Write out the balanced equation for the reaction that occurs when Al(OH)3 and H2SO4 react together. You do not need to make your subscripts smaller; just write them out as regular numbers. For example: Al(OH)3.
The vapor pressure of water at 20°C is 17.5 mmHg. What is the vapor pressure of water over a solution prepared from 2.00 × 102 g of sucrose (C12H22O11, molar mass = 342 g/mol) and 3.50 × 102 g water? 1. 0.51 mmHg 2. 16.0 mmHg 3. 17.0 mmHg 4. 18.0 ..
2KCLO3= 2KCL+3O2 how many grams of KCLO3 must be decomposed to produce 1.55 mol KCL and to produce 87.7g O2
How many total moles of ions are released when the following sample dissolves completely in water? 0.382 mol K2HPO4 (Assume that the hydrogen phosphate ion remains intact in solution.)
Background:Evolutionoccurs in all living organisms from the smallest bacterial cells to the mostcomplex animals. In bacterial cells evolution occurs rapidly in response toenvironmental pressures due to their simple genome and rapid reproductionrates.
Sodium hydroxide (NaOH) has a lattice energy of -887 kJ/mol and a heat of hydration of -932 kJ/mol.
Determine the formation constant, Kf, of AC5. Kf=? The solubility of AB(s) in a 1.000-M solution of C(aq) is found to be 0.152 M. What is the Ksp of AB? Ksp=?
Write balanced equations for the following, including any necessary conditions (exact temperatures or pressures are not needed).

Determine the molarity of a solution formed by dissolving 15.79 grams of CaCl 2 , calcium chloride in 200.grams of H 2 O, water?
It needs a minimum of 216.4 kJ/mol to remove an electron from a potassium metal surface. If UV light at 227 nm strikes this surface, explain what is the maximum speed (in m/s) of the ejected electrons
Thomas Jefferson Snodgrass found an unlabelled reagent bottle in his -80 C freezer. The Bottle contained a liquid. He found that the compound( compound 1) quickly evaporated when warmed to room temperature. H-NMR of the compound showed only two pe..
