<span>To find the enthalpy change per mole of a substance A in a reaction between two substances A and B, the substances are added to a calorimeter and the initial and final temperatures (before the reaction started and after it has finished) are noted</span>
PV = nRT
P is pressure, V is volume in L, n is number of moles, R is the gas constant, and T is temperature in K
(1.23 atm)(10.3 L) = (n)(.08206)(29.8 + 273)
n = .5 moles x 38 grams per mol F2 = 19.4 grams F2
The answer is D. easier, higher
By the transfer of one or more electrons from one atom to another
for example,
2Na + Cl₂ → 2Na⁺Cl⁻
Na - e⁻ → Na⁺
Cl₂ + 2e⁻ → 2Cl⁻
