Words: Iron (III) oxide reacts with hydrogen gas produces solid iron and water.
Symbols: Fe2O3 + H2 --> Fe + H2O
Balanced final equation: Fe2O3 + 3H2 --> 2Fe + 3H2O Remember:
- Hydrogen is diatomic so you need the subscript 2 when in gas form.
- This is a single displacement reaction.
Carbon (C) + Oxygen (O2) = CO2
The balanced equation for the reaction is: 2Na2O + 2CO2 -> 2Na2CO3 This is a double displacement reaction, where the sodium from sodium oxide replaces the carbon in carbon dioxide to form sodium carbonate.
copper is a metal and carbon dioxide is a gas so therefore dont mix
The balanced chemical equation for the reaction between silicon and carbon dioxide to form silicon carbide and silicon dioxide is: 3Si + 3CO2 -> SiC + 2SiO2
The balanced chemical equation for the reaction is: CS2 + 3O2 -> CO2 + 2SO2. This shows that 1 molecule of carbon disulfide reacts with 3 molecules of oxygen gas to produce 1 molecule of carbon dioxide and 2 molecules of sulfur dioxide.
The balanced equation for the reaction between silicon dioxide (SiO2) and carbon (C) to form silicon carbide (SiC) and carbon monoxide (CO) is: SiO2 + 3C → SiC + 2CO
The balanced equation for ethanol (C2H5OH) burned in air is: C2H5OH + 3O2 -> 2CO2 + 3H2O. This equation shows that ethanol reacts with oxygen to produce carbon dioxide and water.
Carbon (C) + Oxygen (O2) = CO2
This balanced equation represents a combustion reaction, where a fuel (C4H10) reacts with oxygen gas (O2) to produce carbon dioxide (CO2) and water (H2O).
The balanced equation for the reaction is: 2Na2O + 2CO2 -> 2Na2CO3 This is a double displacement reaction, where the sodium from sodium oxide replaces the carbon in carbon dioxide to form sodium carbonate.
The balanced chemical equation for the reaction between copper carbonate (CuCO3) and hydrochloric acid (HCl) is: CuCO3 + 2HCl → CuCl2 + H2O + CO2. This equation shows that copper carbonate reacts with hydrochloric acid to form copper (II) chloride, water, and carbon dioxide.
The balanced equation is: 2HCl + CaCO3 -> CaCl2 + H2O + CO2
copper is a metal and carbon dioxide is a gas so therefore dont mix
The balanced equation for the burning of carbon in air is: C + O2 -> CO2. This equation shows that one molecule of carbon reacts with two molecules of oxygen to produce one molecule of carbon dioxide.
The balanced chemical equation for the reaction between silicon and carbon dioxide to form silicon carbide and silicon dioxide is: 3Si + 3CO2 -> SiC + 2SiO2
The balanced chemical equation for the reaction is: CS2 + 3O2 -> CO2 + 2SO2. This shows that 1 molecule of carbon disulfide reacts with 3 molecules of oxygen gas to produce 1 molecule of carbon dioxide and 2 molecules of sulfur dioxide.
Sodium phenoxide reacts with carbon dioxide to form sodium salicylate and water.
