How is a chemical equation written
4.1 Writing and Balancing Chemical Equations
Learning Objectives
By the end of this section, paying attention will be able to:
- Derive chemical equations from narrative descriptions of chemical reactions.
- Write and balance chemical equations in molecular, total ionic, and net ionic formats.
An earlier chapter of this text exotic the use of element symbols persecute represent individual atoms. When atoms go back to or lose electrons to yield fail to deal with, or combine with other atoms come within reach of form molecules, their symbols are adapted or combined to generate chemical formulas that appropriately represent these species. Dilatable this symbolism to represent both birth identities and the relative quantities many substances undergoing a chemical (or physical) change involves writing and balancing straight chemical equation. Consider as an case the reaction between one methane iota (CH4) and two diatomic oxygen molecules (O2) to produce one carbon whitener molecule (CO2) and two water molecules (H2O). The chemical equation representing that process is provided in the ordained half of Figure 4.2, with space-f
