What is ScBr3?
ScBr3 is the chemical formula for scandium tribromide. It is a compound composed of scandium and bromine atoms, where scandium has a +3 oxidation state. ScBr3 is a yellowish solid at room temperature and is commonly used as a catalyst in organic synthesis reactions.
How many moles of ions are present in aqueous solutions prepared by dissolving 10.00g of the f scandium III bromide in water to make a 1.25 L solution?
First figure out the formula of Scandium(III) Bromide: its ScBr3. Next ignore the 1.25 L solution part -- it's just extra information. Use the 10.00g to convert it to moles. To do so first figure out the molar mass of ScBr3: its 285g/mol. Now you do: 10.00g x 1 mol/285g = .0350877193... mol. Next round it to 3 significant figures: .0351. Now you find out the number of ions in the formula and use it as a conversion factor (instead of Avagrado's number, 6.02 x 1023): it has 4 ions (Scandium = 1; Bromide = 3). Finally you do: .0351 mol x 4 mol ions/1 mol = .1404 mol ions. This is your answer! By Geovonni Bell ;-)
What are the five major branches of chemistry?
there are five branches: inorganic, organic, analytical, physical, and biochemistry. they could be further broken down into sub-branches such as organometallic chemistry, physical organic chemistry, electroanalytical chemistry, and so on and so forth.
How do you spell chemistry?
Chemistry
Use the word chemistry in a sentence?
chemistry is very important. chemistry is different from bio chemistry .
What are the sub-branches under chemistry?
there are many branches of chemistry. Organic chemistry is the study of chemistry of life. Inorganic chemistry is the study of inorganic compounds. Analytical chemistry is the study of the chemistry of matter. Physical chemistry is the study of chemistry applying physics. Biochemistry Radiochemistry Photochemistry Cosmochemistry Hydrochemistry Electrochemistry Clinical chemistry Neurochemistry Forensic chemistry Macromolecular chemistry etc.
Discuse the 5 major branche of chemistry?
Analytical Chemistry Biochemistry Inorganic Chemistry Organic Chemistry Physical Chemistry
Is inorganic and general chemistry the same?
Inorganic chemistry is a branch of chemistry that focuses on the properties and behavior of inorganic compounds, while general chemistry covers all basic principles and concepts of chemistry, including inorganic chemistry. General chemistry is a broader discipline that encompasses various branches of chemistry, including inorganic chemistry.
How many branche of chemistry?
Examples: biochemistry, inorganic chemistry, organic chemistry, photochemistry, radiochemistry, agrochemistry, cosmochemistry, macromolecular chemistry, analytical chemistry, electrochemistry, colloid chemistry, clinical chemistry, immunochemistry etc.
Which chemistry focuses on composition of matter?
Analytical Chemistry is the study of composition of matter. It is the branch of chemistry that deals with properties of materials and analysis of them with the help of tools.
How does chemistry affect cosmetics?
Chemistry does more with physics than chemistry does with chemistry. in English, it just does........................... ;)
