Which of the following is NOT a major characteristic used to identify minerals? a. hardness c. density b. magnetism d. luster

Answers

Answer 1
Answer: Magnetism is a force which attract or repel a magnetic object like iron.
Magnetism is not a major characteristic used to identify minerals, because, every mineral do not have magnetic properties in it. Only few minerals like Iron-nickel have it and thus, it is not possible to identify a mineral using magnetism.
Answer 2
Answer: The answer would be B.)Magnetism

Alchemy is a branch of ancient knowledge that states lead metal is a form of gold metal. Which of these best explains whether alchemy is a science or pseudoscience? It is a science because ancient knowledge is often reliable. It is a science because metallurgy is known to be a branch of science. It is pseudoscience because ancient knowledge is mystical yet reliable. It is pseudoscience because each metal is known to be a unique element.

At 298 K, oxygen (O2) and ozone (O3) have different properties because their(1) atoms have different atomic numbers(2) atoms have different atomic masses(3) molecules have different molecular structures(4) molecules have different average kinetic energies

Answers

Answer: (3) molecules have different molecular structures.


Explanation:


1) Oxygen (O₂) and ozone (O₃) are allotropes of each other.


2) Allotropes are different structural forms of a same element with different structures and properties, when they are in the same state: solid, liquid, gas.


3) The bonds is what define the structure and properties of the substances, so since O₂ has only two bonds and O₃ has three bonds, the properties and behaviors of the element are different.


4) Other example of allotropes are graphite and diamond: two different forms of carbon. Both, graphite and diamond are formed only by carbon atoms, but they are bonded differently so, as you know, diamond and graphite have different properties: graphite is very soft while diamond is one of the hardest known substances.

somethingExplanation:

When stressed, mica breaks into thin sheets. This describes mica's _____. luster color streak cleavage

Answers

Answer : The correct option is, Cleavage.

Explanation :

Mica : It is silicate mineral and also known as sheet silicate because they form in different layers.

Cleavage : It is a type of mineral properties. It describes how a crystal breaks when stress apply to the crystal and breaks into a particular plane.

If the mica breaks due to stress and breaks into thin sheet, that means the mineral has cleavage.

Therefore, the correct answer is, Cleavage.

Answer:

Cleavage

Explanation:

Which physical state of matter exhibits the greatest change in volume with changes or temperature or pressure?

Answers

It’s the gas physical state that shows the greatest change in volume and changes in temperature or pressure. Because gas is the matter that is composed of loose particles but can be compressed. Since gas contains loose molecules, the molecules can freely move in a certain object, so when physical change happens, it exhibit greatest change. Gas also follow the shape of its container and can expand in order to fill its container. It has no definite volume or shape.



Stage in a star's evolution formed as the core of a main sequence star uses up its helium and the outer layers escape into space

Answers

Answer:

The stars when they release their helium and get rid of their cape and throw it into space is because it is already the end of their life

Explanation:

During a portion of its life, a bright star due to the thermonuclear fusion of hydrogen in helium in its nucleus, which releases energy that crosses the interior of the star and then radiates into outer space. When the hydrogen in the nucleus of a star is almost depleted, almost all heavier elements than naturally produced helium are created by stellar nucleosynthesis during the life of the star and, in some stars, by nucleosynthesis of supernovae when explode At the end of its life, a star can also contain degenerate matter

1. In a compound, chemical energy is contained in the (1 point)a. nuclei of the atoms.
b. unbonded electrons.
c. bonds.
d. movement of the electrons.

2. Which of the following statements is true about what happens during a chemical reaction? (1 point)
a. Bonds of the reactants are broken, and bonds of the products are formed.
b. Bonds of the reactants are formed, and bonds of the products are broken.
c. The bonds of both the reactants and the products are broken.
d. The bonds of both the reactants and the products are formed.

Answers

1. Potential of a chemical substances to undergo transformation in a chemical reaction is known as chemical energy. The chemical energy is stored in the bonds of chemical compounds.

Hence, in a compound, chemical energy is contained in bonds.

2. The process in which one or more substance known as reactants are converted to one or more completely new substances known as products are formed is known as a chemical reaction.

Hence, during a chemical reaction bonds of the reactants are broken, and bonds of the products are formed.
