What is the color of oxygen and why? What is a substance's SLOW reaction to oxygen? What are the physical and chemical properties of bromine? a) Why is water an important solvent? b) What properties of water make it so important?
What is the density of chlorine gas?Chlorine GasChlorine is a chemical element with atomic number 17. It is the second largest of the halogens. It is very toxic as a gas and was used as a weapon in World War I. It has a yellow-green color....
It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, structure, behaviour, and changes that occur when they interact with other things. The quantum mechanical approach is currently used...
"Schoenbein" paper, that is coated with potassium iodide (KI) and corn starch. Water is added to the strips immediately before use. Schoenbein test strips turn blue-purple in the presence of ozone, the color being a rough indicator of ozone concentration. Iodine gas (I2) is generated when...
Titrant is added until the reaction is complete. To be suitable for determination, the end of the titration reaction must be easily observable when monitored (indicated) by appropriate techniques, e.g., potentiometry (potential measurement with a sensor) or through a color change. The measurement...
Halogens are a group of highly reactive, nonmetal elements which include fluorine (F), chlorine (Cl), bromine (Br) and iodine (I). Due to their reactivity, these elements are found only in nature as compounds and ions. Additionally, these elements form highly toxic and corrosive gasses when...
To do so, sodium hydroxide and bromine are added to an ice-water solution of succinimide. The NBS product precipitates and can be collected by filtration. Crude NBS gives better yield in the Wohl-Ziegler reaction. In other cases, impure NBS (slightly yellow in color) may give unreliable ...
bromine, and hydrogen (the halogen family in the periodic table of the elements). These are often described by the general termhalocarbons.The compounds include chlorofluorocarbons (CFCs which are used as refrigerants, foam-blowing agents, electronics cleaners, and industrial solvents) as well as hal...
Chlorine is a chemical element with the symbol Cl and atomic number 17. The second-lightest of the halogens, it appears between fluorine and bromine in the periodic table and its properties are mostly intermediate between them. Bleach To remove the color from, as by means of chemical agents ...
Yes, bromine is an example of a nonmetal that is liquid at room temperature. 8 Do nonmetals have any metallic properties? Nonmetals do not exhibit metallic properties such as luster, malleability, or good electrical conductivity. 7 What happens to metals in an ionic reaction? In ionic reaction...
