Chemical reactions- The transformation of chemical substance into a new chemical substance by making and breaking of bonds between different atoms is known as Chemical Reaction. Signs of a chemical reaction- These factors denote that a chemical reaction has taken place- change of state of substance, change of color of substance, evolution of heat, absorption of heat, evolution of gas and evolution of light. Chemical Equation: The representation of chemical reaction by means of symbols of substances in the form of formulae is called chemical equation. Balanced Chemical Equation: A balanced chemical equation has number atoms of each element equal on both left and right sides of the reaction. To obey this law, the total mass of elements present in reactants must be equal to the total mass of elements present in products. Combination- When two elements or one element and one compound or two compounds combines to give one single product.


and chemical changes of matter in our previous classes. equation is a skeletal chemical equation for a reaction. In each test tube, take about 10 mL.

Хотя Сьюзан практически не покидала шифровалку в последние три года, она не переставала восхищаться этим сооружением. Главное помещение представляло собой громадную округлую камеру высотой в пять этажей. Ее прозрачный куполообразный потолок в центральной части поднимался на 120 футов. Купол из плексигласа имел ячеистую структуру - защитную паутину, способную выдержать взрыв силой в две мегатонны. Солнечные лучи, проходя сквозь этот экран, покрывали стены нежным кружевным узором. Крошечные частички пыли, пленницы мощной системы деионизации купола, простодушно устремлялись вверх широкой спиралью. Наклонные стены помещения, образуя вверху широкую арку, на уровне глаз были практически вертикальными.
