What else can I help you with?
Are table sugar and salt pure substance?
Yes. Both are compounds with definite compositions. Table sugar is also called sucrose, and its chemical formula is C12H22O11. Table salt is also called sodium chloride, and its chemical formula is NaCl.
What are the mineral chemical compositions of the rock samples collected from the excavation site?
The mineral chemical compositions of the rock samples collected from the excavation site include elements such as silicon, oxygen, aluminum, iron, calcium, sodium, and potassium.
Does salt have definite chemical composition?
Yes. Pure table salt is Sodium chloride ( NaCl ) .
Is sodium hydroxide and bleach the same thing?
No, sodium hydroxide and bleach are not the same thing. Sodium hydroxide is a strong base commonly known as lye, while bleach is a chemical solution that typically contains sodium hypochlorite as the active ingredient. They have different chemical compositions and properties.
Why are solid?
solids have definite volume and shape. They are solids due to many factors including chemical compositions, the temperature in which they can stay solid, etc.

Is sodium chloride a substance or a mixture?
Sodium chloride, NaCl, is a compound, which is a pure substance. It is a compound because sodium ions and chloride ions chemically bond to each other to form the ionic compound NaCl.
Is sodium hypochloride the same as muriatic acid?
No, sodium hypochlorite is a chemical compound often used for disinfection, while muriatic acid is a different compound commonly used for cleaning and etching. Both substances have different chemical compositions and properties.
What is a defintite chemical composition?
In mineralogy, definite chemical composition refers to a characteristic that a substance must possess to meet the definition of a mineral. It is the narrow parameter of chemical compositions that a substance must have to be described as a particular mineral separate from other minerals.
Why does sodium metal and sodium chloride behave different?
Sodium metal is a pure element, while sodium chloride is a compound composed of sodium and chlorine ions. Therefore, their chemical properties and behaviors differ due to the difference in their compositions. Sodium metal is a highly reactive metal, while sodium chloride is a stable compound commonly used as table salt.
What are fixed compositions or uniformed compositions?
Fixed or uniform compositions are characteristic of chemical compounds.
What characteristic of minerals is not a characteristic of mineraloids?
One key characteristic that is not a characteristic of mineraloids is definite chemical composition. While minerals have a specific chemical composition, mineraloids lack a precise chemical formula or have variable compositions.
