Design a word guess game. Ask player 1 to input a word. Then player 2 guesses the word. If the
guessed word is not correct, program says \"Your guess is not correct!\". Player 2 can guess
unlimited times until the answer is correct, or type \"@exit\" to quit the program. When player 2
types \"@hint\", print out the first and last letter of the word. When players 2 types \"@hint\"
again, randomly tells one of the other unknown letter. After this, every time player 2 input
\"@hint\", randomly tells one of the other unknown letter until no more unknown letters. If the
guess is correct, print out \"Yes! ! ! ! !\"
Solution
from random import randint
word=raw_input(\"Player 1:Enter word\ \")
guess=\"\"
flag=0
while guess!=word:
guess=raw_input(\"Player 2:Enter guess word\ \")
if guess==\"exit\":
break
elif guess==\"hint\" and flag==1:
print word[randint(0,len(word))]
elif guess==\"hint\" and flag==0:
print word[0],word[len(word)-1]
flag=1
elif guess==word:
print \"Yes\ \"
else:
print \"Your guess is not correct\ \"

Determine the molecular geometry of CO32â».Solution .pdf
1. Determine the molecular geometry of CO32â».
Solution
The Lewis dot structure fir carbonate is a central carbon single-bonded to two
oxygens and double bonded to the third oxygen. This is one of three equivalent resonance
structures, i.e., each of the oxygens could be the C=O bond. So the central carbon has three
substituents attached to it (the three oxygens), The VSEPR geometry for three substituents
around a central atom is the triangle (planar). This geometry gets the three C-O bonds as far apart
as possible (120 degrees).
