Is carbon an element or a compound and why?
Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms, and because the carbon atom is just the right, small size to fit in comfortably as parts of very large molecules. … They can even join “head-to-tail” to make rings of carbon atoms.
Is carbon dioxide a pure substance or a compound?
Yes, carbon dioxide is a pure substance. It’s a compound that consists only of carbon dioxide molecules and it has consistent composition throughout the sampling area. A pure substance is a matter that consists of 1 type of element or 1 type of substance. If you take a sample of a pure substance, it should have constant composition no matter on which area it is taken from.

Is carbon dioxide a heterogeneous, homogeneous, or a mixture?
Carbon dioxide is not a heterogenous or a homogeneous mixture. It is a compound, where the different elements are chemically bonded together. It could be considered homogeneous, as it is uniform in composition throughout, but it isn't properly called a mixture, but a compound.
Did carbon dioxide is a mixture?
Carbon dioxide is a mixture of carbon and oxygen.
Why carbon dioxide is an element?
Solution: Carbon is an element and Carbon dioxide constitutes of carbon and oxygen which are both independent elements combined together in a fixed ratio to form carbon dioxide.
Is carbon dioxide an element or a compound give reasons?
Carbon dioxide is a compoundbecause: i) It has different chemical and physical properties from the carbon and oxygen the makes it. ii) You can only separate carbon from oxygen incarbon dioxide using a chemical reaction. iv) Carbon and oxygen that make up the carbon dioxideare chemically bonded to form this compound.
Is carbon dioxide an element True or false?
Explanation: CO2 is a compound( made up of two or more elements) not an element. It contains two elements carbon and oxygen.
What is pure substance?
A pure substance is one that contains only one kind of matter. A pure substance could be a single element (like Gold), or it could be a compound (like water). Every instance of this substance must be exactly the same. It acts the same, and reacts the same. Because carbon dioxide will also have the same composition no matter where ...
What is the gas that makes fog?
In fact, it is carbon dioxide that has been frozen solid. The fog you see is a mixture of carbon dioxide gas and cold humid air, which is formed as the dry ice melts.
Is CO2 a mixture or a substance?
As we mentioned in the intro, the elements that make up carbon dioxide (carbon and oxygen) are chemically bonded. They don’t come apart easily at all. A mixture is a material where the substances in the mixture are not chemically bonded to each other. Thus CO2 doesn’t qualify.
Is carbon dioxide a mixture or a compound?
No, carbon dioxide is not a mixture. Carbon dioxide is composed of carbon chemically bonded to oxygen. Because of this chemical bond that is difficult to break, carbon dioxide is not considered a mixture. Instead, carbon dioxide is considered to be a compound. Feeling confused?
Is CO2 an organic compound?
In most cases, to be considered organic, the material must contain some carbon to hydrogen bonds. CO2 has no hydrogen bonds to its carbon. In general, most carbon compounds (like carbides, carbonates, and cyanides) are considered inorganic.
Is CO2 toxic to humans?
To be considered a toxic to humans, it is a substance that causes serious physical harm or death if it is ingested, breathed, or otherwise taken into the body. CO2 can definitely cause you harm if you breath it, especially if you breath a lot of it and for an extended period of time. Now, here’s the thing.
Is CO2 homogeneous or homogeneous?
But with pure CO2, you won’t be getting any other elements, compounds or mixtures either. This is why we say that it is homogeneous.
What Is Carbon Monoxide?
Carbon monoxide (CO) is an odorless, colorless, toxic substance that is produced when a combustion reaction isn’t complete.
Is Carbon Monoxide an Element?
No, carbon monoxide is not an element. Carbon monoxide consists of TWO different elements i.e. Carbon and Oxygen.
Is Carbon Monoxide A Compound or Mixture?
Carbon monoxide (CO) is a compound that consists of Carbon atom and Oxygen atom that bond chemically. The ratio of Carbon Monoxide is always the same (1 Carbon and 1 Oxygen). Thus, carbon monoxide is classified as a compound, not a mixture.
