The answer is Velocity and potential energy. Kinetic energy is the total energy of a system or an object in motion and requires movement.

When in water, MgCl2 dissociates into magnesium ions and Cl- ions and NaOH into Na and OH ions. The equation is as follows:
MgCl2 = Mg2+ + 2Cl-
NaOH = Na+ + OH-
The initial concentrations are as follows:
[Mg2+] = .220(<span> 2.47x10^-4) / .220+.180 = 1.36x10^-4 M Mg2+
</span>[OH-] = .180 (3.52x10^-4) / .220+.180 = 1.58x10^-4 M OH-
Answer:
B
Explanation:
The general equation for the reaction of a carboxylic acid with an alkanol to form an ester is shown below;
RCOOH + ROH ------> RCOOR + H2O
Hence; the reactant carboxylic acid can only be the compound (CH3)2-CH-CH2-COOH in accordance with the general reaction equation shown above.
Hence the reaction is;
(CH3)2-CH-CH2-COOH + CH3-CH2OH -------> CH3CH2 OCO-CH2-CH-(CH3)2
<h2>Answer:</h2>
Option D is correct. It is independent of the reaction pathway.
<h2>Explanations:</h2><h2>What is Hess's law?</h2>
Hesslaw states that the enthalpy change of a reaction does not change regardless whether the reaction takes place in a single or multiple reaction pathways.
This shows that the total entalpy change of a reaction does not depend on the reaction pathway.
