A synthesis would be A+B-->AB its combining, decomposition is AB-->A+B, its the breaking up of a substance.
Hello!
The answer is Evaporation!
When you add enough heat to a liquid, it boils turning into a gas. This is called Evaporation
68.7g
molar mass of Ba(137.327)x (.500)= 68.6635
.500 has 3 sig figs.
The total energy can be found by adding the different energies:
628 + 15,600 + 712
= 16.94 kJ
The Answer would be e: 3.2 g/L
<span>At STP : p = 1 atm and T = 273.15 K
molar mass Cl2 = 70.906 g/mol
d = molar mass x p/RT = 70.906 x 1 atm / 0.08206 x 273.15=3.16 g/L</span>
