its simple, seeing as how you are breaking a compound down which consists of 2 pure substances. Means that there is a chemical change via taking one pure substance out which will inturn change it chemically and physically
What else can I help you with?
A chemical change combining two elements result in?
compound
What forms when two elements join during a chemical change?
a compound
What event must take place to separate a compound into separate elements?
A chemical reaction must occur to separate a compound into its separate elements. This may involve breaking the bonds holding the elements together within the compound, typically through the addition of energy or the introduction of another reactant.
What type of change is needed top break down a compound?
A chemical change is needed to break down a compound into simpler substances. This typically involves breaking the chemical bonds holding the atoms together in the compound through reactions like decomposition or hydrolysis.
What chemical changes involve breaking and making chemical bonds?
Breaking of bonds but also formation of new bonds.
What substance can only be broken down by chemical change?
A substance that can only be broken down by chemical change is a compound. Compounds are made up of different elements chemically bonded together, and breaking these bonds requires a chemical reaction. Physical changes, such as melting or dissolving, cannot break compounds down into their individual elements.
When an electric current passes through water takes place breaking down the compound into hydrogen and oxygen. a physical change an atomic change a chemical change an elemental change?
When an electric current passes through water, it breaks down the compound into hydrogen and oxygen, which is known as electrolysis. This process involves the breaking of chemical bonds and the formation of new substances, indicating a chemical change. Thus, the correct answer is a chemical change.
How can a chemical change help tell the difference between a element and a compound?
its simple, seeing as how you are breaking a compound down which consists of 2 pure substances. Means that there is a chemical change via taking one pure substance out which will inturn change it chemically and physically
Is it a chemical change when a compound splits into its original elements?
Yes, that would be a decomposition reaction.
Which substance can be broken down by a chemical change The answer is Hexane--but why?
Hexane is a compound. All chemical compounds can be broken down by chemical change (chemical reactions of many types) - not only hexane. All the other choices are elements which cannot be broken down by chemical changes.
Does the chemical makeup quartz ever change?
No chemical formulas ever change. If there are different elements in a compound, it ceases to remain the same compound, and becomes a new compound.The chemical formula for quartz is SiO2. That is, always was, and always will be the chemical formula for quartz.
Are compounds broken down into elements by chemical or physical change?
its a chemical change. a physical change does not change the chemical makeup of a substance. it simply changes its form or physical state. examples: ice melting, a tree being chopped down.
