In a balanced chemical equation we have
WebHow can the coefficients in a chemical equation be interpreted? A balanced chemical equation can tell us the number of reactant and product particles (ions, atoms, molecules or formula units) that are necessary to conserve mass during a chemical reaction. Typically when we balance the chemical equation we think in terms of individual particles. WebExplanation : We have the unbalanced equation. C 4H 10(g)+O 2(g)→CO 2(g)+H 2O(g) This is the combustion of butane C 4H 10. Let's first balance the carbons. There are four on the LHS, but only one on the RHS, so we multiply CO 2 by 4 to get. Final step is to balance the oxygens. There are two on the left hand side, but thirteen on the right ...
