Silicon dioxide is a substance (chemical compound) consisting of one silicon atom and two oxygen atoms.
No, a quark is and immeasurable thing that makes up everything (approximately) in our world. It is a sub-atomic particle, not a mixture which is totally different.
No. Sulfur dioxide is a compound, which makes it a pure substance, not a mixture.
is silicon a mixture? Silicon is a pure substance because it is an element.
Silicon is an element, not a mixture. It is a solid metalloid that is commonly found in nature in its pure form.
It can be considered a mixture since sandstione contains several different minerals, although it is mostly the minerals quartz (silicon dioxide) and feldspar (related silicates).
Quartz is a compound. There are many different types of quartz, each containing different materials.
No, a quark is and immeasurable thing that makes up everything (approximately) in our world. It is a sub-atomic particle, not a mixture which is totally different.
Silicone is a pure substance made up of silicon, oxygen, carbon, and hydrogen atoms. It is not a mixture because these atoms are combined in a specific and consistent ratio.
No, carbon dioxide is not a mixture. It is a pure substance.
Carbon Dioxide is not a mixture. It is a chemical compound composed of two oxygen atoms and one carbon atom.
Whiteout is not a pure substance. It is a mixture of various chemicals, such as titanium dioxide, solvents, and binders.
Neither. Carbon dioxide is a pure substance, not a mixture.
Neither. Carbon dioxide is a pure substance, not a mixture.
CO2 is a pure substance made of two elements, Carbon and Oxygen.
No. Sulfur dioxide is a compound, which makes it a pure substance, not a mixture.
Silicon dioxide is not a reactive solution and therefore pH does not apply to it.
a substance because glass needs a chemical reaction
