To what pressure and temperature must one mole of Xe gas be raised in order for it to be in a state corresponding to 1.00 mol of Ar at 1.00 bar and 20.00 degrees C?
The specific heat of iron metal is 0.450 J/g-K. How many J of heat are necessary to raise the temperature of a 1.05-kg block of iron from 25.0 Celcius to 88.5 Celcius
Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons. Show the formal charges of all atoms in the correct structure.
A miniature volanco can be made in the laboratory with ammonium dichromate. When ignited, it decomposes in a fiery display. (NH4)2Cr2O7(s) ? N2(g) + 4 H2O(g) + Cr2O3(s) If 0.95 g of ammonium dichromate
under certain conditions, the combustion of charcoal (C) in the presence of o2 forms carbon monoxide (CO) according to the given balance equation.
The initial temperature of the water was 25.4 C and the final temperature of both the water and metal was 36.6 C. If the specific heat "c"
Write the half reactions and the net cell reaction for the following cell. Calculate the cell potential. S.C.E. || MnO4- (aq, 0.035 M), Mn+2 (aq, 0.022 M), pH = 4.50 | Pt(s)
The partial pressures of CH4 , N2 , and O2 in a sample of gas were found to be 143, 451 and 555 mmHg respectively. Calculate the mole fraction of nitrogen
When a solute reaches its solubility limit in a solvent, the dissolution process completely stops. When a solute has large solubility in a solvent, the two compounds are miscible to each other.
Compound A, C8H10, absorbed 3 equivalents of H2 on catalytic hydrogenation over a Pd/C catalyst to give B (C8H16). On ozonolysis, compound A gave, among other things, a ketone which was identified as cyclopentanone.
The concentration of styrene is lower in the toluene solution than in pure styrene so all bimolecular polymerization steps occur more slowly. d) the order of the reaction increases in toluene
The following experiment is used to determine the amount of helium gas in the container. In the experiment
