<p>i missed around 20 and omitted 10-15. good enough for 650+? =[</p>
<p>I Don't Remember Exact Number Though (TTCE)</p>
<p>Q) If two gases put on the 2L box, then what will the total pressure?</p>
<p>O2 = 1atm, 4L
N2 = 4atm, 1L </p>
<p>(Is it right question?)</p>
<p>(A) 1
(B) 2
(C) 4
(D) 6
(E) 8</p>
<p>i put B ......</p>
<p>Nuclear transformation: Th → Pa (?)
Oxidation: C → CO2
Reduction: _____ → __</p>
<p>Have +2 or +3 charge: Fe? (something located in transition metal)
Liquid at room temp. : Br?
Iron, sand...... something: using Magnet?
___<em>1</em><em>→</em><strong><em>2</em></strong> this reaction is endothermic and about Le Chatelier's Principle principle. (if want to make 2 increasing, what should do?)
(A) increase volume
(B) Decrease temp....
........
Modern Periodic: atomic number
About Alcohole boiling....Iron rusting...........(question: which is increase entropy? and question: which is not chemical reaction??? or not redox???)
1L and 1M of NaCl? dilute in 2L distilled water, what will the concentration of NaCl?</p>
<p>There were two questions that asked Calculate pH.... 0.01M NaCl question and 0.01M HCl ? ....??? what was it???</p>
<p>about..... 3M HNO3 coloress solution?! compares with 15M HNO3 yellowish solution?!</p>
<p>what was the answer? </p>
<p>is that kind of HNO3 ....... depends on Molarity???? (E)</p>
<p>Is there something number of molecular...</p>
<p>a. 0.05(6.02<em>10^23)
b. 0.5(6.02</em>10^23)</p>
<p>is it (a)?</p>
<p>and ...... on part A ..... something about "bubble in the water..........." do you guys remeber the question?</p>
<p>So
So2
S2o3????? This Kind Of Question</p>
<p>What Was The Answer?</p>
<p>IS THERE ANSWER "alpha particle?"</p>
<p><strong><em>Al + excess S ???? what is the answer </em></strong>?</p>
<p>(a) 1
(b)2
(c) 3
.....</p>
<p>is there the answer 300g? about NO ..........
becuse of 10mole.....????</p>
<p>there is something 64% H2O???? and I think i got 9g ?????
16*4....that's why 4 moles and 100-64= 36...and then 36/4 = 9.. is it right?</p>
<p>and 8g ......and 3.4g????? something something....what was it?</p>
<p>ok for the bubbling, i put the gas was H_2, b/c i've seen that same question on an AP chem problem</p>
<p>i got S<em>2 O</em>3</p>
<p>i got .05(6.02*10^23)</p>
<p>i got Fe for the 2+, 3+ charge</p>
<p>I got decrease temp for le chatliers</p>
<p>I got 300g for NO</p>
<p>Iron rusting is increase in entropy (it's spontaneous)</p>
<p>er, lemme try to remember the others....</p>
<p>acid or base solution never pour to the water (T) becuase acid or base can be spiltter or something.....(T) .....(CE)?</p>
<p>Banzen is cyclic hydrocarbon (T) / Banzen has only single bond (F)</p>
<p>benzene is cyclic but it has half double bonds, half single bonds, so TF</p>
<p>for the acid splashing thing, i got TTCE as well</p>
<p>something 18kJ -> becuase of 2mole 18*2 = 36kJ?</p>
<p>don't remember</p>
<p>Both Ionic & Covalent bond..... NH4Br OR CaBr2</p>
<p>Don't use in TITRATION lab -> Crucible?</p>
