Answer:
589.8 kJ/mol
Explanation:
Let's consider the process in which <em>the most loosely bound electron from each atom in a mole atom of gaseous calcium is removed.</em>
Ca(g) + Energy ⇒ Ca¹⁺(g) + 1 e⁻
The energy involved in this process is known as First Ionization Energy. The First Ionization Energy for calcium is 589.8 kJ/mol.
12
2×2 Hydrogen
2 Carbon
2×3 Oxygen
n = Number of Moles
S is the symbol for Sulfur
t is usually temperature
+ and - are the charges of molecules
If they're next to each other, it means it's multiplication, or combined elements (molecules)
