Answer:
Any substance which occupies space and has mass is known as matter. States of matter: Matter exist in three different states that are Solid, Liquid and Gas. Matter is made up of very small particles
Explanation:
Photosynthesis. Because the plants give off oxygen as a waste product. Carbon dioxide then moves from the air into the leaves of plants through tiny openings in the plants leaves.
The answer is (4). You may recall the term "radiometric dating," which refers to the dating of old artifacts by measuring proportions of certain radioactive isotopes they contain and making calculations based on their estimated half-lives. Geological formations are dated in this way.
The answer for the following question is explained below.
Therefore the total number of orbitals are " 9 ".
Explanation:
Orbital:
An orbital is a mathematical function that describes the wave-like behavior of an electron,electron pair,or the nucleons.
The total number of orbitals present in the 3rd energy level is 9.
Here,
A 3 s subshell has only one orbital.
A 3 p subshell has three orbitals.
A 3 d subshell has five orbitals.
Therefore the total number of orbitals is:
3 s = 1 orbital
3 p = 3 orbitals
3 d = 5 orbitals
total orbitals in 3rd energy level is = 1 + 3 + 5 =9
Therefore the total number of orbitals are " 9 ".
