What else can I help you with?
What changes the rate of a chemical reaction or allows a chemical reaction to occur?
Heat?
What is always involved when physical or chemical changes occur in matter?
When physical changes occur in matter, the substance's state or appearance changes without altering its chemical composition. In contrast, chemical changes involve a modification in the substance's chemical composition, resulting in the formation of new substances.
What changes take place by themselves without any help?
Natural phenomena such as erosion, evaporation, and the changing of seasons occur without any external assistance. These changes are driven by physical and chemical processes inherent to nature.
Which occurs more often on earth physical changes or chemical changes?
Physical changes occur more often on Earth compared to chemical changes. Physical changes involve alterations in the state or appearance of matter without changing its chemical composition. Examples include changes in shape, size, or state of matter (solid, liquid, gas). Chemical changes involve the formation of new substances with different chemical properties.
Is changes in energy a chemical change?
Changes in energy themselves are not considered chemical changes. Instead, changes in energy may occur as a result of a chemical change taking place, such as in an exothermic or endothermic reaction where energy is either released or absorbed.
Does chemical changes almost never occur in nature?
no
Physical or chemical changes that occur in exposed crustal material through the activity of the forces of nature is?
erosion
Examples of chemical changes in the nature?
Examples of chemical changes in nature include wood burning in a forest fire, photosynthesis, the formation of sulfuric acid in volcanic vents, and the fixing of nitrogen in lightning bolts and bacteria.
What comes out of a reaction?
Chemical changes occur after a chemical reaction.
What are the chemical changes in frosty glass?
Any chemical change occur.
What are the chemical of weathering?
it harms the environment. temperature changes and climate changes occur because of chemical weathering.
What changes the rate of a chemical reaction or allows a chemical reaction to occur?
Heat?
What is always involved when physical or chemical changes occur in matter?
When physical changes occur in matter, the substance's state or appearance changes without altering its chemical composition. In contrast, chemical changes involve a modification in the substance's chemical composition, resulting in the formation of new substances.
Can chemical change and physical change happen simultaneously?
No, chemical changes and physical changes are distinct processes that occur separately in a system. Chemical changes involve the formation of new substances with different chemical properties, while physical changes involve alterations in the state or appearance of a substance without changing its chemical composition. These processes do not typically occur simultaneously.
What changes take place by themselves without any help?
Natural phenomena such as erosion, evaporation, and the changing of seasons occur without any external assistance. These changes are driven by physical and chemical processes inherent to nature.
What is it called when changes occur when bonds form between atoms?
A chemical reaction, a chemical change.
Which occurs more often on earth physical changes or chemical changes?
Physical changes occur more often on Earth compared to chemical changes. Physical changes involve alterations in the state or appearance of matter without changing its chemical composition. Examples include changes in shape, size, or state of matter (solid, liquid, gas). Chemical changes involve the formation of new substances with different chemical properties.
