1. What are the differences between lonic and covalent bonds?
zaharov [31]

Answer: Ionic bonds result from transfer of electrons, whereas covalent bonds are formed by sharing. ... Ionic bonds are electrostatic in nature, resulting from that attraction of positive and negative ions that result from the electron transfer process; charge separation between covalently bonded atoms is less extreme.

A mixture of two compounds, A and B, was separated by extraction. After the compounds were dried, their masses were found to be:
Arlecino [84]

Answer:

The percent recovery from re crystallization for both compounds A and B is 69.745 and 81.44 % respectively.

Explanation:

Mass of compound A in a mixture  = 119 mg

Mass of compound A after re-crystallization = 83 mg

Percent recovery from re-crystallization :

\frac{\text{Mass after re-crystallization}}{\text{Mass before re-crystallization}}\times 100

Percent recovery of compound A:

\frac{83 mg}{119 mg}\times 100=69.74\%

Mass of compound B in a mixture  = 97 mg

Mass of compound B after re-crystallization = 79 mg

Percent recovery of compound B:

\frac{79 mg}{97 mg}\times 100=81.44\%

Which of the following aqueous solutions has the highest boiling point?A. 1.25 M Ca(NO3)2B. 1.25 M KNO3C. 1.25 M CH3OHD. 2.50 M
Drupady [299]

Answer:

Ca(NO3)2 has the highest boiling point ( option A)

Explanation:

Step 1: Data given

A. 1.25 M Ca(NO3)2

B. 1.25 M KNO3

C. 1.25 M CH3OH

D. 2.50 M C6H12O6

Step 2: Calculate highest boiling point

The boiling point depends on the van't Hoff factor

This shows the particles produced when the substance is dissolved. For non-electrolytes dissolved in water, the van' t Hoff factor is 1.

Ca(NO3)2 → Ca^2+ + 2NO3- → Van't Hoff factor = 3

KNO3 → K+ + NO3- → Van't Hoff factor = 2

CH3OH is a non-elektrolyte → Van't Hoff factor = 1

C6H12O6 is a non-elektrolyte → Van't Hoff factor = 1

Ca(NO3)2 has the highest boiling point
