A chemist reacted 11.50 grams of sodium metal with an excess amount of chlorine gas. The chemical reaction that occurred is shown. 2Na + Cl2 → 2NaCl

If the actual yield of the reaction is 24.85 g of NaCl, what is the percent yield? Show your work including, the use of stoichiometric calculations and conversion factors.

According to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? view available hint(s) according to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? trigonal bipyramidal tetrahedral square planar determination of electron geometry requires information on whether the electron groups are lone pairs or bonding groups.

Use the de broglie's wave equation to find the wavelength of an electron moving at 7.3 × 106 m/s. show your work. note: h = plank's constant (6.62607 x 10-34 j s)

During an experiment, ice and water were placed in a perfectly insulated thermos flask at 0 °c. describe this system when it phase reaches equilibrium.
