What is the final volume in milliliters when 0.780 of a 39.7 (m/v) solution is diluted to 25.0 (m/v)? Express your answer numerically in milliliters.
Draw the Lewis Structure, and then specify the electron paor geometries for each of the following molecules or ions. Identify the hybridization of the central atom.
The half life of a first order reaction is 13 min. If the initial concentration of reactant is 0.085 M, what is its concentration after 8.2 minutes.
The analysis of this compound shows that it contains 41.8 percent C, 4.7 percent H, 37.3 percent O, and 16.3 percent N. Calculate the molecular formula of the compound.
Predicting the Polarizability of a Molecule. Consider the following set of data for polarizability. From what I have learned, the simplest model for predicting the polarizability of a molecule is to assume that polarizability scales with the type.
2.914 gram sample of gypsum, a hydrated salt of calcium sulfate, CaSO4, is heated at a temperature greater than 170 degrees celcius in a crucible until a constant mass is reached.
A mass of 2.50 g of hydrated copper(II) sulfate is placed in a crucible and heated. On heating, 1.59 g of white anhydrous copper(II) sulfate is left behind. Determine the ratio of water to copper(II) sulfate.
