Suppose a tank is filled with A2(g) so that initial pressure is 0.8688 atm at temperature of 298K. Some of the A2(g) dissociates and when the system reaches equlibrium the total pressure in the tank is 1.275 atm. Calcula ...
Why do the instructions call for using a saturated solution of NaOH rather than one at lower concentration? Why can we ignored in the calculation of the concentration of NaOH?
A watch glass and Filter paper weighing 41.060g was used to collect the CuSCN precipitate in this experiment. After drying, the precipitate, watch glass, and filter paper weighed 42.525g. If the sample alloy used for the ...

The following sequence of reactions occurs in the commercial production of aqueous nitcric acid: 4NH3(g)+ 5O2(g) -> 4NO2 (g) + 6H2O(l) ΔH = -907 kJ 2NO(g) + O2(g) ? 2NO2(g) ΔH= -113 kJ 3NO2 + H2O(l) -> 2HNO3(aq) + NO(g) ...
Consider the following reaction. A (g) + B (g) → C (g) + D (g) *In one experiment the concentration of A (g) was monitored in the presence of a large excess of B (g) ( [B] o = 0.750 M ) . Time (s) [A] (mol/L) 0.00 6.00 ...
One liter of nitrogen (N 2 ) and one liter of carbondioxide (CO 2 ), initially at one atmosphere pressure, are forcedinto a single evacuated 500 mL vessel. What is the total pressure, in atmospheres,if the temperature re ...
When the concentration of A in areaction was changed from 1.20 M to 0.600M, the half -lifeincreased from 3-00min to 6.0 min at 250C. Calculate theorder of reaction and the rate constant.
Why is (NH 4 ) 2 CrO 4 a molecular compound if ionic is metal + nonmetal and molecular is nonmetal+nonmetal? The Cr is a metal and the NH4 and O4 are non metal so it is metal+non metal but why cant it be ionic instead o ...
