Chemical properties of matter are classified into three groups which are the ability to rust, flammability, and reactivity. Which of the following BEST defines Reactivity?

• Reactivity is the ability of matter to change shape according to its temperature

• Reactivity is the ability of matter to react chemically with other substances.

• Reactivity is the ability of matter to resist external forces such as weathering

• Reactivity is the inability of matter to react chemically with other substances

Which property depends on the the amount of matter present?

• extensive

• intensive

• hardness

• mass

Which of the following is a example of extensive property?

• color

• density

• temperature

• weight

Suppose you have two white powders (Baking powder and baking soda) an you want to distinguish the two. How would you identify the given materials without tasting them?

• get their masses

• place them in water then observe

• touch them one by one

• none of the above

Using their properties mixtures can be separated too. When iron and wooden match mixed and you wish to separate them, how would it be possible?

• place them in water

• use magnet to attract the iron

• dissolve them in water

• get their densities

How can a mixture of sand, salt, water and paper be separated?

• I, II, and III

• II, I, and III

• III, II, and I

• III, I, and II

To what classification of properties of matter do the hardness, temperature , color, size, and smoothness belong to?

• State of matter

• Chemical Properties

• Physical Properties

• Elements and compounds
