Atom & Eve
The subatomic particle that resides in the nucleus and has no electrical charge
What is a neutron?
A solution that has dissolved as much solid material as possible
What is a saturated solution?
The two main reactants in our Fizz Quiz reaction in cups / Ziploc bags
What were baking soda and calcium chloride (and water)?
What is evaporation?
The chemicals that result after a chemical reaction
What are products?
The part of an atom where you would find neutrons and protons
What is the nucleus?
What is mass (of solute) per volume (of solvent)?
In the chemical reaction of CaCl2 + Baking soda, this was what we reacted with the precipitate to confirm the identity of the product.
What is vinegar?
The liquid part of a solution
What is solvent?
What is formation of a gas, formation of a solid (precipitate), temperature change, and color change?
This number represents the number of protons in an atom (or the number of electrons)
What is Atomic Number?
Which is the least concentrated solution?
A) 50 g of salt in 100 ml of water
B) 55 g of salt in 115 ml of water
C) 30 g of salt in 57 ml of water
What is B?
An event when the atoms of reactant molecules rearrange to form product molecules.
What is a chemical reaction?
A method to separate mixtures
What is filtering?
What are reactants?
This number is the sum of the number of protons/electrons and the number of neutrons
What is Atomic Mass?
The procedure to determine which of two solutions (same solvent and solute) is more concentrated
AMV: What is comparing equal volumes of solutions and determining the heavier solution is more concentrated?
(1. Put 50 ml of one solution on one side of a balance
2. Put 50 ml on the other side of the balance
3. Whichever solution is heavier has more mass and is therefore more concentrated.)
The 3 products of our Fizz Quiz reaction in a cup / Ziploc bag, which we isolated over several days of experiments
What are chalk (as precipitate), sodium chloride (as solid crystals), and carbon dioxide (gas)?
A solution with a low hydrogen concentration
What is a base?
In a chemical equation, the number and kind of atoms of reactants is __________ ____ the number and kind of atoms of products.
What is equal to?
This subatomic particle does not contribute significant mass to an atom.
What is the electron?
The procedure to determine amount of solute dissolved in solvent of a mystery solution.
AMV: What is comparing equal volumes of the solution with water, adding gram pieces to water until balance is equal on both sides, and counting gram pieces to find the mass of solute in the mystery solution?
(1. Take 50 ml of the “mystery” solution, put it on one side of a balance.
2. Next, take 50 ml of water and put it on the other side of a balance.
3. Add gram pieces to the 50 ml of water until the balance is equal on both sides.
4. Count the number of gram pieces that you put into the water. This is equal to the mass of the solute in the mystery solution.)
What is the chemical formula or chemical name for the solid precipitate of our reaction of CaCl2 + baking soda?
What is calcium carbonate (CaCO3)?
The 4 steps to separate a mixture of powder, salt, and gravel
What is...
1. First, add water and stir to dissolve the salt.
2. Then use the screen filter to separate out the gravel.
3. Then use a coffee filter to remove the powder.
4. Last, allow the water to evaporate to isolate the salt.
Which of the following is not an example of a chemical reaction?
A) water vaporizing
B) copper rusting
C) red cabbage juice changing color in vinegar
D) boiling eggs
What is A?
