Explanation:
It is known that elements which contain same number of valence electrons when present in their neutral state then they tend to show similar chemical properties.
This is because only the valence electrons actively participate in a chemical reaction. As a result, these valence electrons determine their reactivity.
This is why, elements of same group tend to show similar chemical properties.
For example, element X and element Z have same number of valence electrons.
Therefore, we can conclude that both elements X and Z are most likely to have similar properties.
Answer:directly proportional to the pressure of the gas above the liquid
Explanation:
Answer:
PV=nRT
Explanation:
T=PV/nR
P=5.6atm n= 4 mol V=12 L R =.082Latm/K mol
T= (5.6 atm)(12 L)/(4 mol)(.082Latm/K mol)
T = 205 K = -68 C
A fundamental object that is difficult to divide into smaller bits is known as an element. An element is a substance that cannot be broken down by non-nuclear reactions in chemistry and physics. The elements are boron and oxygen, and their numbers are 1 and 2.
A pure material known as an element is made up of just one type of atom and cannot be divided into two or more different substances. A compound is a pure substance that is created when two or more substances are mixed in a specific mass ratio.
Chemistry's fundamental building block is an atom. It is the smallest fraction of matter into which electrically charged particles cannot be released. It is also the smallest piece of substance with chemical element-like characteristics.

Answer: Option (b) is the correct answer.
Explanation:
Insulator are the substances which do not conduct electricity. It is known that metals are good conductors of electricity. Whereas non-metals do not conduct electricity.
Out of the given options, silver, and calcium is a metal that means they are good conductors of electricity and are not insulators.
On the other hand, silicon is a metalloid, that is, it shows properties of both metals and non-metals. Hence, it will also show conductivity.
Phosphorus is a non-metal and therefore, it does not conduct electricity. As a result, out f the given options it will act as the best insulator.
B) Arrhenius bases
C) Brønsted-Lowry bases
D) Brønsted-Lowry acids
