All matter is made up of very small particles called atoms. Atoms are the building blocks of all matter. When a substance contains only one type of atom, it is called an element. Each element has a special name and unique properties that are different from all the rest of the elements.

Chemical composition refers to the arrangement, type, and ratio of atoms in molecules of chemical substances. Chemical composition varies when chemicals are added or subtracted from a substance, when the ratio of substances changes, or when other chemical changes occur in chemicals.

A composition of matter is an instrument formed by the intermixture of two or more ingredients, and possessing properties which belong to none of these ingredients in their separate state. A newly synthesized chemical compound or molecule may be patented as a composition of matter.

When we speak of a pure substance, we are speaking of something that contains only one kind of matter. This can either be one single element or one single compound, but every sample of this substance that you examine must contain exactly the same thing with a fixed, definite set of properties.

The two main types of pure substances are compounds and elements. They consist of a single type of particle or compound.

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).

Here are a few more examples:

• Smoke and fog (Smog)
• Dirt and water (Mud)
• Sand, water and gravel (Cement)
• Water and salt (Sea water)
• Potassium nitrate, sulfur, and carbon (Gunpowder)
• Oxygen and water (Sea foam)
• Petroleum, hydrocarbons, and fuel additives (Gasoline)

Saltwater acts as if it were a single substance even though it contains two substances—salt and water. Saltwater is a homogeneous mixture, or a solution.

In chemistry, a mixture is a material made up of two or more different substances which are not chemically combined. A mixture is the physical combination of two or more substances in which the identities are retained and are mixed in the form of solutions, suspensions and colloids.

MIXTURES? together. Four to be specific, called SOLUTIONS, SUSPENSIONS, COLLOIDS and EMULSIONS.

There are two types of mixtures: heterogeneous and homogeneous. Heterogeneous mixtures have visually distinguishable components, while homogeneous mixtures appear uniform throughout. The most common type of homogenous mixture is a solution, which can be a solid, liquid, or gas.

Mixtures can be classified on the basis of particle size into three different types: solutions, suspensions, and colloids. The components of a mixture retain their own physical properties.

list 3 properties of mixtures

• The composition of a mixture is not fixed.
• Constituents of a mixture can be separated by physical processes such as evaporation, boiling etc.
• No chemical process is involved in the formation of a mixture.
• The properties of the components of a mixture are retained.

Mixtures and compounds Hydrogen and oxygen are both gases. Together, as a mixture, hydrogen and oxygen can react and form water. Water is a compound of hydrogen and oxygen. The hydrogen and oxygen have joined together to form the new substance water.

Coca cola is a homogeneous mixture because the syrup and water are mixed evenly throughout the solution. Also you cant see the basic ingredients of a homogeneous mixture like coca cola, but heterogeneous means that you are able to see the basic ingredients for example a salad, so therefore coca cola is homogeneous.

A Tea is a solution of compounds in water, so it is not chemically pure. It is usually separated from tea leaves by filtration. B Because the composition of the solution is uniform throughout, it is a homogeneous mixture.

Salt mixtures can be either a mixture of different salts or solutions of them. Different types of salt mixtures can be defined, e.g., a solution of one cation and one anion is a binary solution, a solution of two cations and one anion or one cation and two anions forms a ternary solution, etc.

Vinegar is an example of a homogeneous mixture, and not a pure substance since water, its solute, is dissolved in the solvent, being acetic acid.

Glucose is a homogeneous mixture.

Normal blood glucose levels for adults, without diabetes, is 90 to 110 mg/dL. Learn the symptoms of high and low blood sugar here….Normal blood sugar levels for adolescents.

Coffee is a solution, not a compound or mixture, as it includes a solute that dissolves into a solvent. Coffee can also be considered a mixture since it involves two mixed substances, but this is too vague.

Answer. Answer: Glucose, also called dextrose, one of a group of carbohydrates known as simple sugars. Glucose is a polyprotic acid with 5 OH groups.

C6H12O6, which is glucose, is a compound and therefore a pure substance. Elements and compounds are pure substances.

Blood sugar, or glucose, is the main sugar found in blood. The body gets glucose from the food we eat. This sugar is an important source of energy and provides nutrients to the body’s organs, muscles and nervous system.

Where does sugar enter the blood? How can you tell where sugar enters the blood? Sugar level increases when blood goes through the intestines.

Carbohydrate: Includes bread, rice, pasta, potatoes, vegetables, fruit, sugar, yogurt, and milk. Our bodies change 100 percent of the carbohydrate we eat into glucose. This affects our blood sugar levels quickly, within an hour or two after eating. Protein: Includes fish, meat, cheese, and peanut butter.

When your blood sugar level gets too high — known as hyperglycemia or high blood glucose — the quickest way to reduce it is to take fast-acting insulin. Exercising is another fast, effective way to lower blood sugar….Eat a consistent diet
