Java socket related classes to create a dictionary client To get familiar with the socket library in Java,
• Establish a connection with a DICT server, and receive the initial welcome message.
• Finish a connection with a DICT server by sending a final QUIT message, receiving its reply, and closing the socket connection.
• Requesting, receiving, parsing and returning a list of databases used in the server. Each database corresponds to one dictionary that can be used to retrieve definitions from. Examples include one or more regular English dictionaries, a Thesaurus, an English-French dictionary, a dictionary of technical terms, a dictionary of acronyms, etc. In the interface, the user will have the option of selecting a specific database, or all databases.

Prove that continuous function of a continuous function is continuous.
write a pseudo code for a program to find the greater number between two numbers
palisade cells near the top of the leaf contain many chloroplasts. Which of the following best explains why?
3. If iron filings were an impurity present along with the ASA in this
experiment, at which point in the recrystallization procedure would they
be removed completely from the ASA? (What slide numbers show this
procedure?)
4. What is the purpose of adjusting the polarity in slide 19 of the slide
presentation?
5. Would benzoic acid dissolve better in water, or in ethanol? Explain why
using the concepts discussed in this laboratory.
1. In a final very careful and correct recrystallization from acetone, benzoic acid (pure mp 122-122.3°C) was melted on a melting point machine immediately after vacuum filtration and washing, and found to have a melting point of 116-121°C. Why is the melting point not 122-122.3°C? Assume that there are no solid compounds present other than benzoic acid present, and suggest what may be present to affect melting point, and what role that presence does.
2. What are 2 advantages of using gravity filtration over vacuum filtration when removing a solid impurity from a hot mixture?
