How can you determine which chemical in a chemical equation is an acid and which one is a base, using the below-mentioned examples? Explain how to identify acids and bases in chemical reactions. a) SO2 + CaO gives CaSO3 b) Al(OH)3 + OH^- gives Al(OH)4^-. ...
Define each type of chemical reaction. In a synthesis reaction, two or more chemical substances combine to form a new compound, so the formula looks like A + B = AB. Decomposition is like the opposite of synthesis -- a compound breaks down into two or more components. Combustion reactions ...
Toxicologist:Toxicologists use analytical and scientific techniques to identify toxins such as chemicals, biological substances, and radiation to assess the potential risks and harmful effects present in them. What is the workplace/work environment of Biochemist like? Biochemists work indoors in fully ...
Explain how to identify acids and bases in chemical reactions. a) SO2 + CaO gives CaSO3 b) Al(OH)3 + OH^- gives Al(OH)4^-. What is the difference between a monoprotic acid and a diprotic acid? Give an example of each. What is hard and soft acids and bases concept? ...
Identify the starting material: Acetoacetic ester (ethyl acetoacetate) is the key starting material for this synthesis. Perform alkylation: Deprotonate the acetoacetic ester using a strong base like sodium ethoxide to form an enolate ion, then react it with an ...
350 ml of a 0.02 molar solution of NaOH is added to 500 ml of a 0.03 molar solution of HCl. Calculate the pH for the final solution. Step 1:Identify the acid and base in the solution. Acid-HCL, Base-NaOH Step 2:Convert both the acid and base into moles and subtract the...
CRed, colourless and blue DRed, violet and blueSubmit You have been provided with three test tubes. One of them contains distilled water and the other two contain an acidic solution and a basic solution, respectively. If you are given only red litmus solution, how will you identify the cont...
How do you identify effervescence? In the laboratory, a common example of effervescence is seen ifhydrochloric acid is added to a block of limestone. If a few pieces of marble or an antacid tablet are put in hydrochloric acid in a test tube fitted with a bung, effervescence of carbon dioxi...
First of all I would like to say that we had quite a strong field of applications this year, so it was not so easy to identify a winner among them, and this as usual takes quite a while of discussions and checking out and so on. And in the end, we chose the winner as Maurice ...
Be aware of possible star activity under non-optimal reaction conditions (See the Reference Table Relative Activity of Restriction Enzymes in Promega 10X Buffers or use the Restriction Enzymes interactive search tool to identify compatible buffers). Choose an isoschizomer or neoschizomer with more ...
