Problem- Ionic compounds have much higher melting and boiling points than covalent compounds, even though covalent bonds are just as strong as ionic bonds. Explain why (please include a thorough explanation).
Please answer only if you are 100% confident
Air bags are activated when a severe impact causes a steel ball to compress a spring and electrically ignite a detonator cap. This causes sodium azide (NaN3) to decompose explosively according to the following reaction.
Explain what the final concentration of a NaOH solution is when 67mL of .75M NaPH is poured into a volumetric flask and diluted to 5.0L with water
Calculate the theoretical amount of NH4NO3 that would be required to change the temperature of 50 ml of water from room temperature 20 C to 5 C.
A solution of I2 was standardized with ascorbic acid. Using a .1000 g sample of pure ascorbic acid, 25.32 mL of I2 were required to reach the starch end point. A. What is the molarity of the iodine solution? B. What is the titer of the iodine solu..
The mass percentage of iodine in the compound was determined by converting the iodine in a 0.850 g sample of the compound into 2.31 g of lead(II) iodide. What is the empirical formula of the compound? Could the compound also contain oxygen?
Problem- Part 1) Why reaction of 2-butanone with LiAlH4 results in the formation of a racemic mixture rather than a single enantiomeric product?
Chlorine(Cl2) is used as a germicide to kill microbes in swimming pools. if the product is Cl^-,was the elemental chlorine oxidized or reduced
The dehydration of trans-2-methylcyclopentanol with H2SO4 will give what major product? a) cyclopentene b) 1-methylcyclopentene c) 2-methylcyclopentene d) 3-methylcyclopentene
