Suppose a scientist repeats the Millikan oil-drop experiment but reports the charges on the drops using an unusual (and imaginary) unit called the warmomb (wa). The scientist obtains the following data for four of the drops:
(a) If all the droplets were the same size, which would fall most slowly through the apparatus?
(b) From these data, what is the best choice for the charge of the electron in warmombs?
(c) Based on your answer to part (b), how many electrons are there on each of the droplets?
(d) What is the conversion factor between warmombs and coulombs?
The vapor pressure of trichloromethane is 40.0 mmHg at -7 degrees C, and its heat of vaporization is 29.3 kJ/mol. Estimate the normal boiling point of trichloromethane.
A 150.0-g sample of a metal at 75.0°C is added to 150.0 g of H2O at 15.0°C. The temperature of the water rises to 17.5°C. Calculate the specific heat capacity of the metal, assuming that all the heat lost by the me..
determine what would be its temperature after absorption of 9.4 10-2 kwh of heat if 1.45 l of water is initially at
give the structural formula of the organic products formed (if any) when (a) ethanal and (b) propanone are treated with:
Acetylene gas (ethyne; HC=CH) burns in an oxyacetylene torch to produce carbon dioxide and water vapor, and the heat needed to weld metals. The heat of reaction for the combustion of acetylene is -1259 kJ/mol.
Use bond energy values to estimate the reaction enthalpy for the formation of ammonia from nitrogen gas and hydrogen gas. Note that N2 contains a triple bond. You will need structural formula.
