I need to write this prediction sheet to identify an unknown You will write up a prediction sheet that lists all of the unknowns and the possible tests you could use with the expected results. HINT: Always begin with solubility

Possible unknowns:

1. Pentane

2. Cyclohexene

3. 1-Pentanol

4. 2-Pentanol

5. 2-Methyl-2-Propanol

6. Pentanal

Reagents or Items:

Vegetable Oil

3M H2SO4

Bromine in Vinegar

5% K2Cr2O7

Acetone

ZnCl2 in concentrated HCl (Lucas reagent)

1% KMnO4

6M HCl

pH paper

Benedict's Reagent

Tollen's Test reagent (plus neutralizing reagents)

fire could start, buildings collapsing, and ash falling from the sky.

explanation:

this is because the buildings or plants could catch on fire and the buildings would most likely collapse. lastly ash would fall because all the burning would cause ash to fall from the sky.

hope this .

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
