(5 pts) Calculating Heat from Thermochemical Equations
Vadim26 [7]

The heat that is released by the combustion of 3.5 moles of methane is 3115 kJ/mol.

<h3>What is a thermochemical equation?</h3>

A thermochemical equation is a reaction equation that incorporates the amount of heat lost/gained.

In this case, the reaction equation is; CH4 + O2 ----->CO2 + 2H2O dH = -890 kJ/mol

If 1 mole of methane releases 890 kJ/mol

3.5 moles of methane will release 3.5 moles * 890 kJ/mol/1 mole

= 3115 kJ/mol

How does induced transmutation produce trans uranium elements ?
kifflom [539]
Answer: Artificial transmutation may occur in machinery that has enough energy to cause changes in the nuclear structure of the elements. This releases, on average, 3 neutrons and a large amount of energy. The released neutrons then cause fission of other uranium atoms, until all of the available uranium is exhausted.
