In physical chemistry and thermodynamics, the Gibbs free energy or ΔG is very important because it is the criterion for spontaneity. When the magnitude of ΔG is negative, the reaction is spontaneous. This means that the reaction readily occurs. When the magnitude is positive, the reaction is non-spontaneous. This means that in order for the reaction to proceed, you must apply external force like electricity.
For equilibrium reactions, there is a forward and reverse reaction written as: A+ B ⇆ C. Only one of those reactions is spontaneous. So, if the forward reaction is -ΔG, then the reverse reaction is the opposite which is +ΔG. The answer is letter A.
H-F because it has the largest difference in electronegativity which is 2, so it’s the most polar.
Correct answer :
C.) Radiation
Answer:
HCl is a polar covalent compound, because of electronegativity difference between Cl(3.5) and hydrogen (2). Hence in this way, the bond between HCl breaks and they formed ions in the polar solvent like water .
Answer:
the are coefficients for the atom. the tell how many there are.
Explanation:
they tell you how many atoms there are of its type.
ex. 4 C²H³. there are 4 of the c² and h³ (couldn't find a way to use subscript so used the power signs to show.)
