An astronaut exploring a distant solar system lands on an unnamed planet with a radius of 3520 km. When the astronaut jumps upward with an initial speed of 3.21 m/s, she rises to a height of 0.525 m.
Part A
What is the mass of the planet?
A 200 ml sample of 0.200 M HBr solution is titrated with 0.2 M NaOH. Calculate the pH of the solution after 19.9 ml of NaOH have been added.
Calculate the heat absorbed by 15.0 g of water to raise its temperature from 20.0oC to 50.0oC at constant pressure. The specific heat of water is 4.18 J/g.oC
A solution contains 1.0 x 10-5 M Na3PO4. Calculate the minimum concentration of Ag+ that would cause precipitation of solid Ag3PO4.
what is the difference between the solvents used to run TLC's of polar and non-polar lipids?
If the reaction is first order in A and second order in B, what is the rate when the initial concentration of A = 2.30 mol/L and that of B = 2.03 mol/L
What is the Born-Oppenheimer approximation and why is it significant? Describe how you would use the Born-Oppenheimer approximation
What volume of 6.00 molar hydrochloric acid is needed to prepare 500.0ml of 0.100 M solution
Question- A solution contains 5.37E-3 M chromium (III) acetate and 9.00E-3 M lead nitrate. Solid sodium hydroxide is added slowly to this mixture. What is the formula of the substance that precipitates first
When 190.0 mL of 0.360 mol are added to 190.0 mL of 1.00×10?2 M AgNO3 (aq), what percentage of the Ag+ is left unprecipitated?
The dimerization of ClO is second order in ClO. Use the following data to determine the value of k and the half-life at 350 K
if molarity of a 2000ml solution is 4.0M NaCl, how many moles of NaCl are dissolved in that solution.
