How many moles of aluminum can be produced from 1.30 moles of aluminum oxide? We need the mole ratio of Al2O3 to Al. We can find mole ratios in balanced chemical equations.
Write the equation below:

Mole ratio: For every ___ moles of aluminum oxide that decompose, ___ moles of aluminum are produced.
Use this ratio as a conversion factor to solve the problem.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
