Yes, new substances are produced in a chemical change or chemical reaction.
There are many examples of this, but one might be the combustion (burning) of hydrogen gas in air. Hydrogen gas will combine with oxygen when it burns, and the result is water. Both hydrogen and oxygen are gases at normal temperature and pressure, and the balanced chemical equation is:
2H2 + O2 => 2H2O

∙ 6y agoAt least partly, yes. When chemical changes take place, some substances (elements, compounds) combine on the molecular level to become different substances. The exact reaction and products depend on the substances, their amounts, and the conditions the reaction occurs in.

Wiki User
∙ 8y agoYes, new bonds are formed resulting in different substances

∙ 13y agoYes. Chemical changes always produce new subtances since the internal structure of the particles of the chemicals is being changed.

Is reacts with acid to form H2 a chemical or physical properties?
Chemical. If a new substance is produced it is a chemical change.
When a substance undergoes a phase change what occurs a particle change a chemical change a new substance is formed a physical change?
When a substance changes phase, this is a physical changerather than a chemical change. When water freezes to become ice, or when ice melts to become water, its all physical.
How do you know if a chemical change has occurred versus a physical one?
If a new substance is produced.
What are products in a chemical reaction apex?
The new substance that are produced
Difference between physical and chemical change?
physical change is a change in matter in which no new substance is formed Chemical change is a change in matter in which new substance is formed
Does chemical change occur when a new substance is produced?
Chemical Change.
If a new substance is produced is it a chemical change?
Correct; a chemical change produces a new substance, or in other words, an existing substance changes into a different substance.
What is the new substance produced in a chemical change?
It depends , how many are produced .
What kind of change in a new substance being produced?
chemical change
What kind of change result in new substance being produced?
chemical change
What kind of change result in a new substance being produced?
chemical change
Is reacts with acid to form H2 a chemical or physical properties?
Chemical. If a new substance is produced it is a chemical change.
Which action would result in a chemical change?
A new substance is produced. Bubbles are given off (fizzing), which shows that a gas has been produced. Color changes. Turbidity (cloudiness) heat/light given off. A sound is produced/an explosion occurs etc
When a substance undergoes a phase change what occurs a particle change a chemical change a new substance is formed a physical change?
When a substance changes phase, this is a physical changerather than a chemical change. When water freezes to become ice, or when ice melts to become water, its all physical.
How do you know if a chemical change has occurred versus a physical one?
If a new substance is produced.
A chemical change is a change in the of a substance....?
A chemical change is a change of the identity of a substance. Or A chemical change is a change of the substances into a new substance.
Why physical change can easily be reversed but chemical change cannot?
Physical changes are generally easy to reverse because NO ENERGY is produced by the substance.A Chemical change cannot be reversed because ENERGY is produced by the substance forming a new substance.
