Which of the following shows the conservation of mass during cellular respiration? a. 3 c o2 + 3 h2 o + energy → 3 c6 h12 o6 + 3 o2 b. 6 c o2 + 6 h2 o + energy → c6 h12 o6 + 6 o2 c. c6 h12 o6 + 6 o2 → 6 c o2 + 6 h2 o + energy d. 6 h2 o + c6 h12 o6 → 6 o2 + energy

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.1 m below the tank bottom which is a = 7.4 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute)
