A KBr pellet should be translucent. Explain why.
Explain why the baseline is not 100% T for the KBr pellet and the Nujol mull spectra of benzoic acid.
Explain why the baseline is not 100% T for the KBr pellet and the Nujol mull spectra of benzoic acid. Consider all components that could affect the transparency
Please explain Incorrect. Before working this problem, review Conceptual Example 14. A pellet gun is fired straight downward from the edge of a cliff that is 14.0 m above the ground. The pellet strikes the ground with a speed of 28.5 m/s. How far above the cliff edge would the pellet have gone had the gun been fired straight upward? Number [22.19 Units
KCl and KBr are both ionic solids. A mixture of KCl and KBr has a mass of 3.595 g. When this mixture is heated in the presence of excess Cl2, all of the KBr is converted to KCl. If the total mass of KCl present after this reaction is 3.129 g, what percentage (by mass) of the original mixture was KBr? (HINT: Be sure that you understand why the mass of the sample has decreased. It may help if you...
