- Write TRUE if the underlined word/phrase makes the statement correct. Otherwise, write the correct WORD/PHRASE that will make the statement true. If there are two bold words/phrases in a number, write your answer for EACH of the bold words/phrases 1. 6-hydroxy-1-naphthoic acid is soluble in 5% NaOH and soluble in 5% NaHCO3. 2. The addition of excess charcoal would decrease the % recovery in the purification by recrystallization. 3. If the target compound is contaminated with impurity, the melting point will be higher than the theoretical value and the melting range is large.In parts 1 and 2 draw the two organic products of this reaction, showing any nonzero formal charges. Then, in part 3 answer the question regarding purification of the reaction mixture. 1. Draw the product with the higher molecular weight here 2. Draw the product with the lower molecular weight here 3. Which method would be the simplest and most effective means to best separate the two products?

Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a) it is able to prevent 4-tert-butylphenol from evaporating b) it is able to prevent 4-tert-butylphenol from subliming c) it is able to prevent copper(II) bromide from evaporating d) an air condenser can prevent evaporation of acetonitrile because it has a boiling point of 81-82 °C and will not be boiling at 60 °C e) an air condenser can prevent water from entering the reaction flaskThis topic is about organic andinorganic compound. This is for our laboratory, don't have access to b and c. I am hoping that you did the same experiment before. Please guide me. 1. What will happen if:(a.) You heat a pinch of table salt in a clean, dry test tube for two minutes then cooled down.(b.) You Heat a pinch of cane sugar in a dry pyrex test tube.(c.) You Heat a benzoic acid in a dry pyrex test tube. 2. Give a general statement as to the difference in stability towards heat of organic and inorganic compounds. Thank you so much in advance, ask me some questions if something is missing.
