What else can I help you with?
How do you know that a chemical change took place when sodium and clorine join to form table salt?
it is an ionic and exothermic reaction i.e. when it will take place heat will be liberated
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.
Can a chemical reaction take place in which energy is absorbed or released?
no
Can a chemical reaction takes place in which energy is neither absorbed released?
no
Can a chemical reaction take place in which energy is neither released nor absorbed?
no
Can a chemical reaction reaction take place in which energy is neither absorbed or released?
no
Where does most chemical digestion take place and nutrients are absorbed into the blood?
chemical digestion takes place in the small intestine large intestine,mouth and stomach. Nutrients are absorbed in the small intestine and minerals in the large intestine.
Energy is neither created nor destroyed in a chemical reaction Explain where the energy released or absorbed by the reactions comes from or goes to?
Energy released by a chemical reaction is released as heat to the surroundings thus rising the temperature of the room or lab etc where the reaction is taking place. Similarly, energy absorbed by endothermic is either supplied by external heating of reaction mixture over a flame or absorbed from surroundings.
Can a change in matter take place without energy being released or absorbed?
No, a change in matter can't take place without energy being released or absorbed? Why? Well, this is because every chemical or physical change in matter includes a change in energy. You can't change matter without a change in energy. Energy is the ability to do work or cause change. Hope you find this helpful. And yes, this answer has been approved by my science teacher.
If a piece of metal bubbles was place in acid is that a chemical change?
No, it is not a chemical change. For example, if you put gold bubbles into any single acid, no chemical change will take place.
What identifies a chemical change has taken place?
Signs that a chemical change has taken place include the formation of a gas, the formation of a precipitate, a change in temperature, and a change in color.
When cheese is cut into a slices does a chemical formula takes place.?
I assume you mean chemical "change" and the answer is no, it is a physical change that takes place.
