Answer:
Large change in temperature makes heat flow fast.
Explanation:
Answer:
Gas liquid solid
Explanation:
gases have a weak potential since they have a weak bond between molecules while in solids it's the strongest making them vibrate in a fixed position
Answer:
E) 0.90
Explanation:
In TLC (Thin-Layer-Chromatography) retention factor RF is defined as the ratio between distance of the sample and the solvent front. RF is very important in chemistry to know the composition of any sample by comparison.
In the problem, as the sample has a distance of 0,20cm from the solvent front, the distance of the sample is:
2,0cm - 0,20 cm =<em> 1,8 cm</em>. Thus, RF is:
RF = 1,8cm / 2,0cm = 0,90
<em>E) 0,90</em>
