- Please answer this question as fast as you can please and tahnk you. I will afterwards write an wonderful review on solving the question. Thank you. Why is it important for us to leave the water for 5 minutes and determine the water's temperature? The density of water will vary with temperature. You want the water to equilibrate to room temperature in order to maintain consistent results. You want to wait so that the dissolved solids in the water settle to the bottom of the flask. It is impossible to determine the density of water below 20 °C with plastic beakers and cylinders so you need to wait for the water to warm up. It's not that important, we just want to stretch out the time of the experiment.Deviations from ideal behavior occur at low concentrations True or FalseIf a deep-sea diver ascends to the surface (1 atm) from a pressure of 5 atm, the volume of the dissolved gas bubbles in the diver's blood will increase by a factor of ____ during the ascent?
- You want to reach a high boiling point in an aqueous system, so you increase the pressure in the reaction flask. You find that the water boils at a temperature of 166.8 °C. What is the pressure in the reaction flask? (Given: ΔH°vap(H2O) = 43.4 kJ/mol) (Show work please, and to 1 decimal place)Show complete solutions and enclose all final answers in a box. Round off final answers to 4 decimal places and use floating values for intermediate answers. A gas column is separated into two segments by a non-permeable partition. On the first segment is 1.63 moles of Helium with volume V1 and on the second segment is 3.84 moles of Oxygen gas with volume V2. Consider both gases to be ideal and at the same pressure P and temperature T. If the partition is removed, calculate the change in entropy of the gaseous system.A student caried out this experiment and obtained the following data: Patm = 656.7 mm Hg Vinitial = 0.30 mL Mass of Alka-Seltzer sample = 0.123 g TH2O = 27.0°C Vfinal = 17.05 mL Determine the following: a. What is the balanced chemical equation for this reaction? (Hint: See Equations 1-4.) b. What is the vapor pressure of water? c. What is the partial pressure of carbon dioxide?

Some of the butane gas was used and after some time, the pressure had gone down to 50 psig. If the temperature is 250C, what fraction of butane had been used?
- 3.00mL of a hydrogen peroxide solution is used in this experiment and 36.00mL of oxygen gas is trapped in the apparatus. The air temperature is 23.0oC. What is the mass% of H2O2 in the solutionWhich of the following deviations from the experiment could cause a decrease in the calculated mass of Mg(s)? Not accounting for the vapor pressure of water. Using a beaker with a wider diameter. Incorrectly recording the barometric pressure. Using a eudiometer of different length.
