A sample of a gas in a piston/cyclinder apparatus occupies 33.1 mL at 1.14 atm and 23.3°C. If the volume of the sample is increased to 77.4 mL and the temperature changes to 39.9°C, what is the new pressure, in atm, of the sample
Certain alloys such as LaNi5 can store hydrogen at room temperature. A plate of LaNi5 containing no hydrogen is placed in a chamber filled with pure hydrogen and maintained at a constant pressure. At what depth from the surface will the concentrat..
What would be the effect of increasing the temperature on the following reaction? C2H2(g) + H2O(g) CH3CHO(g) DHrxn = -15 1 kJ 1. [CH3CHO] would increase 2. [CH3CHO] would decrease 3. [CH3CHO] would stay the same
1000g of Na2HPO4 is dissolved in 100mL of water. using mass balance and charge balance deterimne the pH of the resulting.
In our world today, aluminum is used for many items, including beach chairs and soda cans. This material was not chosen randomly but was carefully selected based on many variables. Think about where aluminum comes from, how we obtain/purify it and it..
A sample of neon gas at 1.20 atm compresses from 250 mL to 125 mL. If the temperature remains constant, what is the final pressure
The label on a one-pint bottle of water lists the following components. If the density is the same as pure water and you drink 4 bottles of water in one day, how many milligrams of each component will you obtain
3-nitrophthalic acid will be first converted into 3 nitrophthalhydrazide by reacting with 25% hydrazine. Reduction of the nitro group to an amino group with sodium hydrosulfite affords luminol.
Problem- Write the full orbital diagram for gallium and circle the electron that corresponds to the first ionization
Explain a sample of liquid mercury mass 67 g and temperature 92 C is poured into 96 g of H2O at 15 C. Compute the final temperature of the mixture assuming no heat is lost. The heat capacities of Hg as well as H2O are 27.98 and 75.33 J/mol/K, resp..
