400

This number is the sum of the number of protons/electrons and the number of neutrons

What is Atomic Mass?

400

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.)

400

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)?

400

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?

500

This subatomic particle does not contribute significant mass to an atom.

What is the electron?

500

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.)

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.
