FINAL

Chemical Reactions 100Chemical Reactions 100

Physical or Chemical Change:Boiling Water

What is a physical change? (change only in the state of matter)

Chemical Reactions 200Chemical Reactions 200

Physical or Chemical Change:Burning Wood

What is chemical (burning anything is a chemical change)?

Chemical Reactions 300Chemical Reactions 300

The Law of Conservation of Matter/Mass:“Matter cannot be….”

What is “Matter cannot be created nor destroyed, it only changes

form”?

Chemical Reactions. . .400Chemical Reactions. . .400

Two signs a chemical reaction took place when we added the reactants water and an antacid (alka-seltzer) in a test

tube:.

What are a color change and production of a gas?

Chemical Reactions 500Chemical Reactions 500

We add two substances together, each with a mass of 50 grams. One substance seems to disappear while another new substance is created. The mass of the result of this

reaction will be…

What is the mass we started with, 100 g?

Charge it Up 100Charge it Up 100

What side of the water molecule would be attracted to the positive side of another molecule

What is the negative side?

Charge it Up 200 Charge it Up 200

. Water is a polar molecule because it has two different ends. What we call these ends…

What is positive (+) and negative (-)?

Charge it Up 300 Charge it Up 300

The conductivity meter will only light up (electricity will flow) when a compound has

these...

What is charges?

Charge it Up 400Charge it Up 400

Two objects, a test tube that is negatively charged and a knife is positively charged, both attract

water. What we can tell about the water’s charges:

What is that water must have both positive and negative

charges?

Charge it Up 500Charge it Up 500

Why wax does not dissolve in water.

What is wax is not polar but water is polar? (wax has no charged ends like

water)

Bonding 100Bonding 100

When one atom wants electrons more than another, but is still willing to share them, this is the bond that results…(think Tug of War)…

What is polar covalent? (like water)

Bonding 200Bonding 200

When one atom REALLY wants the electrons more than another and they are transferred

over, this type of bond is the result…

What is ionic? (like NaCl with its positive and

negative ions)

Bonding 300Bonding 300

When electrons are shared equally, this type of bond is the result:

What is NON-polar covalent? (no atom wants the electrons much more

than the other

Bonding 400Bonding 400

Two atoms are bonding. Oxygen’s electronegativity is 3.4. Carbon’s electronegativity is 2.6. What type of bond these two atoms create?

What is a polar covalent bond? (the difference is 0.8, large enough to

share electrons unequally)

Bonding 500Bonding 500

What job does Mrs. Radford’s husband do?

What is an instructional coach (you can say “teacher”) at Kent

Meridian?

Potpourri 100Potpourri 100

If we added baking soda and vinegar in a bag, how the mass after the reaction compares to the mass

before the reaction:

What is the mass is the same before and after the reaction? (Law of

Conservation of Mass)

Potpourri 200Potpourri 200

Giving off or absorbing heat is a sign of this:

What is a chemical reaction? (What were the other signs?)

DAILY DOUBLEDAILY DOUBLE

Though wax does not dissolve in water due to its lack of charged ends, water is able to dissolve salt

(like NaCl). This is how it works:

What is that water has both positive and negative ends that will attract the positive and negative ions in salt?

Potpourri 400 Potpourri 400

When two different substances are added together and atoms are rearranged, this is the result:

What is a different compound?

Potpourri 500Potpourri 500

If two atoms are on very opposite sides of the periodic table, what their difference in

electronegativities will be like:Bonus: what type of bond they will create:

What is the difference in electronegativity will be large?

Bonus: Ionic bond
