When is the principle of conservation of mass true?
B. Only for reactions that take place in closed systems.
Hope this answers your question!
I think the correct answer from the choices listed above is option C. The statement that best explains why a crystal is incompressible would be that there is little, if any, space left between its adjacent molecules. Hope this answers the question. Have a nice day.
Answer:
33.3gtts/min
Explanation:
We can find the drops/minute with common proportions.
100cc/1hr * 200gtts/1cc * 1hr/60min ≈ 33.3gtts/min
Best of Luck!
The answers that apply include;
- A saturated fatty acid with a greater molar mass has a higher melting point than a saturated fatty acid with a low molar mass
- A saturated fatty acid has a higher melting point than an unsaturated fatty acid
Saturated acids do not have double bonds in their hydrocarbon tails. Therefore, because there are no kinks in the chains, the chains are well compacted due to numerous hydrogen bonds between each. The larger the chains (directly proportional to molar mass), the higher the melting point of these fats.
The answer is B. Centrifugation
