Calculate the potential energy of a 40 gram sparrow resting on a branch 30 feet above the ground. (Hint: 1 foot = 0.305 m)
what is the molarity of a hcl solution if the reaction of 200ml of the solution with excess caco3 produces 10.5l of co2
1.) What mass of NaCl is dissolved in 200. g of water if the freezing point of the solution is -2.14 °C. Kf(water) = 1.86 ºC kg/mol
Using a ground-based telescope and a spectrometer, it has been found that sodium vapor is a major component of the thin atmosphere of Mercury. Its concentration is estimated to be about 1.0x10^5 atoms per cm^3
How will you prepare 10 mL of 0.050 M HCl from a 0.10 M solution of HCl? Assume that you use a 10-mL graduated cylinder (in which volumes can be read to the nearest 0.1 mL).
Draw a context-level data flow diagram for Weaver Pizza.
A solution contining AgNO3 is mixed with a solution of NaCl to form a solution that is 0.10 M in AgNO3 and 0.075 M NaCl. What will happen once these solutions are mixed? Ksp(AgCl) = 1.77×10-10.
balance the following reaction which occurs in acidic aqueous solution using the smallest possible integer coefficients
Problem- Hydrogen and oxygen can react to form water. Why then, is it possible to have pure hydrogen and pure oxygen present in a balloon without any reaction occurring at all
Take digestion and thoroughly explain how it is redox or the energetics (entropy, ethalpy, Calories, Gibbs?). Explain DOMs from a chemical perspective or even summarize a bunch of the real world uses of gas laws. Take a topic that sparked an inter..
Condensation polymers are made using a monomer with two functional groups which split off as the remainder of the two monomers are joined together. Often the small molecule eliminated in the process is water
If you have a 25 mL solution that contains 47 ug/dL of iron, how many grams of iron must be removed to reach a concentration of 23 ug/dL? How many moles of iron is this
