What does the 2 mean in 2CO?
Answer: According to chemistry CO stands for carbon monoxide. 2CO represents 2 molecules of carbon monoxide. Carbon monoxide contains one carbon atom and one oxygen atom.
What is 2CO2?
2CO2. It’s read as 2 Carbon dioxide molecules. CO2 contains one atom of the element Carbon and 2 atoms of the element Oxygen. A number that comes before a compound or molecule e.g 2 in this case is indicating that there are 2 carbon dioxide molecules.
What does the big 2 in 2nahco3 mean?
Thus, the symbol “2 NaHCO3” indicates two units of sodium bicarbonate, which contain 2 Na atoms, 2 H atoms, 2 C atoms, and 6 O atoms (2 X 3= 6, the coefficient times the subscript for O).
What does the little 2 mean in Co₂?
The subscript 2 represents that two atoms of oxygen combines with 1 atom of carbon to give CO₂.

What does the Big 3 in 3 H2O mean?
This means there are two H’s (hydrogen atoms) in each molecule. • The coefficient 3 shows that there are three of the H2O molecules. We could draw each molecule to help show us how many atoms are present.
What does the C stand for in carbon dioxide?
CO2
Carbon (often abbreviated with the chemical symbol C) is the sixth most abundant element on Earth. Carbon dioxide or CO2 is the chemical compound of two oxygen atoms and one carbon atom, at room temperature it is gaseous and is a vital gas for life in the atmosphere since it plays a major role in photosynthesis.

Any molecule you have the atoms for you can build, with the exclusion of cyclic molecules and those that result in atoms overlapping as you build them. For the third tab, which has the most atoms available, you can build ~ 9,000 molecules!
How many atoms does Al OH 3 have?
There are seven atoms in one formula unit of Al(OH)₃.
Why CO2 is not used as an inert gas?
Nitrogen gas and carbon dioxide are referred to as inert gases because of their very low reactivity. These gases are not inert in the same way as the noble gases, which exist in their elemental form. They do behave similarly to the noble gases, however.
