Which arrow is used to indicate a reverse or backward reaction in a chemical equation?
The arrow that is used to indicate a reverse or backward reaction in a chemical equation is called a double-headed arrow.
What is the word used to describe a chemical reaction in which energy is released?
Any chemical reaction that releases energy is called an exothermic action. The equations for an exothermic reaction between substance A and substance B would be: A + B --> AB + Heat The heat represents the energy and we can tell it is being released because it is on the product side of the equation. The reverse reaction would be endothermic, meaning it requires energy, heat would be on the reactant side and the equation would be: AB + Heat --> A + B To sum things up, an exothermic reaction releases energy and heat will be on the product side of the equation. An endothermic reaction requires energy and heat will be on the reactant side of the equation.
What symbol is used in a chemical equation to indicate yields?
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.
What term is used for the type of chemical reaction that gives out heat energy?
Exothermic reaction gives free heat (energy).
Is the reaction of magnesium sulphate and water exothermic or endothermic?
The stuff is actually used in some hotpacks. It's exothermic.

How do you indicate that a catalyst was used in a reaction?
You write the name over the arrow in the chemical equation.

Exothermic reaction gives free heat (energy).
Is the chemical reaction for aluminum exothermic or endothermic?
Yes it is. When these two chemicals react, the container they are in becomes heated. Exothermic refers to a release of heat and energy.
Is the reaction of magnesium sulphate and water exothermic or endothermic?
The stuff is actually used in some hotpacks. It's exothermic.
The coeficients in a chemical equation indicate?
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.
What word is used to describe a reaction in which energy is given out?
exothermic
What is the word equation for thermite reaction can be used to weld together?
The thermite reaction can be represented by the word equation: aluminum + iron(III) oxide → aluminum oxide + iron. This highly exothermic reaction produces molten iron, which can be used for welding together steel structures or rail tracks. The intense heat generated melts the iron, allowing it to fuse with the materials being joined.
Does the chemical equation of ATP release exergonic exothermic or absorb energy endergonic endothermic?
The breakdown of ATP into ADP and inorganic phosphate releases energy, making it an exergonic and exothermic reaction. This energy is used by cells for various cellular processes.
Are titrations endothermic or exothermic?
In thermometric titration the reaction enthalpy is used to follow the chemical reaction. I guess it dépends on the titration reaction it can be exothermic or endothermic. ΔHr (molar heat of reaction) negative (indicating an exothermic reaction) or positive (indicating an endothermic reaction
