What final temperature in OC is required for the pressure inside an automobile tire to increase from 2.15 atm at 0OC to 2.37 atm assuming the volume remains constant?
14.0 moles of gas are in a 6.00 L tank at 22.6 C. Calculate the difference in pressure between methane and an ideal gas under these conditions.
What is the volume (L) of a sample of gas when 4.50 grams of H20(g) and 35.0g of Xe(g) at 650mmHg are mixed at 200 degrees celsius
Determination of the composition of a mixture You will be given a multi-component mixture and will be required to determine (and confirm) the %composition of the mixture, obtain a sample of each component and to verify its purity and identity.
The solubility of radium oxalate RaC2O4 in warm water is 0.0174 mols/Liter. Calculate Ksp for this compound. Radium is a 2nd column element somewhere below calcium.
Hydrogen has two naturally occurring isotopes 1H (mass= 100783), and 2H (mass= 2.0140). If the atomic weight of hydrogen is given as 1.0079, which one is the more abundant isotope

Hydrogen cyanide is produced industrially by the following exothermic reaction. 2 NH3(g) + 3 O2(g) + 2 CH4(g)---> 2 HCN(g) + 6 H2O(g) Is the high temperature needed for thermodynamic or kinetic reasons
How many grams of NaOH and H2O are required to prepare 100 g of a 28.7% NaOH by weight solution?
To account for the high electronegativity difference between hydrogen and fluorine, we reassign the orbital sites in HF in order to create an energy ladder that gives us a logical sequence for assigning electrons
Polychlorinated biphenyls (PCBs), which were formerly used in the manufacture of electrical transformers, are environmental and health hazards. They break down very slowly in the environment. The decomposition of PCBs can be represented by the equ..
