The correct answer is D. Pluto

Explanation

According to the characteristics presented for the celestial bodies, such as the impossibility of cleaning its orbit by its small size and a rock surface without rings, the one that best suits these characteristics is Pluto. This can be explained as in 2006 Pluto was claimed to be a dwarf planet, which means it shares similarities with other planets but due to its size it does clear objects from its orbit and therefore it is not a planet. Also, Pluto is composed of rocks and ice, but different from other bodies such as Saturn it does not have rings. So, the correct answer is D. Pluto.

0.023 M solution of perchloric acid
kogti [31]
The original question is to find the pH and the pOH of 0.023 M of perchloric acid.

Answer:
pH = 1.638
pOH = 12.362

Explanation:
1- getting the pH:
pH can be calculated using the following rule:
pH = -log[H+]
Since the given solution is an acid, this means that [H+] is the same as the concentration of the solution.
This means that:
[H+] = 0.023
Substitute in the above equation to get the pH as follows:
pH = -log[0.023]
pH = 1.638

2- getting the pOH:
We know that:
pH + pOH = 14
We have calculated that pH = 1.638.
Substitute in the above equation to get the pOH as follows:
pOH + 1.638 = 14
pOH = 14 - 1.638
pOH = 12.362

Hope this helps :)

The equation that conforms with the particle model is 4C + 6O2 ----> 4CO2 + 2O2.

<h3>What is a chemical reaction?</h3>

The term chemical reaction has to do with the combination of substances to give products. We know that reactants and products must follow the law of conservation of mass.

Hence, the equation that conforms with the particle model is 4C + 6O2 ----> 4CO2 + 2O2.
