Mohs Scale of Mineral Hardness Hardness Mineral Absolute Hardness 1 Talc 1 2 Gypsum 2 3 Calcite 9 4 Fluorite 21 5 Apatite 48 7 Quartz 100 8 Topaz 200 According to the Moh's Scale of Mineral Hardness, the sample mineral that will scratch gypsum but not apatite is MOST LIKELY A) calcite. B) quartz. C) talc. D) topaz.

Answers

Answer: A) calcite

Explanation:

Hardness can be defined as the ability of the mineral to resist the scratch. It is the property to judge the hardness of the mineral. Mineralogist study this property of hardness using Mohs hardness scale.

Talc is the least hard substance after that gypsum, then calcite, fluorite, and then apatite.

The gypsum can be scratched by the calcite but the calcite cannot scratch apatite as it is softer than apatite.

19. Why should all measurements be done multiple times?

Answers

Answer:

Increasing precision with multiple measurements

Explanation:

The more measurements you take (provided there is no problem with the clock!), the better your estimate will be. Taking multiple measurements also allows you to better estimate the uncertainty in your measurements by checking how reproducible the measurements are.

Answer:

All measurements should be done twice to absolutely make sure that you have the correct measurement and  to avoid any mistakes if you are like building lets say a table or doing a equation. The saying is measure twice cut once

The nucleus controls the cell and contains DNA.

The nucleus transports materials inside the cell.


The nucleus holds the parts of the cell together.

The nucleus stores materials like food and waste.

Answers

Answer:

A

Explanation:

the nucleus has all the information about the cell and has the DNA

The function of the nucleus is that the nucleus controls the cell and contains DNA. Hence option A is correct.

What is DNA?

DNA stands for deoxyribonucleic acid.  DNA is defined as the molecule that contains the genetic material necessary for a creature to develop and function.  Adenine (A), cytosine (C), guanine (G), and thymine (T) are the four different types of smaller chemical molecules together known as nucleotide bases that make up the linear molecule DNA .

Nucleus are defined as an organelle with two membranes that houses the genetic material and other instructions needed for cellular functions. A positively charged nucleus and a cloud of negatively charged atoms make form an atom.

Thus, the function of the nucleus is that the nucleus controls the cell and contains DNA. Hence option A is correct.

An atom with 2 protons, 3 neutrons, and 4 electrons has a charge of

Answers

Answer: It has a charge of -2 because it has 2 more electrons than protons meaning it has a negative charge of 2 which is -2. Neutrons don't effect charge.

( +1 +1 -1 -1 -1 -1) = -2

Each proton has a charge of +1 and each electron has -1.

2(1) - 4(1) = -2

Answer:

2×-1.6×10^-19 C= -3.2×10^-19 C

Explanation:

charge on one proton is 1.6×10^-19 C

lets call this +q

therefore charge on on electron is -q

neutron does not have any charge, it is a neutral particle

Therefore the net charge will be

2q-4q= -2q

(q = 1.6×10^-19 C)

Which material is the best conductor? Which material is the best insulator? Which material would enable you to warm your hands the fastest?
LDPE

Mylar
Neoprene

Answers

Answer:

Mylar

Explanation:

The metals are good conductors of electricity whereas plastics and wood are referred to as the insulators. Here all the given options are insulators. The best insulator is Mylar. The correct option is D.

What are conductors and insulators?

The materials which allow electricity to flow through them is defined as the conductors whereas the substances which resist or do not allow the current to pass through them are called the insulators.

The human body is a best conductor and the conductor has free electrons on their surface. The insulators are solid in nature and they do not have free electrons at all.

The term Mylar is also called the plastic films. It is one of the most recognized and widely used polyester films. It is an excellent electrical insulator which can effectively trap heat.

Here LDPE is a poor conductor of electricity and HDPE is chemically inert. The latex and neoprene are forms of rubber which does not conduct electricity.

Thus the correct option is D.

Scientists can identify an element by looking at the structure of a single A.molecule. B.electron. C.neutron. D.atom.

Answers

By looking a an molecule

By definition,  the correct answer is option D. Scientists can identify an element by looking at the structure of a single atom because the number of protons can be determined, and thus its identity.

All atoms are composed of a central nucleus in which there are particles with a positive electric charge, the protons, and neutron, which is an electrically neutral subatomic particle, around which other particles with a negative electric charge that are electrons move.

Thus, the atom is electrically neutral, since the positive charge of the protons is compensated by the negative charge of the electrons.

Atoms of different elements have different amounts of protons. The atomic number (which is identified by the letter Z) indicates the amount of protons that is present in the nucleus of an atom.

This number is then responsible for defining the electronic configuration of the atom and the chemical properties of the element. Then it is possible to say that the number of protons in the nucleus, that is to say the atomic number Z, of an atom determines its identity.

Finally, the correct answer is option D. Scientists can identify an element by looking at the structure of a single atom because the number of protons can be determined, and thus its identity.
