What else can I help you with?
What substances influence other molecules without being changed themselves?
I think what you are looking for is a catalyst. A catalyst lowers the energy or activation for a reaction, allowing it to happen faster. During the reaction nothing actually happens to or changes the catalyst.
What are goggles used for in a science lab?
To protect the eyes from harmful substances o chemicals that they may be in contact with during a lab
How does large variations between day and night temperatures cause weathering?
During the warm day, things expand from the increased heat. During the cold night, things contract as heat is lost. This process of expansion and contraction creates cracks and other stress points that cause weathering.Hence the temperatures cause weathering. Note: There are few substances that this expansion and contraction can be seen with the naked eye, but even the minute changes cause weathering, and when substances like water get into the microscopic cracks then freeze, it magnifies the effects as water expands when it freezes while other substances contract when they cool down.
What is the new substances that are formed during physical change?
in a physical change, no new substance is formed. for example liquid water. You freeze it, it becomes ice. when you boil it, it evaporates into steam. HOWEVER. Steam, ice, or liquid, it is STILL water. You only form new substances in chemical changes: cooking/burning food, reacting chemicals etc. : )
Is plastic a condoctor?
The term plastic has a broad definition as regards materials. There are thousands of plastics. We often think of plastics as organic polymers, and we will generally find that these materials are not good conductors. Different substances added to plastics during production can change this, but we usually find that plastics do not support current flow, and, therefore, might best be considered insulators rather than conductors.
How is chemical change different from physical change?
During a chemical change the nature of substances is changed.
What is the process called by which matter is actually changed into new substances?
The process by which matter is changed into new substances is called a chemical reaction. During a chemical reaction, atoms are rearranged to form different molecules with new properties compared to the original substances.
What is the term for the substances that are changed during chemical reaction?
You think probable to the reactants.
What is the term for substances that are changed during a chemical reaction?
You think probable to the reactants.
What are some substances that have the explosive sign?
different reactions during explosions
What is a substance that results in a chemical change called?
A substance that results in a chemical change is called a reactant. Reactants are substances that are present at the start of a chemical reaction and are transformed into different substances (products) during the reaction.
How do substances form during a chemical reaction?
Substances form during a chemical reaction through the rearrangement of atoms. Bonds between atoms are broken and new bonds are formed, leading to the creation of new substances with different properties than the original reactants.
What is the process in which One or more substances undergo change to produce one or more new substances with different properties?
This process is called a chemical reaction. During a chemical reaction, bonds between atoms are broken and new bonds are formed, resulting in the creation of new substances with different properties from the original substances.
Are fireworks a chemical change or physical change?
The blast of firecrackers is an illustration of substance change. During a compound change, substances are changed into various substances.
Why do the pigments separate during column chromatography?
Because the retention coefficients of different substances are also different.
Are chemical reactions a chemical change of original substances before a chemical reaction takes a place?
Chemical reactions involve the breaking and forming of chemical bonds in the original substances, resulting in a chemical change. Before a chemical reaction occurs, the original substances have specific chemical properties that undergo transformation during the reaction. The reactants interact to form new products with different chemical compositions.
When new substances are formed from existing substances during a chemical reaction they are known as?
Products.
