Answer: Option (C) is the correct answer.
Explanation:
Solid and liquid are the states of matter. Plasma is also a state of matter where a number of electrons move freely around the nucleus of an atom.
Whereas water is a liquid itself and liquid is a state of matter but water is not a state of matter.
Therefore, we can conclude that water is not a state of matter.
is not a state of matter.
Further Explanation:
Matter:
Anything that acquires space and has mass is termed as matter. It is made up of atoms. These atoms can be bonded so strongly or can be far apart from each other. The states of matter can be classified on the basis of features that are visible or can be felt.
States of matter:
1. Solid
It has a definite shape and volume. These are generally hard and have a regular arrangement of its constituent particles. These can be amorphous or crystalline. The intermolecular forces in the solids are very strong and thus the motion of particles in solid is almost negligible. Rock, wood, sugar, and diamond are examples of solids.
2. Liquid
It has a definite volume but can have the shape of any container in which it is placed. The intermolecular forces in the liquids are weaker than that in solids and thus the motion of particles in liquids is more as compared to solids. These have the property to flow. Water, mercury and bromine are examples of liquids.
3. Gas
It has neither a definite shape nor a definite volume. These are highly compressible and have an irregular or disordered arrangement of its constituent particles. The intermolecular forces in the gases are the weakest and thus the motion of particles in a gas is very high. Oxygen, hydrogen and carbon dioxide are examples of gases.
4. Plasma
It has neither a definite volume nor a definite volume. It is present in ionized gases but its uniqueness differentiates it from gases. Plasma contains free charges that make it conductive. Stars and neon signs are examples of plasma.
So solid, liquid and plasma are the states of matter. But water is an example of liquid and therefore an example of a state of matter. Therefore water is not a state of matter.

composition?
The answer to your question is D. none of the above. Ionic compounds are compounds composed of ions, charged particles that form when an atom (or group of atoms) gains or loses electrons. (A cation is a positively charged ion; an anion is a negatively charged ion.) Covalent or molecular compounds form when elements share electrons in a covalent bond to form molecules. I hope this helps.
Answer:
The answer is C. a metal and a nonmetal.
Explanation:
A covalent compound is formed when an element shares its valence electron with another element. This bond is formed between two non metals. Example:
An ionic compound is formed when one element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element and the element which accepts the electrons is known as electronegative element. This bond is formed between a metal and an non-metal. Example:
Thus an ionic compound is typically made of a metal and a nonmetal.
(1) –1 (3) –3
(2) +2 (4) +4
Answer : The oxidation number of nitrogen (N) is, (-3)
Explanation :
Oxidation number : It represent the number of electrons lost or gained by the atoms of an element in a compound.
Oxidation numbers are generally written with the sign (+) and (-) first and then the magnitude.
When the atoms are present in their elemental state then the oxidation number will be zero.
Rules for Oxidation Numbers :
The oxidation number of a free element is always zero.
The oxidation number of a monatomic ion equals the charge of the ion.
The oxidation number of Hydrogen (H) is +1, but it is -1 in when combined with less electronegative elements.
The oxidation number of oxygen (O) in compounds is usually -2, but it is -1 in peroxides.
The oxidation number of a Group 1 element in a compound is +1.
The oxidation number of a Group 2 element in a compound is +2.
The oxidation number of a Group 17 element in a binary compound is -1.
The sum of the oxidation numbers of all of the atoms in a neutral compound is zero.
The sum of the oxidation numbers in a polyatomic ion is equal to the charge of the ion.
The given compound is,
Let the oxidation state of 'N' be, 'x'
Therefore, the oxidation number of nitrogen (N) is, (-3)
