Answer:
Synchronous rotation is the result of tidal forces that over time slow the rotation of the smaller body until it is synchronized with its period of revolution around the larger body.
Explanation:
In a balanced chemical equation, the coefficients in front of the formulae can be used to determine the mole ratio. The mole ratio between NaOH and Al (OH) 1:1.
The ratio of the mole quantities of just about any two compounds present inside a chemical reaction is known as the mole ratio. In many chemical situations, mole ratios are employed as conversion factors among products and reactants.
In a balanced chemical equation, the coefficients in front of the formulae can be used to determine the mole ratio. A reaction's product yield may be predicted using mole ratios, as can the quantity of reactant required to produce a specific amount of result.
Al(OH) + NaOH →NaAlO + 2 HO
mole ratio between NaOH and Al (OH) 1:1
Therefore, the mole ratio between NaOH and Al (OH) 1:1.

An atom that has gained or lost electrons is called an ion. The correct answer is option b.
An ion is an atom or molecule with an uneven number of protons and electrons that produces a net electrical charge.
When an atom gains one or more electrons, it becomes negatively charged and is called an anion. When an atom loses one or more electrons, it becomes positively charged and is called a cation.
For example, when sodium (Na) loses one electron, it becomes a positively charged ion or cation:
Similarly, when chlorine (Cl) gains one electron, it becomes a negatively charged ion or anion:
Therefore, an ion is an atom that has gained or lost electrons. Option b is the correct answer.
