Why must you avoid using your hands in handling the magnesium ribbon and the crucible and cover? 2.Why must objects be cooled to room temperature before taking their weights(masses)
Estimate the age of a bottled wine that has a tritium, 3^H, content 65.% that of freshly bottled wine. Tritium decays by beta decay and has a half life of 12.3 yr.
Calculate the delta H reaction for the combustion of glucose (C6H12O6) using delta H(f knot) values. Calculate the delta H(f knot) of glucose to be used in the above calculation using the following information. (must be calculated, not looked up).
Give the structure of the organic product of the reaction of phenylacetaldehyde with the following.(give the names of the products as well).
Sodium Carbonate (NaCO3) is available in very pure form and can be used to standardize acid solutions. What is the molarity of the HCl solution if 25.3 mL of the solution is required to react with 0.256 g of Na2Co3
All chemical reactions, spontaneous and non spontaneous require an energy "push" in the form of energy of activation. why is the reaction called spontaneous if energy is required to start the reaction
What is the theoretical yield of acetic acid when 22.5 g of methanol reacts with 32.0 g of carbon monoxide in the following equation: CH3OH + CO --> HC2H3O2
A Vessel of of volume 22.4 L contains 2.0 mol H2 and 1.0 mol N2 at 273.15 K initially. All the H2 reacted with sufficient N2 to form NH3. Calculate the partial pressures and the total pressure of the final mixture.
A bottle of wine contains 12.5% ethanol by volume. The density of ethanol is 0.789 g/cm3. Calculate concentration of ethanol in wine in terms of mass percent and molality.
Glycine has the structure NH2CH2COOH. it can lose a proton from the carboxyl group and form chelate rings bonded through both the N and one of the O atoms. Draw structures for all possible isomers of tris(glycinato)cobalt(III).
What is the solubility of M(OH)2 (Ksp = 3.2e-13) in a solution buffered at pH = 9.84 solubility = M
