The cornstarch and water mixture acts like a solid sometimes and a liquid at other times. This concoction is an example of a suspension (a mixture of two substances), one of which is finely divided and dispersed in the other. ... When you slap the cornstarch quicksand, you force the long starch molecules closer together.

A mixture contains O2 at 700. torr pressure, F2 at 500. torr pressure, and Cl2 at 500. torr pressure. What is the total pressure
Softa [21]

You have to use Dalton's law of partial pressure for this question. Dalton's law of partial pressure basically states that the total pressure of the system is all of the partial pressures of the components added together. Therefore to answer the question you just need to add all the patial pressures together meaning that the total pressure would be 700+500+500=1700.

The answer would be 1700 torr.

I hope this helps. Let me know if anything is unclear or if you have any further questions.

Four stereoisomers exist for 4-hexen-3-ol. Draw the structure of the isomer that has the Z configuration around the double bond
butalik [34]

Answer:

Following are the solution to the given question:

Explanation:

Please find the complete question and its graph file in the attachment file.

The isomer having Z specification from around dual connector as well as the chiral center S structure is:

(3S,4Z)-4-Hexen-3-ol

An 'H' atom has been at the level of 3rd carbon, and we need to change its configuration, through 'R' to 'S' by CIP notation (under contrast to -OH group).
