Nitrile gloves are preferred in general chemistry labs because they:

Safety Data Sheets (SDS) are written by:

SDS provides more detailed hazard information than:

When diluting acid, you should always:

Which equipment should you use with volatile chemicals?

Food and drinks in the lab are:

Long hair in the lab should be:

Acids should be stored:

Flammables should be kept away from:

Oxidizers like KMnO4 should be stored:

Compressed gas cylinders must be:

Safety Data Sheets are an important resource for:

Qualitative data refers to:

Quantitative data examples include:

Data should be recorded:

Precision refers to:

A measurement can be precise but not:

The uncertain digit in a measurement is the:

When reading a liquid's volume, measure at the:

Graphs help us:

The x-axis represents the:

The y-axis represents the:

The graph's title should:

To show overall data trends, use a:

Storing chemicals safely includes:

SDS contains information about:

Percent error and uncertainty are part of:

Goggles protect your skin from chemical splashes.

Lab coats prevent clothes from absorbing spills.

Gloves should always be removed inside the fume hood.

SDS gives less information than a label.

It’s safe to smell chemicals directly.

Always add acid to water, not water to acid.

Volatile chemicals must be handled in a fume hood.

Eating or drinking in the lab is allowed if careful.

Long hair should be tied back.

All chemicals can be stored together safely.

Oxidizers should be stored away from flammables.

Flammables should be stored near heat sources.

Compressed gas cylinders must be upright and secured.

Qualitative data uses numbers.

Quantitative data uses measurements with units.

Precision means closeness to the true value.

Accuracy means repeatability of results.

The last digit in a measurement is uncertain.

Measurements can have zero uncertainty.

The meniscus should be read at the bottom.

Graphs help visualize relationships between variables.

The dependent variable is plotted on the x-axis.

The title of the graph is not important.

Chemicals must always be labeled with names and hazard symbols.

SDS documents are prepared by students.

Nitrile gloves are resistant to many chemicals.

Accuracy depends only on the instrument.

Data should always include units.

It's okay to work alone in the lab if you are careful.

Recording data during the experiment prevents loss of information.
