What properties can you use to identify if a substance is salt, baking soda or cornstarch?

i believe its water, vinegar, and iodine solution... sorry if wrong

Explanation:

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.

- both b and d.

-since b and d are the closest coastlines then that makes it the most affected.

< 3

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
