<p>Let's post some questions guys</p>

2

<p>does anyone know the answers to these questions?</p>

<ol>
<li>the energy diagram of A-B in the T/F section. was the rate raster A to B than B to A?</li>
<li>the graph of Hydrogen adding to Oxygen to form water?</li>
<li>(#8) is Al the one that acts as both acid and base?</li>
</ol>

3

<ol>
<li><p>Since the reaction was exothermic, it is spontaneous, so it reacts at a faster rate than the reverse reaction, which is endothermic and non spontaneous.</p></li>
<li><p>it goes up then becomes horizontal, because oxygen was the limiting reactant</p></li>
<li><p>Al(OH)3 is amphoteric</p></li>
</ol>

4

<p>for the matching section what did u guys put for ph being 7 and ph being under 6</p>

5

<p>Let’s compile a list…
I’ll start with some of what I remember.</p>

<p>1.___mL 1.0M [strong base] required to neutralize 100mL of 1.0M [monoprotic weak acid]… 100mL
2. Petroleum, fractional distillation, b/c of different boiling points… T, T, CE
3. The one with the different lab equipment, buret (C) was the answer for two of them.</p>
