If a substance is an element is it a pure substance or a mixture?
There are two ways to think about this. Chemically, the element is a pure substance (each atom has the same number of protons). Nuclear speaking, the element may be represented by a number of different isotopes (different number of neutrons).
What are three ways sedimentary rocks can form?
Biologically, Chemically and Mechanically.
What are four ways you can detect chemical reaction?
Precipitation formsProduction of bubblesTemperature changeColor change
What causes substance to combine in different ways to make other substance?
The forming or breaking
What are some ways the density of a substance can be increased and decreased?
The increase in concentration increases the density and decrease causes the decrease in density.
What are four ways to detect that chemical change has occurred?
A chemical change occure when one or more substance are changed in to new substances that have different properties

Is there three ways you could chemically change a piece of fruit?
There are almost an infinite number of ways to change a piece of fruit chemically. As an example, three ways would be: 1) Cooking the fruit at high temperature 2) Immersing the fruit in strong acid 3) Immersing the fruit in strong alkali All processes are irreversible; it is impossible to regain the original piece of fruit after the process is performed because its chemistry has changed.
What are the four ways a change of state occurs?

What occurs when atoms link together in new ways to create a substance different from the original substances?

What natural factors can change a population?

A glowing splint placed in a test tube causes a loud pop Is this chemical or physical change?
Its a chemical change because a gas is produced (which is one of the signs of chemical reaction)
What are some ways of changing solid materials?
The following are ways to change the size and shape of a solid material without forming a new substance, except one. Which one is it?
What are two ways to change the state of a substance?
Substances can change state, usually when they are heated or cooled. For example, liquid water turns into steam when it is heated enough, and it turns into ice when it is cooled enough. The closeness, arrangement and motion of the particles in a substance change when it changes state.
