How many Joules are in 2.5 kcal?
Remember that $"1 kcal"$ $=$ $"1 Cal"$ $ne$ $"1 cal"$, so this is the one where: $"4.184 J"$ $=$ $"1 cal"$. Therefore: $=> "2.5" cancel("k")cancel("cal") xx (1000...

How do you complete the following equation to illustrate the first ionization energy for one mole of magnesium atoms: $Mg:(g) + ? kcal -> Mg(g) + e^-$
All science relies on data, and to get these data, we need measurement. I don't know how they measure the ionization energy of magnesium metal, but I know that it...

An electron in a mercury atom jumps from level $a$ to level $g$ by absorbing a single photon. How do you determine the energy of the photon in joules?
Relativistic effects are present here... but I assume that the transition from level $a$ to level $g$: has $DeltaL = pm 1$ (the total change in angular momentum is...

How do you calculate the energy required to produce 7.00 mol $Cl_2O_7$ on the basis of the following balanced equation: $2Cl_2(g) + 7O_2(g) + 130 kcal -> 2Cl_2O_7(g)$?
You gots... $2Cl_2(g) + 7O_2(g) + 130*kcal rarr 2Cl_2O_7(g)$ Another way of writing this is as... $2Cl_2(g) + 7O_2(g) rarr 2Cl_2O_7(g)$ $DeltaH_"rxn"^@=+130*kcal*mol^-1$ And when we write $mol^-1$ we mean per...
