You place salt into one beaker of water and corn starch into another beaker of water. You notice that the corn starch takes much more time to dissolve than the salt. You could conclude this in comparing the solubility of salt vs. starch in water?
What is the salt is MORE soluble than the starch.
300
This is not a common indicator of a chemical change. A. irreversible B. a change of state C. a new substance is formed D. a gas is given off
What is a change of state?
300
This best describes the characteristics of a gas? A. The volume, but not the shape of a gas, is determined by its surroundings B. Neither the shape nor volume of a gas is determined by its surroundings C. The shape and volume of a gas is determined by its surroundings D. The shape, but not the volume of gas, is determined by its surroundings
What is C. - The shape and volume of a gas is determined by its surroundings
300
A type of matter in which there is only one type of particle.
What is a pure substance?
400
A clear liquid is given to you in a test tube. You bring the liquid to a boil using a Bunsen burner and realize that the vapour leaving the test tube is water vapour. You then observe after all af the water has evaporated that crystals are left behind in the test tube. You would classify the contents of the test tube as this. A. Heterogeneous Mixture B. Compound C. Solution D. Element

This is an explanation for why sugar dissolves more readily in warm water than cold.
What is the warmer the particles, the faster the particles are moving and thus the faster they are able to separate the sugar particles?

What is photosynthesis?
500
This is an explanation according to KMT of why compressed gasses require sturdy containers. (Think about what happens to the particles)
What is the same number of high energy gas particles are contained when compressed as would be in a much larger container that is not compressed. As a result there is a great deal of force pushing outward (pressure) on the container and it must be strong enough to push back?
500
A slow process in which metals react with oxygen to form metal oxides and leads to disintegration is known as this.
What is Corrosion?
