<p>Metallic solids have high electrical conductivity and heating ability.</p>
<p>Ionic solids don’t conduct ****. Only their solutions do</p>
<p>What was the one with hydrogen and oxygen and being mixed and then allowed to return to their normal temperature?</p>
<p>was the helium average velocity or kinetic energy?</p>
<p>which question was this? a t/f?</p>
<p>no it was asking about helium in a balloon and then the oxygen/hydrogen one was around #57ish</p>
<p>what was the t/f q with the the color not changing because it was at equilibrium or something and then there being no changes at equilibrium …was that ttce?</p>
<p>Fairly certain that the helium one was the pressure is created by the helium atoms bouncing against the inner walls of the baloon.</p>
<p>Sugar dissolves in water…The answer for the sugar/sand question was the option to add water (dissolves sugar) and then filter (separates sugar solution from sand), I believe.</p>
<p>i agree with chessy on the helium question</p>
<p>which was the boiling point and which was the critical point? wasnt the boiling point the one parallel to 1 atm? and the critical the one above which the liquid didnt exist (was this e?)</p>
<p>Agree with Cheesy and Slothz.</p>
<p>Color changes only for some not for all solution mixtures.</p>
<p>Example : Common Salt solution + Sugar solution = No color change. Transparent ( I think )</p>
<p>Critical point is E ( The highest point in the liquid - gas phase change line ).</p>
<p>Boiling point is B or D ?( The point on the same line as the critical point but at a lower temperature)</p>
<p>so, trollaunty, what was the answer to that question?</p>
<p>what was the one for hydrogen and oxygen being mixed to make water and then cooled to its original temperature? I put 2 L of hydrogen</p>
<p>wait a sec, D was on the same line as the critical point but at a lower temperature…B was more toward the liquid</p>
<p>actually the boiling point was D. It goes from liquid to gas, B was from solid to liquid</p>
<p>SO it went like this:</p>
<p>At equilibrium there is no change in color in the solution BECAUSE at the molecular level, nothing changes or something like that. (I may be messing up hard.)</p>
<p>so chessy, youre agreeing that q is ttce?
i tried searching it up but no luck</p>
<p>I think it was f,t. The question said There is no change in a solution if color doesn’t appear</p>
<p>evelyn, but they mentioned that it was at equilibrium, which is why i chose T. dont take my word for it tho.</p>
