Given the reaction C2H4 +3 O2 --> 2 CO2 + 2 H20, what is the mole ratio between carbon dioxide and water? 2 mol CO2: 2 mol H2O
1 mol CO2: 3 mol H2O
2 mol CO2: 3 mol H20
3 mol CO2: 2 mol H2O

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
