copper + sulphur = copper sulphide!

it's been a while since I've done chemestry, so bear with me.

the reaction works out as CuS + O2 = Cu + SO2 , if i read your word equation correctly, which would make the reactants copper sulphide and oxygen.

There is no elemental iron (Fe) involved in this reaction, neither as reactant (iron sulphide -FeS- plus oxygen are) nor as product (iron oxide (FeO) plus sulphur dioxide are)

what is the reaction for the equation for carbon dioxide

Carbon dioxide is a compound (can be reactant or product). We do not say that carbon dioxide is a chemical reaction.

Carbon Dioxide and Water -------> Sugars + Oxygen

2CuS + 3O2 ---> 2CuO + 2SO2 Copper Sulphide + Oxygen ---> Copper Oxide + Sulphur dioxide

The products of this reaction are: Carbon Dioxide, and Water The reactant of this reaction is: Carbonic Acid

In this reaction Manganese dioxide does not work as a reactant, whereas it works as a catalyst. It catalyzes the decomposition of Hydrogen peroxide into Water and Oxygen. Here is the balanced chemical equation for this reaction:2 H2O2 --MnO2--> 2 H2O + O2

The reactant is SO3 and the products are SO2 and O2. See the Related Questions link to the left for how to write a balanced chemical reaction.

6CO2 + 6H2O ---> C6H12O6 + 6O2Carbon dioxide and water.

There are two reactants in the photosynthesis "equation": the carbon dioxide : 6CO2 and water : 6H2O

CO2,g + Cs --> 2COg is the chemical reaction equation.

2C2H2 + 5O2 --> 4CO2 + 2H2OThis is a classic combustion reaction, where oxygen is one reactant, and carbon dioxide and water vapor are your products.

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.

Word equation for photosynthesis: carbon dioxide + water ---in the prescence of sunlight and chlorophyll --> glucose + oxygen Balanced symbol equation: 6CO2 + 6H2O ---> C6H12O6 + 6O2 Therefore the reactant gas is carbon dioxide and the product gas is oxygen.

In a chemical equation, Reactants --> Products For example, aerobic respiration. Glucose + Oxygen --> Carbon Dioxide + Water C6H12O6 + 6O2 --> 6CO2 + 6H2O Glucose and Oxygen are the reactants of the reactions and Carbon Dioxide and Water are the products of the reaction.

Chemical equation between the reaction of carbon dioxide and lime water is, CO2 + Ca(OH)2 -------> CaCO3 + H2O

In the equation for cellular respiration the reactants, which go into the equation, are glucose and oxygen. The products, that come out of the equation, are carbon dioxide, water, and energy in the form of ATP.

A reactant is something that reacts with another thing(s) in a word equation to make something else (the things made are the 'products'). So an example is:CARBON + OXYGEN -> CARBON DIOXIDE + WATERCarbon and oxygen are the reactants and carbon dioxide and water are the products.This word equation as a symbol equation is:C + O2 -> CO2 + H20

2C4H10 + 13O2 ---------> 8CO2 + 10H2O This is a combustion reaction because carbon dioxide and water are products. This equation is balanced because on both sides there are 8 carbon atoms, 20 hydrogen atoms, and 26 oxygen atoms. Also these are the lowest possible coefficients (because there cannot be fractional coefficients). The trick to balancing this equation is to realize that the oxygen reactant is diatomic (so it starts out as O2).

2ZnS + 3O2 ---> 2ZnO + 2SO2 Zinc sulphide + Oxygen ---> Zinc oxide + Sulphur dioxide This reaction is endothermic and requires a heat change (H) in order to happen. As the Zinc sulphide reacts with the oxygen the zinc becomes oxidised (oxidation, zinc atoms bond to oxygen atoms), and during this reaction sulphur dioxide is given off.

Actually, manganese dioxide is a catalyst that speeds up the reaction but does not get consumed in the reaction and is not part of the reactants or products
