The standard enthalpy of atomization of an element is the energyrequired to convert 1 mole of an element in its most stable form at25 centigrade to 1 mole of monatomic gas. Given that the standardenthalpy of atomization for sodium is 108.4 kJ mol-1,calculate the energy in kilojoules
The half life for the first order decay of 99Mo is 66.02 hours. How long will it take for a sample of 99Mo to decay
What is the possible chemical explanation for this? I understand that a reaction using a thiamine catalyst at room temperature for 48 hours may lead to lower yield due to catalyst decomposition, but I'd like to know a more technical explanation.
Predict the products when 1-propanol is heated in the presence of an acid. please include a picture of it. Really appreciate it.
Some bacteria are able to harvest 1000-nm light. What is the energy (in kilocalories or kilojoules) of a mole (also called an einstein) of 1000-nm photons?
Determine the activation barrier for the reaction.
A student heated 1.0L of ethanol (density 0.789 g/L) with 1.0 mL ethanoic acid (density 1.049 g/mL) with a sulfiric acid catalyst and noticed a vinegar-like smell to the product as well as a fruity medicinal smell.
