Answer:
Equivalence point titration
Explanation: Equivalent point: point in titration at which the amount of titrant added is just enough to completely neutralize the analyte solution. At the equivalence point in an acid-base titration, moles of base = moles of acid and the solution only contains salt and water.

CHECK THE COMPLETE QUESTION BELOW;
Early one morning, looking East, you see what appears to be a star. Your friend, Sheen, tells you that it's not a star, it's a planet. Which planet is it likely to be? A) neptune B) pluto C) uranus D) venus
EXPLANATION;
Venus;
Apart from the sun and the moon, Venus is described as the brightest object in the sky, it can be visualised as a very bright star in the sky when looked upon in the evening or morning.It is reffered to as the planet that is best close to Earth as far as solar system is concerned, and also the second planet from the sun with it's surface covered with volcanoes, lava plains and others
Venus is a bit smaller in size compare to the Earth and inner part of it is also similar with that of Earth.
The temperature of Venus is extremely high that it can melt metals such as lead so human cannot withstand the extreme heat.
Any physical matter that is obtained or made from plants, animals, or the ground without undergoing a chemical process is called a natural material. This is a true statement.
<h3>Features of natural materials</h3>
Natural materials are the physical matters that are made from plants, animals and ground(environment) which has not been subjected to any chemical processes for modification.
But any natural material that has undergone any chemical process which has been designed and manufactured to fulfil a particular purpose is called a synthetic material.
Therefore, any physical matter that is obtained or made from plants, animals, or the ground without undergoing a chemical process is called a natural material.

F. <em>None of the above
</em>
<em>No O atoms are present</em> as reacting substances, only O_2 and H_2O molecules.
O_2 + 2H_2O + 2e^(-) → 4OH^(-)
We must use <em>oxidation numbers</em> to decide whether oxygen or water is the substance reduced.
The oxidation number of O changes from 0 in O_2 to -2 in OH^(-).
A decrease in oxidation number is <em>reduction</em>, so O_2 is the substance reduced.
The oxidation number of O is -2 in both H_2O and OH^(-), so water is <em>neither oxidized nor reduced</em>.
