Measure It
This is the SI temperature unit.
What is the kelvin?
This state has both a definite shape and a definite volume.
What is a Solid?
Traditional litmus turns this color in a basic solution.
What is blue?
A pure substance made of only one kind of atom is this.
What is an element?
Horizontal rows in the periodic table have this name.
What are periods?
2,000,000 in scientific notation.
What is 2 x 10^6?
Water in its gaseous state is called this because water is normally liquid at room temperature.
What is a vapor?
Antacids for heartburn is this type of substance.
What is alkaline?
Two or more different elements chemically joined in a fixed ratio form this.
What is a compound?
Vertical columns in the periodic table have this name.
What are groups?
This property is calculated by dividing mass by volume.
What is density?
This state contains charged particles produced when a gas becomes ionized.
What is plasma?
According to Brønsted–Lowry theory, an acid donates this particle.
What is a proton (hydrogen ion, H+)?
Oil-and-vinegar dressing with separate layers is this type of mixture.
What is heterogeneous?
Mendeleev left empty spaces in his table for this reason.
What is allowing for elements that had not yet been discovered?
Two objects have equal mass, but object A occupies half the volume of object B. This describes A’s density compared with B’s.
What is twice the density?
A solid changing directly to a gas undergoes this process.
What is sublimation?
A water molecule that accepts a proton becomes this ion.
What is hydronium (H₃O⁺)?
A mixture with uniform composition throughout is called homogeneous, or this other name.
What is a solution?
One of these elements were discovered after Mendeleev created his draft of the periodic table that were predicted by him.
What is gallium, scandium, or germanium?
After collecting measurements, scientists perform this step to look for patterns in the data.
What is analyzing the data?
A color change alone cannot prove a chemical change. This must form for the change to be chemical.
What is a new substance / product?
These values are the limits of the pH scale (mostly).
