If you are using 15. mL of 6.0% H2O2 by mass (m/m), and you assume that the density of the solution is 1.0 g/mL and that all of the hydrogen peroxide decomposes according to the reaction:2H2O2(aq) --> 2H2O(l) + O2(g).
An electron in a cathode-ray tube is traveling horizontally at 2.60×109 cm/s when deflection plates give it an upward acceleration of 5.30 × 1017 cm/s^2.
A reaction vessel of volume 20.0 L contains 5.0 mol of nitrogen gas, 3.0 mol of hydrogen gas, and 2.5 mol of oxygen gas at 298 K initially. The gases react forming NH3(g) ammonia and H2O(l) water.
For each of the motions described below, determine the algebraic sign (+, -, or 0) of the velocity and acceleration of the object at the time specified. For all of the motions, the positive y axis is upward.
It may be assumed that the expansion is reversible and adiabatic. What was the initial pressure in the cylinder and how much work is done by the water?
A hurricane wind blows across a 7.0 m multiplied by 10.0 m flat roof at a speed of 120 km/hr. (Take the density of air to be 1.28 kg/m3.) (a) What is the pressure difference?
At a given temperature, the equilibrim constant for the system studied in this experiment is 1.4e2. Suppose 100.0ml of 2.00e-3M KSCN was mixed with 100.0ml of 2.00e-3M Fe(NO_3_)^3.
Plot the cycle on T-S and H-S diagrams then find the extraction pressure of the water, the final dryness fraction before entering the condenser.
