write the chemical equation and balanced |
| Answer» 1. A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formulae, wherein the reactant entities are given on the left-hand side and the product entities on the right-hand side. ... The first chemical equation was diagrammed by Jean Beguin in 1615.2. A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge are the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction. | |
| 43563. |
Why do we need to balace a chemical equation? |
|
Answer» The chemical equation needs to be balanced so that it follows the law of conservation of mass. A balanced chemical equation occurs when the number of the different atoms of elements in the reactants side is equal to that of the products side. Balancing chemical equations is a process of trial and error.\xa0 We need to balance chemical recation to equal the reactants and products To satisfy the law of conservation of mass...we need to balance d equation |

Explain briefly what is light reaction and dark reaction in photosynthetic plants. |
| Answer» 1. Light reactions :............It occurs in the grana where photon are absorbed so as to excite electrons of chlorophyll to a higher energy level. These activated elctrons are harnessed to form ATP from the ADP and reduce NADP to NADPH. Wayer ia also spotted here and oxygen is released...............2. Dark reactions :............Calvin cycle occurring in chlorophyll here carbon combine with 5-carbon sugar called ribulose biphospahte. This unstable compound breaks down into 3-carbon compound. This then forms glucose............... | |
