Which would be safer if exposed to a flame, a gas can full of gasoline or a can with half air and half gasoline? Explain.
To help you explain your answer, look up the meaning of "isoelectric point" and discuss the effect that pH will have on the structure of your product.
What is the resulting pH of this solution? b. The OCl- form of this acid is less effective as a disinfectant
Calcium hydride reacts with a vast excess of water to form calcium hydroxide and hydrogen gas. How many grams of calcium hydride
Imagine you want to determine the binding constant for a reaction. You know you will need to generate data to calculate the binding constant.
When you go on the protein databank and look at the Ramachandran plot, it gives you 4 plots (general case, glycine, proline, and pre-proline).
You need 70.2J to raise the temperature of 34.0 g of ammonia, NH3 (g), from 23.0C to 24.0C. Calculate the specific heat of ammonia.
