Metallic magnesium reacts with steam to produce magnesium hydroxide and hydrogen gas. If 17.1 g of Mg are heated with 9 g of H2O, what is the limiting reactant.
you dissolve 650.0 g of sugar c12h22o11 in 726 ml of water. the density of wat is 1.00 gml.a. calculate the molarity of
Predict the order of melting point, from low to high, for the following compounds, based on intermolecular forces: CaF2 H2O H2S CH2Cl2 N2
Succinic acid, an intermediate in the metabolism of food molecules, has molecular mass = 181.1 amu. When 1.926 g of succinic acid was dissolved in water and titrated, 65.20 mL of 0.5000M NaOH solution was required to neutralize the acid.
explain the apparent paradox. although the addition of one equivalent of HX to an alkyne is more exothermic than the addition of HX to an alkene, an alkene reacts faster
Describe how the pseudo rate constant, k', is determined from the experimental data? Also describe how k, the true rate constant, is determined from the experimental data
The reaction 4PH3(g) -> P4(g) + 6H2(g) is found to be first order in PH3 with a rate constant of 1.6*10^-2 sec^-1 at 650 C. a)Give the rate law (rate equation) for the reaction and explicitly state how the reaction rate in this case would be defin..
