The answer is (A) The transfer of electrons forms strong bonds between ions.
Answer:
Distillation
Explanation:
In order to turn seawater into freshwater you have to remove the dissolved salt in seawater. That may seem as easy as just boiling some seawater in a pan, capturing the steam and condensing it back into water (distillation).
The percentage composition of a substance is determined to analyze how much of an element is present in the substance and and why they needed.
The percentage composition of a compound or element in a mixture is the ratio of mass of the element to the total mass multiplied by 100.
here are many scenarios in daily life where calculating the percentage composition of something may be useful, such as:
Cooking and baking: When following a recipe, it may be necessary to calculate the percentage of ingredients used in a recipe to adjust the quantities.
Nutrition: When tracking your diet, you may need to calculate the percentage composition of macronutrients like protein, carbohydrates, and fat.
Finance: When creating a budget, you may need to calculate the percentage of income allocated to different expenses, such as housing, transportation, and food.
Chemistry: In chemistry, calculating the percentage composition of a compound is an essential step in determining its chemical formula and properties.
Manufacturing: In manufacturing, calculating the percentage composition of raw materials and finished products is important for quality control and cost analysis.
Medicine: In medicine, calculating the percentage of drugs in a medication is essential for prescribing the appropriate dose.
These are just a few examples, but there are many other scenarios where calculating percentage composition is useful.

Given the two formulas representing the same compound:
Which statement describes these formulas?
(1) Formulas A and B are both empirical.
(2) Formulas A nd B are both molecular.
(3) Formula A is empirical and Formula B is molecular.
(4) Formula A is molecular and Formula B is empirical.
Correct option is (3).
Empirical formula:-Simplest whole number ratio of various atoms present in a compound.
Molecular formula:-The formula that gives the total number of atoms of each element in each molecule of a substance.
So, (formula B) is the molecular formula, and (Formula A)is the empirical formula.
Hence, the correct option is (3).
