Which particle diagrams represent mixtures of a diatomic element and a compound?

A) The equation represents a physical change, with the product and reactants having different chemical properties. B) The equation represents a physical change, with the product and reactants having identical chemical properties.

Which type of matter is represented by the particle diagram?

Elements and compounds can be represented using particle diagrams, which is a box in which colored balls are draw to represent atoms or molecules. These diagrams can represent elements and compounds, as well as their molecular composition by the types of balls and how they are connected.

How do you draw a particle diagram of elements and compounds?

How do you identify elements in a particle diagram?

41 Which particle diagram represents one substance in the gas phase? 3 gases are spread out they must be the same compounds or elements to be one substance

What is a particulate diagram?

• Particle Diagrams used to show the particles (atoms or molecules) in a substance. • They’re drawings (diagrams) that show the particles in a substance. • We draw particle diagrams for solids, liquids and gases.

What are mixtures of elements?

Note that a mixture: consists of two or more different elements and/or compounds physically intermingled, can be separated into its components by physical means, and. often retains many of the properties of its components.

What are the examples of diatomic elements?

Diatomic molecules are composed of only two atoms, of either the same or different chemical elements. Common diatomic molecules include hydrogen (H2), nitrogen (N2), oxygen (O2), and carbon monoxide (CO).

How many types of particles are there in a mixture?

In an element, all the atoms (particles) are the same. In a compound, there is more than one type of atom, chemically joined. In a mixture, there is more than one type of substance, but they aren’t chemically joined.

What are the 2 types of mixture?

There are two main categories of mixtures: homogeneous mixtures and heterogeneous mixtures. In a homogenous mixture all the substances are evenly distributed throughout the mixture (salt water, air, blood).

What are 2 examples of a mixture?

Examples of Mixtures
  • Crude oil: A mixture of organic compounds (mainly hydrocarbons)
  • Seawater: A mixture of various salt and water.
  • Air: a mixture of various gases like oxygen, carbon dioxide, nitrogen, argon, neon, etc.
  • Ink: A mixture of coloured dyes.
  • Gunpowder: A mixture of sulfur, potassium nitrate and carbon.

What are examples of mixtures in chemistry?

Examples of Mixtures
  • Sand and water.
  • Salt and water.
  • Sugar and salt.
  • Ethanol in water.
  • Air.
  • Soda.
  • Salt and pepper.
  • Solutions, colloids, suspensions.

What kind of mixture is formed when larger particles?

A suspension is a heterogeneous mixture in which some of the particles settle out of the mixture upon standing. The particles in a suspension are far larger than those of a solution and thus gravity is able to pull them down out of the dispersion medium (water).

What are 2 types of heterogeneous mixtures?

Scientists recognize two types of heterogeneous mixtures; they are known as suspensions and colloids.

What are two types of homogeneous mixtures?

Examples of homogeneous mixtures include air, saline solution, most alloys, and bitumen. Examples of heterogeneous mixtures include sand, oil and water, and chicken noodle soup.

When two or more materials are combined a mixture is formed?

A mixture is created when two or more different substances are physically combined and can be separated back into its original substances. A chemical reaction occurs when two or more substances are combined to form a new substance and cannot be separated back into its original substances.

What kind of mixture is formed when larger particles settle out when left underserved?

chapter 9 science
A B
suspension a heterogeneous mixture containing a liquid in which larger particles eventually settle out.
coagulation process that destroys collid structure; can be used to reduce a colloidal form of air pollution.

What kind of mixture is formed when large particles settle down when left undisturbed?

Suspension
Suspension is a heterogeneous mixture. The particles of a suspension can be seen by the naked eye. The particles of a suspension scatter a beam of light passing through it and make its path visible. The solute particles settle down when a suspension is left undisturbed, that is, a suspension is unstable.

What substance is made by mixing two elements without being chemically combined?

A mixture is a material system made up of two or more different substances, which are mixed but not combined chemically. A mixture refers to the physical combination of two or more substances in which the identities of the individual substances are retained.

What is formed when particles of two or more substances are distributed evenly among each other *?

A solution appears to be a single substance, but it is actually a homogeneous mixture composed of particles of two or more substances that are distributed evenly among each other.

What happens to the two mixtures when you mix them?

In simplest terms, a chemical change (or chemical reaction) occurs when two substances are mixed together and transform into a third substance. Not all substances react chemically when mixed together, however. For example, some substances, when mixed together, remain simply a mixture of those two substances.
