What else can I help you with?
Why is the boiling of water a physical reaction and not a chemical reaction?
During boiling the chemical composition is not changed.
What occurs in light reaction?
A.T.P. and N.A.D.H are formed during light reaction.
Which of these occurs during an endothermic reaction?
energy is absorbed
What colour dous it change to during the reaction?
what colour change occurs during the calcium and hydrochloric acid reaction
What occurs in light-dependent reaction?
A.T.P. and N.A.D.H are formed during light reaction.
What occurs when elements and compounds interact to produce a new substance with new properties?
This is a chemical reaction; the composition of reactants is changed.
What type of change occurs in a chemical reaction?
In a chemical reaction, a chemical change occurs where the chemical composition of the substances involved is altered, leading to the formation of new substances with different properties. This change involves the breaking and forming of chemical bonds.
Is it possible for a composition reaction to also be a combustion reaction?
A composition reaction (sometimes also called a combination reaction.
What happens when a physical reaction occurs?
During a physical reaction, the arrangement of atoms and molecules changes, but no new substances are formed. This means that the chemical composition remains the same before and after the reaction. Examples of physical reactions include changes in state (solid to liquid, liquid to gas) or changes in shape.
When elements or molecules combine to form a new compound what reaction it occurs?
When elements or molecules combine to form a new compound, a chemical reaction occurs. This process involves the rearrangement of atoms to create new bonds and result in a different composition than the original substances.
What reaction occurs during light dependent reaction?
During light dependent reactions chlorophyll and other light-aborbing molecules capture energy from sunlight.
How often does a change in the composition of matter occur during a chemical reaction?
A change in the composition of matter occurs during every chemical reaction. This involves the breaking and forming of chemical bonds, leading to the rearrangement of atoms to create new substances with different properties.
