Question

3. Classify each of the following as a non-electrolyte, weak electrolyte or strong electrolyte Substance Classification nickel(II) nitrate Ni(NO3)2 nodulo sucrose C12H22011 bronsvort oldulo no no nom od ysm 910 methyl alcohol CH3OH acetic acid CH3COOH be thorouble loos potassium bromide KBr 4. Write the chemical equations for solution formation in water for each of the following substances. Include the appropriate phase labels and arrows, or in your equations. Substance Equation A magnesium bromide MgBra(s) B fructose C6H12O6(s) C isopropyl alcohol C3H,OH() D lactic acid C3H6O3(s) Would you expect to observe a higher concentration of dissolved oxygen in a lake close to sea level or in a mountain lake? Assume the water temperature is the same. Provide an explanation and reference Henry's law and how altitude affects the atmospheric pressure.

D. OH Lactic acide C3 MG 03 (5) #120 - hc-ch+600 69 + H₂ Offago In higher attitude partial Onuggen gas decreases so, fraction of Oxygen gas in (Lake here) also decreases pressure of the more solution 1 = Up According to Henry's law amount of dissomed gas in a liquid is proportional to its partial pressure above the liquid, In comes altitude , pressure is highes than higher altitude. so, the amount of dissowed oxygen gas is more in comer altitude them in higher actitude.
