How many compounds are present in the reactant side of the chemical equation 4Fe plus 3O2 arrow 2Fe2O3?
There are two compounds present on the reactant side of the chemical equation: iron (Fe) and oxygen (O2).
What is the chemical equation for the combustion of a nonmetal?
The combustion of a nonmetal, such as sulfur, involves the reaction of the nonmetal with oxygen to form its oxide. For example, the combustion of sulfur can be represented by the chemical equation: S + O2 → SO2.
Can a compound be separated into there component elements?
Yes, compounds can be broken down into their component elements through various chemical reactions. For example, water (H2O) can be separated into hydrogen (H2) and oxygen (O2) through the process of electrolysis.
This chemical equation is an example of which kind of a reaction?
single replacement
What is an example of stoichiometry?
An example of stoichiometry is determining the amount of product that can be produced in a chemical reaction. For instance, if you have the balanced chemical equation 2H2 + O2 -> 2H2O, and you know you have 4 moles of H2 and 2 moles of O2, you can use stoichiometry to calculate that you can produce 4 moles of H2O.
Which of these are chemical compounds O2 H2O CO2 N2?
H2O (water), CO2 (carbon dioxide) and N2 (nitrogen) are chemical compounds. O2 (oxygen) is a diatomic molecule, not a compound.
Where are the subscripts found in a chemical equation?
These subscripts are down the chemical symbol and at right. Example: O2
Which of the following is an example of an organic compound C6H12O6 NO2 H2O O2?
Organic chemistry is the study of carbon containing compounds. Inorganic chemistry is the study of all other compounds , that do not contain carbon. However, there are a number of 'cross-over' points, where inporganic chemical can be involved in organic chemistry. It follows that C6H12O6 is organic NO2 , H2O and O2 are inorganic. However, these three molecules can be involved in organic chemical reactions.
Is it correct to say that chemical changes are not reverisble but phycial changes are?
No, chemical reactions can be reversed. For example: 2H2O -> 2H2 + O2 can change back, 2H2 + O2 -> 2H2O

What is the product in this chemical formula n o2 no2?
The chemical formula "n o2 no2" seems to have a small formatting issue, but it likely refers to nitrogen (N) and oxygen (O) compounds. The products indicated by this formula could include nitrogen dioxide (NO2), which is formed when nitrogen reacts with oxygen. If the context involves a reaction, such as the combustion of nitrogen in oxygen, the primary product would be nitrogen dioxide.
What is chemical equeation?
Chemical equations show what happens when a chemical change occurs. For example, in the combustion of Hydrogen(H2), water(H2O) is formed. The chemical equation for this reaction is: 2H2 + O2 -----> 2H2O This chemical equation shows that when H2 reacts with O2 , H2O is formed.
Why compounds are molecules?
All compounds are made up of molecules. For example, salt, a compound, is composed of molecules (NaCl). By please do remember that molecules are not only limited to compounds. Meaning, there are also molecules that are not classified as compounds. The definition of a compound is a substance that is made up of two or more elements. A molecule is composed of two or more ATOMS connected by chemical forces. An example is oxygen air (O2). Oxygen air is a diatomic MOLECULE but it is NOT a COMPOUND.
Describe chemical combustion using an example?
Example: methane burning CH4 + 2 O2 → CO2 + 2 H2O
Can a compound be separated into there component elements?
Yes, compounds can be broken down into their component elements through various chemical reactions. For example, water (H2O) can be separated into hydrogen (H2) and oxygen (O2) through the process of electrolysis.
