How many grams of H2SO4 must be dissolved into 0.709 L of solution to generate a concentration of 0.303 M?
1. 2Cr(OH) 3 + 3Br 2 + 10OH - 6Br - + 2CrO 4 2- + 8H 2 O In the above redox reaction, use oxidation numbers to identify the element oxidized, the element reduced, the oxidizing agent and the reducing agent. 2. A tank ...
Consider the following reaction. CO(g) + Cl 2 (g) > COCl 2 (g) The mechanism is believed to be, (1) Cl 2 2Cl (fast equilibrium) (2) Cl + CO COCl (fast equilibrium) (3) COCl + Cl 2 > COCl 2 + Cl (slow) (4) ...

Why do the instructions call for using a saturated solution of NaOH rather than one at lower concentration? Why can we ignored in the calculation of the concentration of NaOH?
If liquid is at or above it's flash point, the flame spread rate is fast, and the entire pool is engulfed within seconds. In such a case, the liquid is already evaporating sufficiently to reach the lower flammability lim ...
Carbon-carbon single bonds in organic molecules have energies about350. kJ/mol. What is the corresponding wavelength? Could UV lamps(248 nm) be used to break these bonds?
2KMnO 4 (s) → K 2 MnO 4 (s) + MnO 2 (s) + O 2 (g) If 2.50 L of O 2 (g) is needed at 1.00 atm and 20°C, what mass of KMnO 4 (s) should be decomposed? Assume the decomposition of KMnO 4 (s) goes to completion.
Explain why the mass of the crucible and anhydrous salt is less than the mass of the crucible and the hydrate. What is the chemical formula of copper (II) sulfate?
