It occurs when gases such as nitrogen (N₂) come out of solution in the blood. This can lead to symptoms including joint pain, shortness of breath, and paralysis. Severe cases may result in death. a What type of molecule (ionic, polar covalent, nonpolar covalent) is nitrogen gas? b The liquid medium of blood is water. What type of compound (ionic, polar covalent, nonpolar covalent) is water? c What happens when molecules such as nitrogen gas mix with water? How does this explain the problems we see with decompression sickness?

Question 4 is needed to answer question 5. I had provided the answers for question 4. I just struggled finding the answers for 5 and I was hoping someone would be able to explain/show the steps in writing. Thank you!

FINAL Experiment 1- January 2021_-789644623 - Saved Layout Review View Table A friend of yours went panning for gold last weekend and found a nugget that appears to be gold. With your newfound scientific prowess, you set out to determine if it is really gold. Your tests show that the nugget has a mass of 7.6 g. Immersing the nugget in water raised the volume from 7.22 mL to 8.06 mL. The density of gold is 19.32 g/cm3. What will you tell your friend? acer

A group of students performed a melting point experiment to study the physical properties of ionic and covalent solids. The data collected are shown in the table.  Solid Sample Melting Point (oC)  Time Elapsed (min) Table Sugar (sucrose) 186 18 Table Salt (sodium chloride) 500 (not observed) 30  Paraffin Wax 37 4  Vegetable Lard 50 >5 Using the information contained in the table, what is the BEST explanation for the results?A    The melting point of sodium chloride was not observed because ionic solids do not melt, whereas sugar, wax, and lard melted because they are softer than salt.B    The melting points of covalently bonded solids tend to be lower than ionic solids. The melting point of sucrose was greater than the wax or the lard because sucrose has stronger bonds than wax or lard.C    The melting point of sodium chloride was not observed because ionic solids are composed of positive and negative ions that do not melt; whereas, the…
