Please show the products that would result from bromination of benzoic acid. Major and or minor if there are any.
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.
An ordinary vapor compression refrigeration cycle using R134a is to operate with a condenser at 45 C and an evaporator at -10 C. The compressor is 80% efficient.
The rate constant of a chemical reaction increases by 100 times when the temperature is increased from 400 °K to 500 °K. Assuming transiytion state theor is valid
A sample of methane gas (CH4) at 18.8 oC is heated. The pressure increases from 1.78 atm to 2.46 atm, and the volume of the sample changes from 4.09 L to 1.89 L.
As food manufacturers add vinegar to food preparations to make them tart, rather than pure acetic acid,
for each of the following three questions 25.0 ml of 0.100 m pyridine kb 1.70 x 10-9 is titrated with 0.100 m hcl. for
