The mixture can be separated into three separate components by using a centrifuge and a separating funnel.
A centrifuge is used to separate a solid that is held in suspension by a liquid. In this case a solid dissolved in water. In contrast, a separating funnel is used to separate two immiscible liquids.
-First take the flask containing the two immiscible liquids and pour contents in to a closed separating funnel.
- The most dense liquid will settle at the bottom, then open the separating funnel valve to collect contents of dense liquid into a flask.
- The remaining liquid on the separating funnel can be collected in a different flask.
-Now take the liquid that is a solution of a solid in water and pour in a test tube. Place the contents in a centrifuge.
- Centrifuge at high speed until the solid sinks to the bottom of the test tube, then decant the liquid into a flask and the solid remains in the test tube
Answer:
The answer is choice (4) 268 g.
Explanation:
To find this answer you have to go to the reference table, using Table G, and go to KNO3 at 70°C. Find out how many grams saturate potassium nitrate (134 g). Then you double it (268 g ) because it's asking for grams at 200 grams of water.
The correct answer is B,
<span>It is endothermic, with both positive enthalpy and entropy changes.</span>
Im not sure but i think its 350. I really hope im right
Answer:
96.5 g/ml
Explanation:
If 5g is 19.3 then 25g is 19.3x5 which is 96.5 g/ml
