If both the pressure and volume of a given sample of an ideal gas are doubled, what happens to the temperature of the gas in Kelvins?
a) The temperature of the gas in increased by four times its original value.
b) The temperature of the gas is reduced to one-half its original value.
c) The temperature of the gas is reduced to one-fourth its original value.
d) The temperature remains constant.
e)The temperature of the gas is increased by two times its original value.
Draw the Lewis structure of the molecule, assuming that the Cl atoms bond to a single C atom and that there is a C -C bond and two C - O bonds in the compound.
the rate constant for the second order reaction is 0.80 m-1s-1 at 10 degree celsius temperature for the given reaction
The gas remaining in the bottle slowly warms up to 285 K. What is the final pressure in the bottle for a monatomic gas, for which CV = 3R/2, and for a diatomic gas, for which CV = 5R/2?
A solution is prepared by dissolving 5.32 grams of potassium nitrite (a food preservative, as Clark Griswold would explain) into about100 ml of DI water in a volumetric flask. Enough water is then added to give a total volume of 250.0 ml. What are..
Consider the following data. 2 Ca(s) + O2(g) 2 CaO(s) H = -1270.2 kJ C(s) + O2(g) CO2(g) H = -393.5 kJ CaO(s) + CO2(g) CaCO3(s) H = -178.3 kJ Use Hess's law to calculate H for the reaction below.
