How much energy is needed to warm 0.500 g of silver from 25.0 degree C to 27.5 degree C? The specific heat of silver is 0.24J /g. degree C
What IR stretches (and ranges) will occur in? What IR stretches (and ranges) will occur in an aldehyde, but not an alcohol or ketone and IR stretches (and ranges)
Microwave ovens use microwave radiation to heat food. The microwaves are absorbed by moisture in the food, which is transferred to other components of the food. As the water becomes hotter
Neat, aliphatic, primary amines show two absorptions between 3400 to 3330 cm-1 and 3330 to 3250 cm-1 due respectively to asymmetrical and symmetrical stretch. Stretch at 3300 cm-1. Why do tertiary amines not absorb in this region of the spectrum?
calculate the moles of CO2 you would theoretically expect from 0.203 grams of an alka-seltzer tablet at 700. torr and 285. K.
Find the heat of combustion in kJ/g for each gas. These values are valid at 25°C, where the water produced by the reaction is in the liquid state.
Liquid nitrogen trichloride is heated in a 2.88-L closed reaction vessel until it decomposed completely to gaseous elements. The resulting mixture exerts a pressure of 766 mmHg at 75°C.
Determine the electron geometry (eg) and molecular geometry (mg) of CH3+1.
Important information about balanced chemical equation, 1. If 1 mole of Al4C3 has a mass of 144g and carbon has a mass of 12g, what is the atomic mass of aluminum?
Explain what it means that the atomic mass of naturally occurring Ag, is a mixture of its two isotopes forms, is 107.868 u.
Calculate the Calorimeter Constant if 25 g of water at 53C was added to 25 g of water at 25C with a resulting temperature of 35C?
A solution containing the two compounds exhibits absorbances (using a 1.00cm cell) of 0.726 and 0.544 at 267 and 312nm, respectively. What are the concentrations of A and B in mg/mL? Note: The aborptivity values are given in units of L/g.cm.
