The stems and leaves of many plants contain oxalic acid (H2C2O4) or sodium oxalate. A standard analysis for determining the amount of oxalate ion (C2O4 -2) in a sample is to precipitate oxalate out with the calcium ion. The reaction often involves the following reactants. Complete the following information for this reaction. Sodium oxalate and calcium chloride

How do scientists think that gravity affected the formation of our solar system?

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.

Two people each hold the end of a rope and create waves by moving their arms up and down. this wave is best classified as a transverse wave because a) both the rope particles and the wave are moving in the same direction. b) the wave is moving up and down as the particles of the rope move horizontally. c) the wave is moving horizontally as the particles of the rope move up and down. eliminate d) the wave is moving in a parallel direction with the motion of the person's arms.
