• B.

It is 5 cm long.

• C.

It is 12.3 g.

• D.

### To find the density of an object you would need to known the mass and the _______________

• A.

Volume

• B.

Weight

• C.

Composition

• D.

Unit of measurement

A. Volume
Explanation
To find the density of an object, you would need to know the mass and the volume. Density is defined as mass divided by volume. Therefore, in order to calculate the density, both the mass and volume of the object are required. The weight, composition, and unit of measurement are not directly related to finding the density of an object.

### A quantitative observation involves conditions that can be

• A.

Measured

• B.

Heard

• C.

Felt

• D.

Tasted

A. Measured
Explanation
A quantitative observation involves conditions that can be measured. This means that it involves collecting data or information that can be expressed numerically or in terms of quantity. It focuses on obtaining precise measurements or values, such as length, weight, temperature, or time. This type of observation allows for objective analysis and comparison of different variables or phenomena.

### From the l labs we have done the past few days we know that  ...

• A.

Some matter dissolves in water and some does not

• B.

Some matter is mixtures of different substances

• C.

Some mixtures can be separated

• D.

D. All given answers are correct
Explanation
The statement "all given answers are correct" is a valid explanation because it summarizes the information provided in the question. The question states that from the labs done in the past few days, it has been observed that some matter dissolves in water and some does not, some matter is mixtures of different substances, and some mixtures can be separated. Therefore, all of the given answers are correct as they align with the observations made in the labs.

• A.

Chemicals are always toxic

• B.

• C.

All chemicals are safe

• D.

Everything made of matter is a chemical.

D. Everything made of matter is a chemical.
Explanation
The correct answer is "Everything made of matter is a chemical." This statement is true because all matter, whether it is natural or man-made, is made up of chemicals. Chemicals are the building blocks of matter and can be found in everything around us, including the air we breathe, the water we drink, and the food we eat. Therefore, everything that exists in the physical world is composed of chemicals, making this statement true.

Explanation
The periodic table is a systematic arrangement of all the known elements in the universe. It provides a comprehensive overview of the fundamental building blocks that make up everything in the universe, including both natural elements and their compounds. By organizing the elements based on their atomic number, properties, and electron configurations, the periodic table allows scientists to study and understand the relationships and patterns among different elements, enabling further exploration and discovery in various fields of science.

### The space that matter takes up is its

• A.

Volume

• B.

Mass

• C.

Weight

• D.

Density

A. Volume

Volume refers to the amount of space that an object occupies. It is a measure of the three-dimensional extent of an object. Mass, weight, and density are all related to the physical properties of matter, but they do not directly indicate the space that matter takes up. Therefore, volume is the correct answer in this context.
