To provide an accurate answer, I would need more context about the specific reaction you are referring to, including the reactants and products involved. If you could provide details about the reaction or the substances already present, I’d be glad to help identify the missing substance.
What else can I help you with?
What substance would need to be added in order to reverse the reaction?
To determine the substance needed to reverse a specific chemical reaction, one must consider the products and the reaction conditions. Generally, adding the reactants or a catalyst that promotes the reverse reaction can help shift the equilibrium back. For example, if the reaction is exothermic, increasing temperature might favor the reverse reaction. Additionally, applying Le Chatelier's principle can guide the choice of substances to reverse the reaction efficiently.
If thermal energy must be added to a chemical reaction for the reaction to take place the reaction is a Exothermic b Reactant c Balanced d Endothermic?
If thermal energy must be added to a chemical reaction for the reaction to take place the reaction is endothermic.
Is sweating a chemical reaction?
Sweating itself is not a chemical reaction. Sweating is the body's mechanism to regulate body temperature by releasing sweat, which is mainly composed of water and electrolytes. However, the process of sweat production by the sweat glands involves cellular processes within the body, which are chemical reactions.
What key feature must a chemical equation have for it to be classified as a combustion reaction?
The product must be oxidized, i.e, Oxygen must be on the reactant side. Also, the reactant will form its oxide and also liberate heat energy. In case of hydrocarbons, Carbon Dioxide, water and heat energy will be liberated and it is a must when writing the chemical equation.
Which pairing matches the type of substance with the item in donates?
To accurately pair a type of substance with the item it donates, one must consider the substance's properties and its role in a reaction or process. For example, an acid donates protons (H⁺ ions) in a chemical reaction, while a base donates hydroxide ions (OH⁻). In the context of solutions, a solute donates its molecules to a solvent to create a homogeneous mixture. Each pairing highlights the specific donating action of the substance in question.

What must be added to a reactant to start a chemical reaction?
Either an energy source to start the reaction or a catalyst.
If thermal energy must be added to a chemical reaction for the reaction to take place the reaction is a Exothermic b Reactant c Balanced d Endothermic?
If thermal energy must be added to a chemical reaction for the reaction to take place the reaction is endothermic.
If heat must be added to a chemical reaction for the reaction to take place the reaction is?
Endothermic reactions need heat. Exothermic reactions give off heat.
Why must HCl be added to the solid after the reaction with zinc is completed?
To reduce the zn5+ to zn2+
When polysaccharides are divided into monosaccharides what molecule must be added?
water must be added and the process is called Hydrolysis
Can a chemical reaction occur without any new substanced?
No, in order for a chemical reaction to take place, a new chemical substance must be formed.
What group of organisms must be added to any food chain or food web to form a complete food cycle?
Decomposers must be added to any food chain or food web to form a complete food cycle.
Is burning a physical Change changes?
It's an exothermic reaction (oppose to an endothermic reaction). It's combustible reaction, (this is an example of chemical reaction) where a substance must combine with oxygen to produce, heat and light; or Burn.
What number must be added to the polynomial to complete the square x2-5x?
-3
What number must be added to the polynomial to complete the perfect square x2-24x?
144
Is burn a physical change?
