Substances X, Y, and Z are elements.

Chemical W is a pure substance.

Substances X, Y, and Z are compounds.

A student finds a beaker containing a substance in the laboratory. The student filters the contents of the beaker and notices that a solid is left on the filter paper. What can the student conclude about the type of matter of the original material?

The original material was a mixture.

The original material was a compound.

The original material was either an element or a compound.

The original material was either a mixture or a compound.

The atomic arrangements of two substances (A and B) are shown in the diagram. Which statement describes one of the substances correctly ?

Substance B is a compound as the atoms can be separated only by chemical processes.

Substance A is an element as atoms are not combined chemically.

Substance A is a compound as two different types of atoms are present.

Substance B is a mixture as the atoms can be separated by any physical process.

A student hypothesizes that the compound, hydrogen peroxide, shares the properties of the individual atoms that make it up, hydrogen and oxygen. The table shows the data that the student gathers. Does the data support the student’s hypothesis?

No. The elements are at different phases than the compound at room temperature.

Yes. The names of the elements are incorporated into the name of the compound.

Yes. The boiling points of the elements combined define the boiling point of the compound.

No. The elements and the compound are all dangerous due to their stability factors.

A student designs an animation to visualize how the particles in a substance change when heat is added. How can the teacher verify that the animation is accurate?

Adding heat creates the effect of increased spacing between particles.

Adding heat creates the effect of increased particle size.

Adding heat creates the effect of decreased spacing between particles.

Adding heat creates the effect of decreased particle size.

When heat energy is added to water in a pot on a stove, what changes occur to the water?

Particles move faster, and temperature increases.

Particles move slower, and temperature increases.

Particles move faster, and temperature decreases.

Particles move slower, and temperature decreases.

The image shows two different atomic models made by two students. What can be concluded about the models?

Model 2 is accurate because it shows protons and neutrons at the center of the atom and electrons in orbits around the center.

Both models are accurate because they show protons and electrons inside the nucleus.

Model 1 is accurate because the numbers of protons and electrons inside the atom are the same.

Both models are accurate because they contain positively charged protons and negatively charged electrons.

A student receives three materials and must determine whether each is a metal or nonmetal. To do this, the student performs three tests on each material. First, the student cleans each material, examines the surface, and records any observations. Next, the student takes a small sample of each material, strikes the sample with a hammer, and records any observations. Lastly, the student attaches a piece of wax to a long, thin sample of the material and heats the end opposite of the wax. The student records the amount of time it takes for the wax to melt. The table shows the results of the three tests. Based on the student’s observations, how should the materials be classified?

Materials 1 and 3 are metals, and Material 2 is a nonmetal.

Material 1 is a metal, and Materials 2 and 3 are nonmetals.

Material 2 is a metal, and Materials 1 and 3 are nonmetals.

Materials 2 and 3 are metals, and Material 1 is a nonmetal

Referring to the reference periodic table, what do the elements fluorine, chlorine, and bromine have in common?

All have the same number of valence electrons.

All are located in the same period.

All are halogens, so they are not very chemically active.
