A solution in which the hydroxide ion concentration is 1 x10^-2 is
Basic
A basic solution is a solution which has more hydroxide ion than the hydrogen ion. In other word the solution has a Ph greater than 7 in a Ph scale.
Answer:
D. It predicts whether or not a reaction will be spontaneous.
Explanation:
<em>What does Gibbs free energy (ΔG) predict?
.</em>
A. It predicts what the rate of the reaction will be. NO. ΔG is a thermodynamical parameter and it is not related to the kinetics of the reaction.
B. It predicts how high the activation energy is. NO. ΔG is a thermodynamical parameter and it is not related to the kinetics of the reaction.
C. It predicts if entropy will increase or decrease. NO. ΔG depends on the entropy but not the other way around.
D. It predicts whether or not a reaction will be spontaneous. YES. If ΔG < 0 the reaction is spontaneous and if ΔG > 0 the reaction is not spontaneous.
Ca(OH)2 (aq) because of elements oxygen and hydrogen
Ca(OH)2(aq)+H2SO4(aq)—→ CaSO4(s)+ 2H2O(l)
E. decomposition
hope this helps!
This is not easy. For many of the chemical elements there are several known isotopes. Isotopes are atoms with different atomic masses which have the same atomic number. The atoms of different isotopes are atoms of the same chemical element; they differ in the number of neutrons in the nucleus.
