Answer:
It is more important because of the freedom.
Explanation:
While at home you can do your work of course... but you could lay down, take a nap. You could get on the game, play around. You could draw, and fiddle and dance and do WHATEVER you want with no teacher to stop you so you have to be your own motivation. You have to be your own teacher or its VERY easy to fail.
Answer:
temperature of the reaction vessel
Explanation:
temperature of the reaction vessel
The boiling point of water at 1 atm is 100 degrees celsius. However, when water is added with another substance the boiling point of it rises than when it is still a pure solvent. This called boiling point elevation, a colligative property. The equation for the boiling point elevation is expressed as the product of the ebullioscopic constant (0.52 degrees celsius / m) for water), the vant hoff factor and the concentration of solute (in terms of molality).
ΔT(CaCl2) = i x K x m = 3 x 0.52 x 0.25 = 0.39 °C
<span> ΔT(Sucrose) = 1 x 0.52 x 0.75 = 0.39 </span>°C<span>
</span><span> ΔT(Ethylene glycol) = 1 x 0.52 x 1 = 0.52 </span>°C<span>
</span><span> ΔT(CaCl2) = 3 x 0.52 x 0.50 = 0.78 </span>°C<span>
</span><span> ΔT(NaCl) = 2 x 0.52 x 0.25 = 0.26 </span>°C<span>
</span>
Thus, from the calculated values, we see that 0.75 mol sucrose dissolved on 1 kg water has the same boiling point with 0.25 mol CaCl2 dissolved in 1 kg water.
.2135 mol of Ba(OH)2 are needed to neutralize .427 mol of 2HC2H3O2
<span>When electrons shared unequal atoms such as hydrogen
and oxygen atom, one atom will get more of the common electrons and it will be slightly
negatively charged. The other atoms who gets less electron will be slightly
positively charged. This chemical condition describes water as a polar
molecule. The oxygen atom pulls the shared electrons more strongly than do the
hydrogen atoms within each of the two polar covalent bonds.</span>
