Is vinegar and salt a chemical change?
Vinegar (acetic acid solution in water) and salt (sodium chloride) are compounds, not"changes".
What kind of change occurs with no new substance being formed?
physical changes
Synthesis reactions invole?
Synthesis reactions involve a change in one or more of the compounds, elements, or materials that are being synthesized.
What are the safety precautions of compounds?
Safety precautions for use with chemical compounds depend entirely on what particular compounds are being used, and how they are being stored and handled.
What are the Definitions of chemical and physical changes?
A physical change is a change in the physical state of a substance. An example of a physical change is water turning to ice (a solid) when frozen. Its state of matter has changed, but it is still the same substance (water).A chemical change is a change in the chemical structure of a substance(s). For example, when oxygen and magnesium react, they form magnesium oxide (a different substance). The chemical state of both the oxygen and magnesium atoms involved has changed.Equations:Oxygen + Magnesium --> Magnesium OxideO2 + 2Mg --> 2MgO
What type if change results in a new substance being formed?
chemical
Can a compound be formed by chemical processes such as combusion?
Definitely, yes. In fact all compounds may be thought of as having been formed by chemical processes, one these processes being combustion. And combustion almost always results in the formation of chemical compounds. For example, if you burn the metal magnesium in oxygen the compound magnesium oxide is formed.
What is a chemical that increases the rate of reaction with out being part of the compounds being formed?
This substance is called catalyst.
What is the differences and similarities of a compound and a mixture?
Both are formed from atoms. A compound cannot be divided in atoms by physical procedures.The mixture being formed from compounds can be divided in compounds by physical procedures.
What kind of change occurs with a new substance being formed?
Chemical change.
Is vinegar and salt a chemical change?

What kind of change occurs with no new substance being formed?
physical changes
The change that results in a species being well suited to its environment is known as?
adaptation
What chemical reaction does not result in a new substance being formed?
phisical change
A physical change is best defined as?
a process that does not change the chemical composition of a substance. A change in a substance with no new substances being formed
Why are metal alloys an example of a physical change and not a chemical change?
They are a physical change because it is not like burning where a new substance is being formed.
Is baking brownies change or a chemical change?
chemical! new substances are being formed, heat is created, and odors are produced.
