(a) Write reactions to show how glucose separately reacts with (i) NH(2)OH (ii) HNO(3) (iii) ammoniacal AgNO(3) (b) What do you understand by (i) de
What is an enthalpy change in physical chemistry? How to calculate enthalpy change Why are decomposition reactions endothermic? How is an exothermic reaction identified? What conditions must be met by a thermochemical equation so that its standard enthalpy change can be given the ...
Balance the redox reaction in solution (acidic) H+ + Al --> H2 + Al3+ Balance the redox reaction by the ion-electron half-reaction method: Cr_2 O_7^{2-} + U^{4+} to UO_2^{2+} Balance the following redox reactions: a. ClO3� + SO2...
say AB and CD. The products of the reaction interchange components to produce AD and BC. That is, AB + CD → AD + BC. At the student level, double displacement reactions can be demonstrated in a variety of interesting, instructive ways. ...
as you know by now the typical steps to balancing a redox reaction don't work well. (1) identify the oxidiation states of every atom (2) determine which atoms are oxidized and which are reduced (3) write half reactions (including e's) ...
an ion with a positive charge, or an anion, an ion with a negative charge. Chemists use a very simple notation to represent ions in chemical reactions. Although you may need to remember some common polyatomic ions, for the most part, you can figure out the symbols for ions just using th...
Ethyl acetoacetate (acetoacetic ester) is easily converted to its enolate anion bysodium ethoxide, and, like other anions, this salt will carry out displacement reactions with suitable halides. Hydrolysis of the resultant ester and decarboxylation by heating gives a ketone. ...
1. You need to know that 1 acre = 0.404686 hectares and/or 1 hectare = 2.471 acres depending on the conversion 2. Always write down the units of your eventual answer (hectares in this case) to the right side of the equation like so: This helps you 'see' that you are working you...
Here, we can only bind noble gases in laboratories, but in outer space, those chemical reactions happen naturally, and these so-called "impossible elements" may provide vital answers to the mystery of the universe's formation. How noble gases work Thom Leach / Science Photo Library/Getty ...
How can one determine if an ordered pair is a solution to an equation? How do you write a compound which contains calcium (Ca) and the polyatomic ion chlorate (ClO3)? When doing single replacement reactions, how do we know what the element being replaced will be?
