Which statement correctly compares electric charge with electric current?
A.
They both require a human to make them.
B. Neither require charged particles.
C. They both require a battery and a bulb
D. They both require a movement of charged particles.
Answer:
Your answer would be D) They both require a movement of charged particles
Explanation:
In short terms both the charge and the current are made up of charged particles that are always moving, they constantly move to well... stay charged, if they stopped, then the charge would fade until there is nothing left, and if there is nothing left -it means there would be no electricity to use

Since protons (p+) with a positive charge and neutrons (n0) without a charge are located in the nucleus, what is the overall charge of the nucleus portion of an atom: positive, negative, or no charge at all? Explain.
Answer:
Positive
Explanation:
The nucleus of an atom has a net positive charge which is balanced by the negative charge of the electrons residing in the orbital of an atom. The reason why the nucleus of an atom is positively charged is because it contains two sub atomic particles;
The protons and neutrons. In terms of charge, the proton is positively charged and the neutron is neutral. This means the neutron does not partake in the charge of the nucleus. Hence the net charge of the nucleus is decided by the protons which are positively charged

TIMED TEST PLEASE HURRY!!! The development of a new experimental method is most likely to change a theory if it makes it possible to
analyze samples when they are frozen.
perform the experiment in a different lab.
obtain and analyze results more quickly.
study a larger sample size than before.
Answer:
study a larger sample size than before.
Explanation:
Science is evolving day by day and every new experiment is contradict the old experiment, giving new theories.
The advancement in the technology modifying the new experimental methods and it can change a theory if study a larger sample size than before. It is so because new experiment verify and validates larger sample size and evidences can contradict the old theory. Large sample size means more experiments and more validations.
Hence, the correct answer is "study a larger sample size than before."

An object has a volume of 825 cm3 and a density of 13.6 g/cm3. Find its
mass
The mass of an object is the product of its volume and density. The mass of a the object with a volume of 825 cm³ and a density of 13.6 g/cm³ is 11220 g.
What is density ?Density of substance is the measure of its mass per unit volume. It describes how closely its particles are packed. Density depends on the bond type, temperature and pressure.
Volume of the object is the space occupied by its particles. Volume can be expressed in L, ml, cm³, dm³ etc. Only solids and liquids has a definite volume and the volume of gases is that of the container.
Give that, volume of the object = 825 cm³
density = 13.6 g/cm³
Mass = volume × density
m = 825 cm³ × 13.6 g/cm³ = 11220 g
Therefore, the mass of the object is 11220 g.

You are trying to design a homemade ice pack. As you select the chemicals for this reaction, should you choose an endothermic reaction or an exothermic reaction? Why?
Answer:
Endothermic
Explanation:
Because Endothermic is cold and exothermic is hot and if you are using an ice pack it would be Endothermic and if you were using something that was hot it would be exothermic
Calculate the mass of 4.55x1024 molecules of sucrose
Answer:
2584 g
Explanation:
The molecular formula for sucrose is C₁₂H₂₂O₁₁, which means its molar mass is 342.3 g/mol.
First we convert molecules into moles by using Avogadro's number:
4.55x10²⁴ molecules ÷ 6.023x10²³ mol/molecules = 7.55 molNow we convert moles of sucrose into grams, using its molar mass:
7.55 mol * 342.3 g/mol = 2584 gwhat ions are formed when sodium reacts with fluorine
Answer:
One example of an ionic bond is the formation of sodium fluoride, NaF, from a sodium atom and a fluorine atom. In this reaction, the sodium atom loses its single valence electron to the fluorine atom, which has just enough space to accept it.

How does thermal energy flow between a hot or cold pack and the atmosphere?
Answer:
Heat is the transfer of energy. During energy transfer, the energy moves from the hotter object to the colder object. This means that the hotter object will cool down and the colder object will warm up. The energy transfer will continue until both objects are at the same temperature.

if surface tension relies on intermolecular forces, how could you make surface tension decrease?
(think about how and where molecules bind to each other)
Answer:
We could make the surface tension to decrease by removing and causing a disruption to the intermolecular forces(hydrogen bonds).
Explanation:
To explain this answer, we will consider an experiment whereby a paper clip is made to rest at the top surface of water inside a container/beaker.
First of all, the intermolecular forces present in water are also known as hydrogen bonds.
It's relationship with surface tension is that when there is high surface tension in the water, this high tension will allow the paper clip to rest on top of the hydrogen bonds present at the top surface in between the water molecules.
However, the surface tension will decrease when we remove or cause a disruption to the intermolecular forces (hydrogen bonds).

Use the Internet to list five examples of elements with their properties and five examples of compounds with their properties.
Answer:
here you go
Explanation:
5 elements and properties:
Boron- The chemical properties of boron are more similar to carbon and silicon than elements of its own group, although boron is more electron deficient. Boron has a high affinity for oxygen-forming borates, and reacts with water at temperatures above 100 °C to form boric acid and other boron compounds.
Carbon- As a member of group 14 on the periodic table, it is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. The most common isotope of carbon has 6 protons and 6 neutrons, and has an atomic mass of 12.0107 amu. Its ground state electron configuration is 1s22s22p2.
Nitrogen- Nitrogen gas (chemical symbol N) is generally inert, nonmetallic, colorless, odorless and tasteless. Its atomic number is 7, and it has an atomic weight of 14.0067. Nitrogen has a density of 1.251 grams/liter at 0 C and a specific gravity of 0.96737, making it slightly lighter than air.
Oxygen- is the air you breath
Nickel- Nickel is a hard silver white metal, which forms cubic crystals. It is malleable, ductile, and has superior strength and corrosion resistance. The metal is a fair conductor of heat and electricity and exhibits magnetic properties below 345°C
5 compounds and properties:
Water - Formula: H2O = Hydrogen2 + Oxygen. ...
Hydrogen Peroxide - Formula: H2O2 = Hydrogen2 + Oxygen2 ...
