Answer:it’s c
Explanation:
I just took a quiz
A point charge is a model that represents the charge is acting uniformly unit surroundings what other characteristic does a point charge have " it has no volume"
What is point charge?A hypothetical charge at a specific space would be known as a point charge. Even though an electron is often referred to as a point charge, its size might be determined by just a length scale called the electron radius.
What is charge?Wave amplitude at a specific distance is charged (r). It could be described as energy, although a force is a much more common way to do it.
A point charge is a model that represents the charge is acting uniformly unit surroundings what other characteristic does a point charge have " it has no volume"
therefore, the correct answer will be (C).

Describe how advances in atomic theory led to the use of atomic energy.
Answer: Atomic theory established that all matter is made of tiny particles, a discovery that led to amazing scientific breakthroughs in areas from modern chemistry to nuclear energy
Explanation:
When writing a chemical equation, the number of atoms on the reactants do NOT need to equal the number of atoms on the products.
true
false
Answer:
False
Explanation:
When writing the chemical equation number of atoms on the reactant side must be equal to the number of atoms on right side because according to law of conservation of mass, mass can neither be created nor destroyed but change from one to another form, thus total mass remain same on both side of equation.
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
This law was given by French chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
For example:
In given photosynthesis reaction:
6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂
there are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.

A rock is found in an area that once had an active and has since been affected by erosion. The rock has individual black and white crystals that are easy to see. Which other description fits the rock?
Answer:
exposed to air and water
Explanation:
A rock found in an area that was active once and affected by erosion is a form of sedimentary rocks. Sedimentary rocks can be present in black and white crystals form.
The other description fits the sedimentary rocks is exposed to air and water. Sedimentary rocks are formed by the process of erosion and weathering that include the exposure of rocks to the wind and rain or water, that break down large pieces of rocks into smaller.
Hence, the correct answer is "exposed to air and water".
The other description of the rock is that it's cooled in the volcano. The type
of rock is known as the igneous rock.
Igneous rock is produced when the volcano erupts and is cooled near the
Earth's surface. We were told that the rock was affected by erosion which
took it deep into the soil and became inactive.
High temperature and pressure led to it erupting as a volcano which
explains why it has the black and white color due to heat exposure.

A cube of iron at 20. Degrees C is placed in contact with a cube of copper at 60 degrees C. Which statement describes the initial flow of heat between the cubes?
Answer:
D) Heat flows from the copper cube to the iron cube.
Explanation:
These are the options for the question
A) Heat does not flow between the cubes.
B) Heat flows in both directions between the cubes
C) Heat flows from the iron cube into the copper cube.
D) Heat flows from the copper cube to the iron cube.
From the knowledge of
second law of Thermodynamicss, which says heat moved from higher temperature to lower temperature region, and termal conduction,energy such as heat will only flow from higher temperature to lower temperature, which means the heat will move from higher concentration to lower Concentration. As the cube of copper at 60 degrees is heated the atoms beginnings to vibrate as it acquire energy then moves and flow to the lower temperature part.
Therefore, Heat flows from the copper cube to the iron cube.
An element (either a neutral atom or an ion) can be distinguished from any other element by 1. The number of electrons it has. 2. The number of protons it has. 3. The number of neutrons it has. 4. The combined number of protons and neutrons it has
Answer:
2. The number of protons it has
Explanation:
1. The number of electrons
This is incorrect because atoms and ions can have the same number of electrons from electron gain or loss
2. The number of protons it has
All atoms of an element have the same number of protons and every element has a different number of protons in its atoms. This is the correct option.
3. The number of neutrons it has
Examples includes carbon-12, nitrogen-13 and oxygen-14. They all have the same number of neutrons. This option is wrong
4. The combined number of protons and neutrons it has
Isobars are atoms that have the same mass number (proton and neutron). Examples are S-40, Cl-40, Ar-40 etc This option is wrong
Which of the following is not a polyner glucose tryglicerides starch and dna
Answer:
Glucose
Explanation:
A polymer is a macromolecule composed of many repeating subunits.
Triglycerides are made of three fatty acids and glycerol, they are polymers of fatty acid molecule monomers.
DNA molecules are polymers of nucleotides.
Glucose is a monomer. When it polymerizes it forms starch or cellulose.
Therefore, the only option that is not a polymer is glucose.

An EMR photon is 0.01 m long what is it's frequency and what type of wave is it?
Answer: Electromagnetic radiation can act both as a wave or as a particle or photon. Electron radiation is released as photons or bundles of light energy that travel at the speed of light as waves. Therefore electromagnetic radiation can be described by wave theory, where it is represented by its speed, frequency and wavelength.
What part of the atom determines the identity of an atom?
Every element has a unique atomic number. The atomic number is equal to the number of protons within the nucleus of every atom of the element. There are actually no two elements with the same number of protons within their atoms, so this numbers helps to identify an element.
In summary, the one thing that can determine an atom's identity would be the number of protons.
Hope this helps!
The number of protons (atomic number), which determines the chemical characteristics of the atom (element type), determines the nucleus, which is made up of protons with a positive charge and neutrons without a charge. The number of protons determines the identity of an atom.
The "basic building blocks of matter" are described as atoms. It is the lowest component of matter that possesses chemical elemental characteristics. Atoms do not exist alone; rather, they combine to create ions and molecules, which then join together to form matter in huge quantities.
The atomic number (Z) of an atom is the number of protons in the nucleus. The identification of the atom is determined by the element's value, which is its distinguishing characteristic.

Which statement describes the electron sharing between hydrogen and fluorine?
A. Hydrogen shares seven electrons, while fluorine shares one electron.
B. Hydrogen shares one electron, while fluorine shares seven electrons.
C. Hydrogen and fluorine share one electron with each other.
D. Hydrogen and fluorine share seven electrons with each other.
Answer:
C
Explanation:
Hydrogen has one electron in its outermost shell, while fluorine has seven electron in its outermost shell, hence both hydrogen and fluorine needs a single electron to complete its outermost shell. That's why there is a single bond between hydrogen and fluorine.
Both hydrogen and fluorine share one electron with each other for the completion of their outermost shell. So the correct option is C.
What is covalent bonding?
In chemistry, the interatomic linkage that can be formed between atoms of the same or different elements and is due to the sharing of an electron pair between two atoms is called a covalent bond.
The kind of bonding is the result of an electrostatic force of attraction of their nuclei for the same electrons so that they can complete their octet. When the bonded atoms have lower total energy than that of widely separated atoms, a covalent bond is formed m
The inorganic substances hydrogen, nitrogen, chlorine, water, and ammonia (H2, N2, Cl2, H2O, NH3) and also all the organic compounds are the molecules that have covalent bonding. In the case of structural representations of molecules, this type of bonding is indicated by solid lines that connect pairs of atoms.
Therefore the correct option is C.
