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.

$\boxed{{\text{C}}{\text{. Water}}}$ 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.

HELP! THIS IS A TIMED QUIZ!!

ivanzaharov [21]

Answer:

A) Age!! Its because even if the object was 1 year old or 100 years old, nothing about the impact would change. However, those other categories depict features that would definitely make an impact. For example as object that is big, fast, and hits at an angle perpendicular to whatever it is moving towards, the impact will be very lage. But if its the opposite and it was small and slow, then the impact crater would not be as large. Good luck on your quiz!!

Write the isotopic symbol for the following (show your work) a) An isotope of iodine whose atoms have 78 neutrons b) An isotope

morpeh [17]

Answer:

For a: The isotopic representation of iodine is $_{53}^{131}\textrm{I}$

For b: The isotopic representation of cesium is $_{55}^{137}\textrm{Cs}$

For c: The isotopic representation of strontium is $_{38}^{52}\textrm{Sr}$

Explanation:

The isotopic representation of an atom is: $_Z^A\textrm{X}$

where,

Z = Atomic number of the atom

A = Mass number of the atom

X = Symbol of the atom

For a:

We are given:

Number of neutrons = 78

Atomic number of iodine = 53 = Number of protons

Mass number = 53 + 78 = 131

Thus, the isotopic representation of iodine is $_{53}^{131}\textrm{I}$

For b:

We are given:

Number of neutrons = 82

Atomic number of cesium = 55 = Number of protons

Mass number = 55 + 82 = 137

Thus, the isotopic representation of cesium is $_{55}^{137}\textrm{Cs}$

For c:

We are given:

Number of neutrons = 52

Atomic number of strontium = 38 = Number of protons

Mass number = 38 + 52 = 90

Thus, the isotopic representation of strontium is $_{38}^{52}\textrm{Sr}$

What relationship exists between the mass number of an element and the isotopes of that element?

labwork [276]

The mass number plays an important role for elements and their isotopes. Mass number comes from the addition of protons and neutrons (their weight). Isotopes are the elements, but with a different number of neutrons. So in turn, by subtracting the number of protons (atomic number) from the mass, you can find the number of neutrons.
