I need help with question 4&5. thanks
Suppose you are renting a car in Canada and get a flat tire. The tire states it should be inflated to a pressure of 240 kPa, however you only have a tire gauge that reads in psi. To how many psi should you inflate your tires? 3. Chlorine gas can be generated by adding concentrated hydrochloric acid to manganese(IV) oxide according to the following balanced equation 4. MnO2(s) + 4HCl(aq) â MnCl2(aq) + 2H20() + Cldg) How many moles of Cl2 gas can be generated by reacting 1.50 mL of 1 with excess Mn02? a. b. What volume would this much Cl2 occupy at 25°C and 760 mm Hg? 5. Ocean water contains about 4.2 g of salt (which you can assume to be NaCI) for every 125 g of water. Using Î7,--kim and using 1.86 °C*kg/mol for the cryoscopic constant, estimate the freezing point of ocean water. I reactions lab, magnesium metal will react with a 0.1 M solution of hydrochloric acid to produce hydrogen gas: Mg(s) + 2HCl(aq) â MgCl2(aq) + H2(g) What effect will each change have on the rate of this reaction (faster, slower, or no effect)
