Well it depends........
Here are 3 possible answers.......
Cement chemist notation: C3S + H → C-S-H + CHStandard notation: Ca3SiO5 + H2O → (CaO)·(SiO2)·(H2O)(gel) + Ca(OH)2Balanced: 2Ca3SiO5 + 7H2O → 3(CaO)·2(SiO2)·4(H2O)(gel) + 3Ca(OH)2
The are the chemical combination of what is required
The chemical symbol for strontium is Sr. The chemical symbol for copper is Cu.
C is the chemical symbol for carbon.
There is no symbol for Al2O3 as it is a compound, chemical symbols are for elements
Methamphetamine is a compound and therefore has a chemical formula. Only elements have chemical symbols. Methamphetamine's formula is C10H15N.
A chemical compound is represented by a specific combination of chemical elements bonded together in a specific ratio. This combination is represented by a chemical formula that shows the type and number of atoms of each element in the compound.
Concrete is a mixture not a chemical compound.
The chemical symbol for strontium is Sr. The chemical symbol for copper is Cu.
Helium (He) is a chemical element, not a compound; the chemical symbol is He.
C is the chemical symbol for carbon.
Tea is not a chemical compound but a mixture and so it has nu chemical symbol.
The state symbol aq means it dissolves in water when it is written after a chemical compound in a chemical reaction.
The chemical symbol for the compound borax is Na2B4O7·10H2O.
There is no symbol for Al2O3 as it is a compound, chemical symbols are for elements
The chemical symbol of a molecule represents the individual elements present in the compound, while the chemical formula shows the ratio of each element in the compound. The formula is essentially a written expression of the molecule's composition and structure, making it equivalent to the symbol in chemical representation.
F is the chemical symbol of fluorine.
The symbol for nicotine (a compound) is C10H14N2.
The chemical symbol for chalk is CaCO3, which represents the compound calcium carbonate.
