Change of shape can not be used to indicate a chemical reaction has happened. Examples of evidence of a chemical reaction are changes in odor or color.
You write the name over the arrow in the chemical equation.
Yes, "aq" is commonly used in chemistry to indicate that a compound is dissolved in water, meaning it is in an aqueous solution. It helps to specify the state of the compound in a chemical reaction or formula.
Yes, a catalyst can be re-used, because It is NOT actually used in a chemical reaction. A catalyst will increase the rate of reaction by attracting reactants, but the catalyst is not a reactant. However, the reuse cannot be done indefinitely then, depending on the severity of the reaction conditions, it can be occur a small, but accumulative deactivation of the catalys.
This chemical reaction is called neutralization.
What is the chemical reaction of a dispoiable lighter
The arrow that is used to indicate a reverse or backward reaction in a chemical equation is called a double-headed arrow.
The symbol used in a chemical equation to indicate yields is the arrow "->". This arrow separates the reactants from the products in a chemical reaction.
You write the name over the arrow in the chemical equation.
The coefficients in a chemical equation indicate the relative number of moles of each reactant and product involved in the reaction. They are used to balance the equation so that the law of conservation of mass is upheld, ensuring that atoms are neither created nor destroyed during a chemical reaction.
State symbols in chemical equations are used to indicate the physical state of the substances involved (solid, liquid, gas, or aqueous solution). This information is important because the physical state can affect the reaction conditions and the behavior of the substances in the reaction. Including state symbols provides a more complete and accurate representation of the chemical reaction.
The symbol that means "produces" in a chemical reaction is an arrow pointing to the right (→). This arrow is used to show the direction in which the reactants are transformed into products during a chemical reaction.
Yes, "aq" is commonly used in chemistry to indicate that a compound is dissolved in water, meaning it is in an aqueous solution. It helps to specify the state of the compound in a chemical reaction or formula.
An equals sign is not used in a chemical equation because it implies a mathematical equality, while a chemical equation represents a chemical reaction where atoms are rearranged to form new substances. Instead, chemical equations use an arrow to indicate the direction of the reaction.
The double dagger symbol in chemical notation is used to indicate a specific type of reaction mechanism known as a concerted reaction. This symbol is important because it helps chemists understand and represent complex chemical reactions more accurately and efficiently.
The symbol "->" (arrow) is used in a chemical equation to indicate produces or yields.
Yes, a catalyst can be re-used, because It is NOT actually used in a chemical reaction. A catalyst will increase the rate of reaction by attracting reactants, but the catalyst is not a reactant. However, the reuse cannot be done indefinitely then, depending on the severity of the reaction conditions, it can be occur a small, but accumulative deactivation of the catalys.
Symbols are used for the graphical representation of a chemical reaction.
