<p>yeah i got 4 TTCE</p>
<p>what were hard questions for you guys??</p>
<p>^icecubes123, what was primary consitituent of glass? was it SiO2? and for plant fertilizer, NH4NO3… right</p>
<p>yes yes! i got 4 TTCEs 
Feeling a bit hopeful</p>
<p>What did you guys get on the practice tests? I also got SiO2(100% right) and NH4NO3(I think its wrong). What did you get on the fertilizer one?</p>
<p>Edit: I got 5 TTCE’s…do you remember which ones you put for TTCE?</p>
<p>I got NH4NO3 for Fertilizer! What did you get for main cause of OZONE Destruction?</p>
<p>omg my paper had nothing to do with plant fertizers 
What about the question where they asked what doesnt change when sugar is dissolved in water.Was it density?</p>
<p>adding sugar has no effect on conductivity since it does not dissociate. at least that’s what I thought.</p>
<p>Well I thought the density would not change. By the way there was equation on fertilizers? why didn’t I see it.</p>
<p>I didn’t have a question on fertilizers either… or glass… :S</p>
<p>No fertilizer or glass for me…but I did have the sugar one!</p>
<p>what about the question with the mass of carbon 12 and hydrogen 2 and they asked us for the coumpound’s formula,i put C3H6</p>
<p>yep that’s right</p>
