Suppose that after delivery several drops of the water cling to the inner wall of the pipette (because the pipette is dirty). How does this technique error affect the reported density of water?
5.0 g of H2O at 23.0 oC is added to 100.0 g of H2O at 67.5 oC. What is the temperature of the resulting mixture
Explain how this model can be used to reduce the number of dangling bonds from 49 (unreconstructed) to 19 (constructed). B. Explain the origin of the name dimer adatom stacking fault.
Metabolic regulation is achieved via regulating enzyme activity in 3 ways: allosteric regulation, covalent modification, and enzyme synthesis/degradation.
Write the expressions for Kc for the following reactions. a. 2O3(g) --> 3O2(g) b. Ti(s) + 2Cl2(g) --> TiCl4(l) c. 2C2H4(g) + 2H2(g) --> 2C2H6(g) + O2(g)
why are the rates of diffusion of carbon monoxide and nitrogen gas are virtually identical at the same temperature?

How many moles of HCl are required to react with 0.610 g of Al(OH)3 in the above unbalanced reaction? Use at least as many significant figures in your molar masses as in the data given.
how would i calculate the equilibrium bond length from knowing Bo B1 the equilibrium rotational constant and the vi-rot coupling constant?
What mass of NaCl must be dissolved in 65.0 grams of water to lower the freezing point by 7.50 °C? The freezing point depression constant, Kfp, for water is -1.86 °C/m. Assume the van't Hoff factor for NaCl is 1.87.
