Answer:

Friction

Explanation:

Energy is lost to heat as the object overcomes kinetic friction as it slides up the ramp. The energy loss is equal to the work done by the friction force.

Explanation:

Answer:

Radiocarbon dating works by comparing the three different isotopes of carbon. Isotopes of a particular element have the same number of protons in their nucleus, but different numbers of neutrons. This means that although they are very similar chemically, they have different masses.

Nitrous Acid [tex]N_{2}O_{3}[/tex]

Nitrogen is in the +3 oxidation state in N2O3. Nitrous acid is a weak acid.

The compound contains nitrogen with an oxidation number of +3 is N₂O₃ and nitrous acid HNO₂. Nitrous acid is a weak acid.

The term oxidation state is defined as the total number of electrons that an atom either gains or loses in order to produce a chemical bond with another atom. The oxidation state is also called as oxidation number.

The formula for calculating oxidation states would be : The Highest Oxidation State for a Transition metal = Number of Unpaired electrons + Two s-orbital electrons.

The compound contains nitrogen with an oxidation number of +3 is N₂O₃ because it can acquire three electrons to form a chemical bond and to complete its outermost orbit (octet).

Thus, The compound contains nitrogen with an oxidation number of +3 is N₂O₃ and nitrous acid HNO₂.

Answer:

The form of energychemical energy

Answer:

Each ion, or atom, has a particular mass; similarly, each mole of a given pure substance also has a definite mass. The mass of one mole of atoms of a pure element in grams is equivalent to the atomic mass of that element in atomic mass units (amu) or in grams per mole (g/mol).

Explanation:

The relationship between the given terms is provided below throughout the below segment.

We can say that,

→ [tex]1 \ mole \ in \ gram \ of \ an \ element = Atomic \ mass \ of \ an \ element[/tex]

Answer:

A chemical change happens when one chemical substance is transformed into one or more different substances, such as when iron becomes rust.

Explanation:

Answer: when one chemical substance is transformed into one or more different substances.

Answer:

The phases of the species should be indicated by the spacing and distribution of the particles in the diagram

Explanation:

Evaporation would be a phase change from liquid to gas where intermolecular forces are broken CCl4 (l) -> CCl4 (g)

Diagram is attached below

We have that  from the diagram that when CCl4(l)  is placed in a previously evacuated container at 30°C , and some of the CCl4(l) evaporates that the molecules of CCl4(g)  becomes loosely held and apart from while in its closely held in its liquid state.

From the question we are told

CCl4(l) is placed in a previously evacuated container at 30°C , and some of the CCl4(l) evaporates. In the box below, draw a particulate diagram to show the species in the container after some of the CCl4(l) has evaporated. The phases of the species should be indicated by the spacing and distribution of the particles in the diagram. Some of the species shown in the legend will not be used.

Generally

We will see from the diagram that when CCl4(l)  is placed in a previously evacuated container at 30°C , and some of the CCl4(l) evaporates that the molecules of CCl4(g)  becomes loosely held and apart from while in its closely held in its liquid state

Thermal Energy

When a rise in temperature causes atoms and molecules to move faster and collide with each other. The energy that comes from the temperature of the heated substance is called thermal energy.

Answer:

2, 3, 4, 5

Explanation:

Pretty sure protons matter a lot unless in acid and bases but ignore this. Atoms mostly empty space as electrons are reeeeeeeeeeaaaallllllyyyy far apart. number of electrons change it is an ion and neutrons change pretty sure its an isotope. Electrons are stupidly small and fast so they don't really count towards the weight. Most mas comes from neutrons and protons in the nucleus

Answer:

2,3,4,5

1st is wrong cuz if u change the number of proton it would change the atomic number which results in different element

6th is wrong because most mass of the atoms come from neutrons and protons collectively so if it would have said THE ATOMS MASS MOSLTY COMES FROM NUCLEONS then u could mark it right

Axis

Anatomy

In anatomy, the second cervical vertebra of the spine is named the axis or epistropheus. By the atlanto-axial joint, it forms the pivot upon which the first cervical vertebra, which carries the head, rotates.

Rotation

A rotation is a circular movement of an object around a center of rotation. A three-dimensional object can always be rotated about an infinite number of imaginary lines called rotation axis. If the axis passes through the body's center of mass, the body is said to rotate upon itself, or spin.

Revolution

In political science, a revolution is a fundamental and relatively sudden change in political power and political organization which occurs when the population revolts against the government, typically due to perceived oppression or political incompetence.

Elliptic orbit

In astrodynamics or celestial mechanics, an elliptic orbit or elliptical orbit is a Kepler orbit with an eccentricity of less than 1; this includes the special case of a circular orbit, with eccentricity equal to 0. In a stricter sense, it is a Kepler orbit with the eccentricity greater than 0 and less than 1.
