Explanation:

They must obey the Law of Conservation of Mass that states that matter cannot be created or destroyed, it is conserved. Atoms are never lost or gained in chemical reactions, they are rearranged. The mass of the reactants must equal the mass of the products.

Answer:

No matter is ever “lost” during a chemical reactions. This is called the law of conservation of mass. But sometimes the way equations are written to make it look liked atoms disappeared so we balanced them so the atoms on both sides of equal.

Which concept is a basis of the Declaration of Independence?

Answers

Answer:

Explanation:

Drafting the Declaration of Independence in 1776 became the defining event in Thomas Jefferson's life. Despite Jefferson's desire to return to Virginia to help write that state's constitution, the Continental Congress appointed him to the five-person committee for drafting a declaration of independence. That committee subsequently assigned him the task of producing a draft document for its consideration. Drawing on documents, such as the Virginia Declaration of Rights, state and local calls for independence, and his own draft of a Virginia constitution, Jefferson wrote a stunning statement of the colonists' right to rebel against the British government and establish their own based on the premise that all men are created equal and have the inalienable rights of life, liberty, and the pursuit of happiness.

Through the many revisions made by Jefferson, the committee, and then by Congress, Jefferson retained his prominent role in writing the defining document of the American Revolution and, indeed, of the United States. Jefferson was critical of changes to the document, particularly the removal of a long paragraph that attributed responsibility of the slave trade to British King George III. Jefferson was justly proud of his role in writing the Declaration of Independence and skillfully defended his authorship of this hallowed document.

An atom of gold with 79 protons, 79 Electrons and 118 neutrons would have a mass number of....
A) 39
B) 158
C) 197
D) 276

Answers

Answer:

C

Explanation:

An atom of gold with 79 protons, 79 Electrons and 118 neutrons would have a mass number of  197 gold. Therefore, option C is correct.

What is mass number ?

The total number of protons and neutrons in an atomic nucleus is known as the mass number, often known as the atomic mass number or nucleon number. In atomic mass units, it is roughly equivalent to the atom's atomic mass.

Because it indicates the mass of the entire number of protons and neutrons in an element, the mass number of an element is so named. The atomic number and atomic mass of an element are typically listed in periodic tables along with the chemical symbols for each element.

The third element in the periodic table's eleventh column is gold. It is under the transition metal category. The most common isotope of gold has 118 neutrons and 79 protons together with 79 electrons.

Thus, option C is correct.

Explain the change that occurs in the molecules of water as it moves from a solid to a liquid to a gas

Answers

Answer:

Substances can change phase—often because of a temperature change. At low temperatures, most substances are solid; as the temperature increases, they become liquid; at higher temperatures still, they become gaseous.

The process of a solid becoming a liquid is called melting. (an older term that you may see sometimes is fusion). The opposite process, a liquid becoming a solid, is called solidification. For any pure substance, the temperature at which melting occurs—known as the melting point—is a characteristic of that substance. It requires energy for a solid to melt into a liquid. Every pure substance has a certain amount of energy it needs to change from a solid to a liquid. This amount is called the enthalpy of fusion (or heat of fusion) of the substance, represented as ΔHfus. Some ΔHfus values are listed in Table 10.2 “Enthalpies of Fusion for Various Substances”; it is assumed that these values are for the melting point of the substance. Note that the unit of ΔHfus is kilojoules per mole, so we need to know the quantity of material to know how much energy is involved. The ΔHfus is always tabulated as a positive number. However, it can be used for both the melting and the solidification processes as long as you keep in mind that melting is always endothermic (so ΔH will be positive), while solidification is always exothermic (so ΔH will be negative).

An ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Mechanical waves are those waves in which oscillation of matter takes place in any medium.

Electromagnetic waves are those in which electric field and magnetic field are present in the perpendicular direction to each other and also able to propogate in vaccum medium.

Both waves can transfer energy and travel in the transverse direction.

Which 2 letters have the most kinetic energy?

Answers

It looks to be x and y. Though I may be wrong.

The two (2) letters which have the most kinetic energy are: X and Z.

Kinetic energy is an energy that is possessed by a physical object or body due to its motion.

Mathematically, kinetic energy is calculated by using the formula;

[tex]K.E = \frac{1}{2} MV^2[/tex]

Where:

K.E is the kinetic energy.M is the mass of an object.V is the velocity of an object.

Basically, the kinetic energy possessed by an object is highly dependent on its mass and velocity.

From the image attached, the car gains more velocity as it travels down the slope and as such has the most kinetic energy at point X and Z.

In conclusion, kinetic energy is greatest at the bottom of a slope while potential energy is least and vice-versa.

What happens when nitrogen fills its valence shell?


A) Three electrons are gained, creating N−3.


B) Three electrons are gained, creating N+3.


C) Three electrons are lost, creating N−3.


D) Three electrons are lost, creating N+3

Answers

(A) is the correct answer

When nitrogen fills its valence shell, three electrons are gained, creating N-3. Thus, the correct option for this question is A.

What is a Valence shell?

A valence shell may be defined as the outermost shell of an atom that significantly contains valence electrons. This shell is actively involved in the pairing and sharing of elements from one another.

The atomic number of nitrogen element is 7, and its electronic configuration is [tex]1s^2, 2s^2, 2p^3[/tex]. From this electronic configuration, we come to know that the number of electrons present in the outermost shell or valence shell of nitrogen is 5.

In order to fulfill its valence shell and obtain stability, it requires three electrons to fulfill its octet. These three electrons are gained, and thus creating N−3.

Therefore, three electrons are gained, creating N−3 is the process that nitrogen performs after filling its valence shell. Thus, the correct option for this question is A.
