Answer:

Atom is a the smallest particle of a chemical element that can exist.

Molecules is a a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.

Particles is a minute portion of matter.

A particle can be a single atom or a molecule ( a group of atoms held together by chemical bonds).

Answer:

Atoms: a unit of the chemical element

Molecules: a group of atoms bonded together

Particles: tiny bits of matter

Yes, a particle can be a single atom.

Yes, because there's no restriction on how big or small in size particles are.

Explanation:

Atoms are in your body and even in the air you breath and molecules are with the atoms.

How many neutrons dose O^-2 have
ElenaW [278]
Oxygen is the 8th element in the periodic table. This means that oxygen has 8 protons<span> and 8 electrons. In order to get the number of neutrons you take the atomic weight in this case 15.9999~16 and you subtract it by the number of protons (16-8) (o_O)

18. Describe the relationship between kinetic energy and mass, and give an example of
lidiya [134]

Answer:

Kinetic energy is directly proportional to mass

Explanation:

Kinetic energy is directly proportional to the mass of an object and also directly proportional to the square of the velocity of that object:

E_k = \frac{1}{2} mv^2

Notice that if we keep velocity constant and only increase the mass of a object, the kinetic energy of that object would increase, as we've already emphasized the direct relationship between the kinetic energy term and the mass term.

Let's take a simple example: assume that object 1 and object 2 are both moving at the same velocity but object 1 has a much lower mass than object 2. According to the equation, object 1 has lower kinetic energy. This object can then transform all of its kinetic energy into some other form, say, heat the ground. The heat transferred will be significantly lower than by the object 2 moving at the same velocity but having a much greater mass.

Which chemical in the atmosphere of Titan (a moon of Saturn) plays the same role that water plays on the Earth by producing "rai
ololo11 [35]

Answer:

Methane (CH₄)

Explanation:

Titan refers to the largest moon of the planet Saturn, comprising a very dense atmosphere. This moon is primarily comprised of nitrogen gas, which is similar to the conditions in earth. It is extremely cold having a temperature of about ₋180°C, as a result of which it is difficult for the liquid water to exist.

Acid rain is a type of precipitation that occurs in the earth and it results in the release of a certain amount of methane gas (CH₄). Similarly, there also occurs precipitation in Titan but it releases CH₄ instead of water.  This methane is responsible for the increasing amount of temperature.

Thus, methane is a chemical that is present int the Titan's atmosphere, and it plays a similar role as in earth, the water plays by forming snow, rain, and ice.
