How many objects can you insert into a hash table before you have a greater than 50% chance to have a collision between any two objects if n=100? Assume all hash values are equally likely.
In the short-term Consumption can be greater than Income. Explain why the reason is more financial than economic.
Sodium amide, NaNH_2, when dissolved in water, produces a solution with pH greater than 7. Explain this observation using appropriate chemical equations, Lewis structures, and "arrow-pushing".

The problem is for part (c) below.Thank you.Calculate [H+] for each of the following solutions,and indicate whether the solution is acidic, basic, orneutral.(a) [OH -] = 0.00041 M M ---Select---acidicbasicneutral(b) [OH -] = 2.5 10-9 M M ---Select---acidicbasicneutral(c) a solution in which [OH -] is 100 times greater than[H+]Your answer differs from the correct answerby orders of magnitude. M ---Select---acidicbasicneutral
If the pH of the solution is greater than the pKa, the predominant species in the solution will be O protonated O deprotonated
