Dalaba swings a small block of mass M = 5.0 kg in a horizontal, circular path on a frictionless surface from a spring. One end of the spring is fixed to the center of the circle and the other end is fastened to the block, as seen in the figure. The relaxed length of the spring is 25 cm, which then stretches to a total length of R = 30 cm during the circular motion. If Dalaba measures an angular speed of ω = 3.5 rad/s, what is the spring constant for the spring k?

Calcium hydroxide reacts with hydrochloric acid according to the equation shown below. If 27.32 mL of calcium hydroxide reacts with 45.23 mL of 0.253M HCl, what is the concentration of the calcium hydroxide? Ca(OH)2 (aq) + 2 HCl (aq) ––> CaCl2 (aq) + 2 H2O (l)

Although it is important that ozone, O3(g) be found in the upper atmosphere, it is a pollutant at ground level. The EPA measures ozonecontent in air with the following reaction. O3 (g) + 2 NaI (aq) + H2O (l) → O2(g) + I2(aq) + 2 NaOH (aq) How much sodium iodide would be needed to remove 0.682 g of ozone from an air sample?
