Use the de broglie's wave equation to find the wavelength of an electron moving at 4.5 × 106 m/s. show your work. note: h= plank's constant (6.62607 x 10-34 j s)

Will mark as brainliest ! how many grams of iron metal do you expect to be produced when 245 grams of an 80.5 percent by mass iron (ii) nitrate solution react with excess aluminum metal? show all work needed to solve this problem!

Describe the process that was used in this lab to create magnesium oxide, specifically identifying the type of chemical reaction. explain why the product had a higher mass than the reactant, and how this relates to conservation of matter.
