What happens when CO2 reacts with H2O?
Carbon dioxide dissolves in water and slowly reacts with water to produce carbonic acid.
What is the chemical equation for CO2 H2O?
CO2+H2O—->C6H12O6+O2+H2O.
What is the standard enthalpy of the reaction CO H2O –> CO2 H2?
The standard enthalpy of reaction is +2.85 kJ.
What kind of chemical reaction is this?

What happens when CO2 combines with hydrogen?
The Sabatier reaction or Sabatier process produces methane and water from a reaction of hydrogen with carbon dioxide at elevated temperatures (optimally 300–400 °C) and pressures (perhaps 3 MPa) in the presence of a nickel catalyst.
What is the name of the acid formed when carbon dioxide gas is passed into water?
Carbon dioxide (CO2) forms carbonic acid when dissolved in water.
Is H2 CO2 endothermic or exothermic?
exothermic
The reaction is highly exothermic, which is more than enough to break bonding in carbon dioxide and water molecules and to still have excess thermal energy.
Is co H2O CO2 H2 endothermic or exothermic?
CO + H2O (g) = CO2 + H2 +41.2kJ/mol (1.9) Reactions (1.8) is endothermic whereas reaction (1.9) is exothermic. In order to supply the large endothermic reaction heat and to maintain that high temperature around 1200K, additional heat is supplied through fossil fuel combustion.
How does CO2 and h20 interact to form H2CO3?
Abstract. Carbonic acid (H2CO3) forms in small amounts when CO2 dissolves in H2O, yet decomposes rapidly under ambient conditions of temperature and pressure. Despite its fleeting existence, H2CO3 plays an important role in the global carbon cycle and in biological carbonate-containing systems.
What determines which way this chemical reactions goes CO2 H2O ↔ H2CO3 ↔ H+ HCO3?
CO2 and water form carbonic acid or H2CO3, which is in equilibrium with bicarbonate (HCO3-)and hydrogen ions (H+). A change in the concentration of the reactants on either side of the equation affects the subsequent direction of the reaction.
What are the 5 types of reactions in chemistry?
This becomes much easier for students to do when they learn the pattern of 5 basic categories of chemical reactions: synthesis, decomposition, single replacement, double replacement, and combustion.
