCl solution would be needed to produce 2.5 L of CO2 at STP?
Calculate the concentration of argon in lake water at 20C. if the partial pressure of argon is 0.0090 atm and Henry's constant is 0.0015
A gas is compressed from initial volume of 5.60L to 1.23L by an external pressure of 1.00atm. During the compression the gas releases 128J of hear. What is the internal energy of the gas?
If a random sample of this element collected from the tail of a comet has an weighted average atomic mass of 10.788 amu, what is the percent abundance of the lower-mass isotope?
Calculate the heat energy released when 29.0 g of liquid mercury at 25.00 C is converted to solid mercury at its melting point
stable conformation, CH3 at 0,120d, H at 240, then on the other side has H at 0, 120, CH3 at 240d?? and is this a gauche conformation?
