Answer: Option (B) is the correct answer.
Explanation:
Elements of a group represent similar chemical properties because they contain same number of valence electrons which determines their reactivity.
Hence, elements of a group have same chemical nature or property.
A group is represented by a vertical column in a periodic table.
On the other hand, a period is represented by a horizontal line.
Thus, we can conclude that a column contains elements with similar properties in the periodic table.

Answer:
30
According to the Law of Conservation of Matter, there will be 30 atoms of product in the reaction.
LAW OF CONSERVATION OF MATTER:
The law of conservation of matter states that matter can neither be created nor produced in a chemical reaction.
This further means that the amount of matter in the reactant of a reaction must equate that of the products.
Hence, if 10 atoms of carbon (C) react with 20 atoms of oxygen (O), there will be 10 + 20 = 30 atoms of product in this reaction.
Therefore, According to the Law of Conservation of Matter, there will be 30 atoms of product in the reaction.
