Answer:
That's because Earth is so much larger. If the moon were bigger enough, it might be able to “pull a Charon” and lock us in as well. “It might be that you'd have to take a vacation to the other side of the Earth to ever see the moon,” Siegler said. More than that, becoming tidally locked with the moon would change time.

Answer:
Acidic oxides, or acid anhydride, are oxides that react with water to form an acid, or with a base to form a salt. They are oxides of either nonmetals or of metals in high oxidation states.

Answer:
Mass = 2.12 g
Explanation:
Given data:
Volume of KMnO₄ = 255 mL (255/1000 = 0.255 L)
Molarity = 0.0525 M
Mass in gram = ?
Solution:
First of all we will calculate the number of moles.
<em>Molarity = number of moles of solute / volume in litter</em>
0.0525 M = number of moles of solute / 0.255 L
Number of moles of solute = 0.0525 M ×0.255 L
Number of moles of solute = 0.0134 mol
Mass in gram:
<em>Number of moles = mass/ molar mass</em>
Mass = moles × molar mass
Mass = 0.0134 mol × 158.04 g/mol
Mass = 2.12 g
The correct answer is d.
C has four valence electrons. To become an ion with a complete valence shell, it would have to
- • Gain four electrons to become C⁴⁻ or
- • Lose four electrons to become C⁴⁺
Thus, carbon is extremely unlikely to form ionic compounds.
It is false that if a question is asking about an opinion, it can be answered with science.
<h3>What is opinion?</h3>
A personal belief or assumed that is not tested or backed up by evidence is described as an opinion.
A hypothesis is typically a claim based on some form of observation or evidence. Hypotheses must be testable and, once tested, evidence-supported.
Any question that is based on opinion cannot be answered by scientific reasonings as it is not evidence based.
Thus, the given statement is false.
