What is mass ratio in chemistry? Stoichiometry: Stoichiometry refers to the calculations made to find amount of reactants and products in a chemical reaction. Stoichiometry is based on the law of conservation of mass, where the total mass of reactants will have to produce an equal amount of...

有一种棕黑色的固体铁化合物A，与盐酸作用生成浅绿色溶液B，同时放出臭味气体C，将C通入CuSO4溶液生成棕黑色沉淀D，将Cl2通入B中得到黄色溶液E，向E中加入KSCN试液得血红色液体F，向F中加入NaF固体生成无色液体G。试指出A.B.C.D.E.F.G各位何物，并写出有关的反应方程式。
What is the hybridization of the bromine atom in BrF5? What is flash point in organic chemistry? Which compound has the lowest normal boiling point? What are the properties of bromine? Which compound has the highest boiling point? HF, HI, HBr, HCl, or F2?
What is the molar mass of PbI2? How can the number of moles of barium nitride be determined from its mass? How many grams of barium sulfate can be produced from 0.100 mole of barium chloride? What is molar mass in chemistry? How many grams of barium chloride are needed to make 100 gra...
Snow and ice in Earth's cryosphere greatly affects the overlaying atmosphere. Sunlit natural snowpack and ice surfaces may emit a wide range of trace gases, such as reactive nitrogen species, molecular halogens (Cl2, BrCl, Br2, etc), and volatile organic compounds. In particular, the ...
In the case of low bromoform initial mixing ratios, which are more representative of the mean distribution in the tropics, this Br2 production process is shown to be less important. These conclusions could nevertheless be revisited if the knowledge of chlorine and bromine chemistry in the cloud ...
Tags Chemistry Organic Organic chemistry In summary, the conversation discusses the formation of a saturated cyclohexane from a double bond and two bromine atoms. It is mentioned that platinum is a good hydrogenation catalyst and the bromine atoms detach from the ring, leaving room for hydrogen atom...
Bromine water is an orange solution of bromine. It becomes colourless when it is shaken with an alkene. Alkenes can decolourise bromine water, but alkanes
