Sodium bromide (NaBr) is used to treat seizures in dogs and cats while tetrabromomethane (CBr4) is used as a solvent for greases, waxes and oils.(a) Draw the'dot and cross' diagram to show the bonding in tetrabromomethane. [2]Show only the valence electrons.(b) Sodium bromide has a ...
17Aqueous chlorine is added to agueous sodium bromide and the mixture is shaken with an equal volume of trichloromethane.Which observation will be made?D A The solution in the test-tube turns colourless. B The solution in the test-tube turns orange. C A colourless layer forms on top of ...
Why is it not advisable to react an acid with sodium chloride directly? Why are anions always larger than the atoms from which they are formed? Why is NaCl described as a strong electrolyte? Does solid NaCl conduct electricity? Explain why or why not. Why does s...
Owing to a limited extent of the reaction in water, the undissociated form of a weak acid is a. the only form found in the solution. b. more concentrated than the dissociated form. c. absent from the solution. You added 3ml stock solution of 0.05mg/ml of dye and 7ml of water, what...
A method of producing nanoclays comprising the steps of preparing a first intercalant alkali salt of a carboxylic acid, adding the first intercalant to a swelled clay at a temperature of at least 50° C. so that the metal ions on the clay surface forms a

(100 μL) of tissue homogenate and 10 μL of 4 µg mL−1glycyrrhetinic acid IS were mixed well in a miniature mortar. Then a predetermined amount of anhydrous sodium sulfate was added to absorb all the water in the mixture. The dried mixture was ground to a powder, which ...
We analyzed the MIF amino acid sequence across multiple species and identified a PIP box-like motif (Supplementary Fig. 4b). To determine whether MIF directly binds to PCNA through the PIP box-like motif, we mutated two conserved residues L47 and F49. We found that L47A, F49Y, or ...
This last suggestion has been observed with another lipid-soluble weak acid, the Cl- channel blocker NPPB, restricting its use to <100 μM [61]. In addition, DIOA has been shown to interfere with ATP recovery after metabolic insult and to release cytochrome c from isolated mitochondria at ...
