Answer:
Explain some of the uses of metals based on their properties.
Explanation:
Metals have a shiny or metallic luster and are good conductors of heat and electricity, they can be bent and pounded in various shapes, so they can be used on cars, coins, some pipes, keys, and and a flag.
Letter C on the model titration curve corresponds to the point where pH equals the numerical value of pKa for HPr
<h3>What is a titration curve?</h3>
A titration curve is a graph of the pH of a solution against increasing volumes of an acid or a base that is added to the solution.
The pH of a solution is the negative logarithm to base ten of the hydrogen ion concentration and is a measure of the acidity or alkalinity of the solution.
The pKa is the acid dissociation constant of an acid solution.
In a titration of a strong acid and strong base, the pH at equivalence point is equal to the pKa of the acid.
The equivalence point is the point when equal moles of acids and base has reacted.
In the given titration curve, pH = pKa at point C.
In conclusion, for a titration curve of strong acid and base, at equivalence point, pH is equal to pKa of acid.

Answer: C. all particles of matter move very quickly
Explanation:
Heat is how fast the molecules are moving in something. This means even a solid's molecules are moving.
Nuclear Fusion is when two atoms (usually Hydrogen and helium because they are very light and abundant) are smashed together to form heavier elements and in the process releases massive amounts of energy. Nuclear Fission on the other hand is when a heavier atom is split apart at the nucleus and releases large amounts of energy and free neutrons and photons. (in the form of gamma rays)
Answer:
The <u>Law of Conservation of Energy</u> is the total energy of an isolated system that is remaining constant, it is conserved over time.
Explanation:
How does it relate to a chemical reaction: Chemical energy is converted to kinetic energy when a stick of dynamite explodes.
