What else can I help you with?
Is a new substance is produced a chemical or a physical change?
That's a chemical change because the structure of the atoms are changing. Chemical features can only be viewed through chemical change, by the way.
Is a physical change the only way to break down a compound?
No, a compound can also be broken down through a chemical change. This typically involves a chemical reaction that alters the chemical structure of the compound to create different substances.
Is water boiling in a pan a physical or chemical change?
It depends on what is boiling. If you are boiling WATER, then it is NOT a chemical change, it is a physical change (change of state from liquid to gas). If you are cooking food on the stove, a chemical change is occuring. That is, the chemical bonds within the food molecules are actually changing. One way you can tell that it is a chemical change is that you can't "uncook" food, but you can condense steam back into water.
What is one way of knowing chemical change has happened?
There may be a change in color, a change in temperature, formation of a gas, formation of a precipitate, a new odor, or a solid may disappear.
What is one way you might be able to determine if it is a physical change?
One way to determine if a change is physical is if the substance changes its form or appearance without altering its chemical composition. For example, melting or freezing a substance, dissolving it in water, or changing its state of matter are all physical changes.
What is one way that a chemical change can happen in a household?
Cooking involves chemical changes.
Is burns in the presence of oxygen physical or chemical change?
The process of burning in the presence of oxygen is that of a chemical change. It is a chemical change and not a physical change because the prodects do not have the same properties as the reactants.
Identify one way that Americans wanted political change?
Obama was elected as Americans wanted a change in direction; instead of more of Bush and his friends.
What is one or two letters called that represent an element?
The chemical symbol is one or two letters that represent an element.
When a new substance is produced is it a chemical or physical change?
That's a chemical change because the structure of the atoms are changing. Chemical features can only be viewed through chemical change, by the way.

What is a symbolic way to write out a chemical change?
Writing out a chemical equation for a specific chemical reaction.
Is a physical change the only way to break down a compound?
No, a compound can also be broken down through a chemical change. This typically involves a chemical reaction that alters the chemical structure of the compound to create different substances.
What is the chemical symbol again mean?
A chemical symbol is a shorthand way to represent an element. It consists of one or two letters that help identify the element in the periodic table and chemical formulas. For example, the chemical symbol for oxygen is "O" and for gold is "Au."

How can you identify a one way street?
