Based on the stereochemistry of the addition of bromine to cinnamic acid write the structure of dibromide product(s) that you think will be formed as the result of the reaction of Z-2-pentene with bromine. Also draw the structure of the dibromide product(s) predicted when the E-2-pentene react with bromine.
Explain how to correct for the partial of water vapor when calculating the partial pressure of a dry gas is collected over water?
An aqueous solution of CaCl2 has a vapor pressure of 83.0mmHg at 50 C . The vapor pressure of pure water at this temperature is 92.6mmHg .
A hypothetical element Z has two stable isotopes: Z-46 = 46.046 u 64.08% Z-51 = 50.826 u 35.92% What is the average atom weight of the element?
A container (8.65-L ) holds two gases mixture at 31 °C. The partial pressures of gas X and gas Y, respectively, are 0.206 atm and 0.867 atm. If 0.200 mol a third gas is added with no change in temperature or volume determine the total pressure be..
