Find the weight to the nearest kg, of the cement block. Cement weighs 1700 kg/m3. 12cm x 10cm and 40cm x 20 cm x 20cm.
It takes approximately 15 minutes to code one record. How many personnel hours would be needed to code 1,424 discharges for the month?
So i got Ka = X^2/(0.184-x) not sure what to do next.
The Ka of a monoprotic weak acid is 4.47 × 10-3. What is the percent ionization of a 0.184 M solution of this acid?
A solid steel cylinder is standing (on one of its ends) vertically on the floor. The length of the cylinder is 3.4 m and its radius is 58 cm. When an object is placed on top of the cylinder, the cylinder compresses by an amount of 5.9 10-7 m. What is the weight of the object?
A copper cube, 0.31 m on a side, is subjected to two shearing forces, each which has a magnitude F = 6.40 106 N (see the drawing). Find the angle θ (in degrees), which is one measure of how the shape of the block has been altered by shear deformation.
Find the critical number of the function. g(t) = | 4t - 9 |
At equilibrium, the concentrations in this system were found to be [N2]=[O2]=0.100 M and [NO]=0.500 M. The balanced chemical equation is N2+O2<--->2NO. If more NO is added, bringing its concentration to 0.800 M, what will the final concentration of NO be after equilibriu...
If a 4.30 M sample of A is heated to 500 K, what is the concentration of B at equilibrium? A(aq) --><--- 2B(aq) Kc=8.54 x 10^-6 at 500K ---><--- = equilibrium
At a certain temperature, the Kp for the decomposition of H2S is 0.755 H2S (g) <-- --> H2 (g) + S (g) Initially, only H2S is present at a pressue of 0.201 atm in a closed container. what is the total pressure in the container at equilibrium?
