Q. What is the geometry and hybridization of the carbonyl carbon in carboxylic acids and their derivatives?
Q. Write the balanced chemical equation when 3.94 gm of Mg metal was used to produce hydrogen gas.
Explain the type of nonrenewable energy resource used and their short-term and long-term effects on the environment
Find the amount of known substance present in the mixture and determine the mass of calcium carbonate present in original mixture.
Pyridine(C5H5N) is a weaker base in H2O than 2,6 lutidine (dimethylpyridine), but we observe that the pyridine-BF3 complex is more stable than the comparable lutidine-BF3. Explain the reason for this inversion in stabilities.
Find the mass of a reactant using Dalton's law of partial pressures, ideal gas law, and stoichiometry - Determine the amount of zinc metal in grams consumed in the reaction.(Vapor pressure of water at 25 o C-23.8mmHg)
How many gms of H2O must be combined to 519.5 gms of methanol at 20°C to have an osmotic pressure of 408 mm of Hg? Methanol density = 0.8921 g/mL.
What will be the resultant pressure when the stopcock is opened?
To determine the number of molecules present in air using the ideal gas law and Avogadro's number - how many molecules of each type of gas are present in 1.0 L of air at STP?
Use a drawing program to draw a beaker.
A body consists of a right circular cone whose base is 12 in. and whose altitude is 16 in. A hole 8 in. in diameter and 4 in. deep has been drilled from the base. The axis of the hole coincides with the axis of the cone. Locate the centroid of the..
Application of ideal gas law - How high can you raise the temperature of the gas without bursting the vessel?
Using a sample of 0.385 g of Alka-Seltzer, the mass of Carbon dioxide is found to be 0.122 gram. Compute and enter response (in numerical value only) to three significant figures.
