What does that mean NH3 H2O NH4OH?
ammonia (NH3) dissolves in water (H2O) to form ammonium hydroxide (NH4OH)
Does CO2 (g) plus H2 (g) H2O (g) plus CO (g) represent an enthalpy of formation?
This is an exothermic reaction.
What H2O(l) plus heat H2O(g) exthermic or endothermic?
It is an exothermic reaction. There are multiple ways to think about this. The reactants are in the gas phase and thus have a lot of energy within the molecules. When they react to produce a liquid, which has much less energy in its molecules. The energy must be released to the environment to lower the energy of the bonds.
Explain Why a reaction is exothermic or endothermic because of bond energies?
the reaction is OH ç CH3 CH = CH CH2 CH3 + 2 H2O ® CH3 CH CH CH2 CH3 ç OH
What type of reaction is CH4 plus 2O2 equals CO2 plus 2H2O plus 218kcal?
The given equation represents a combustion reaction, where methane (CH4) reacts with oxygen (O2) to form carbon dioxide (CO2) and water (H2O). The release of 218 kcal indicates that this reaction is exothermic, releasing heat energy.
Does H2O plus CaCl2 is it endothermic or exothermic?
When H2O reacts with CaCl2, it is an exothermic reaction because it releases heat to its surroundings. This is because the formation of bonds in the products is stronger than the bonds in the reactants, resulting in the release of energy in the form of heat.
Is h2o plus energy to h2 plus o2 an exothermic reaction?
No, the reaction of water (H2O) with energy to produce hydrogen gas (H2) and oxygen gas (O2) is an endothermic reaction because it requires energy input to break the bonds in water molecules.
What type of chemical reaction is NH4OH equals NH3 plus H2O?
Decomposition
Is the dissolving of sodium thiosulfate in water endothermic or exothermic reaction?
The dissolving of sodium thiosulfate in water is an exothermic reaction. This means that heat is released during the process as the sodium thiosulfate molecules form bonds with water molecules.
What is the reaction of sodium bicarbonate and hydrochloric acid is endothermic or exothermic?
Neutralisation reaction will take place. HCl + NaHCO3 ---> NaCl + H2O + CO2
What is the temperature of naoh plus H2O exothermic reaction?
36oC
What does that mean NH3 H2O NH4OH?
ammonia (NH3) dissolves in water (H2O) to form ammonium hydroxide (NH4OH)
What is the equation for the solution in water NH4OH?
NH4OH < == > NH3 + H2O, it is a weak base
Is Na2CO3 H2O endothermic or exotermic reaction?
If formed out of elements C + O2 it is exothermic (heat, fire); But as degradation of complex compounds it depends on the compound used and other product formed, but a lot of degradations are endothermic (needs high temperatures and stops after heating is stopt, it cools 'itself' down)
What does NH4OH decompose into?
NH4OH decomposes into ammonia (NH3) and water (H2O). Ammonium hydroxide is an unstable compound that readily breaks down into these simpler substances.
What is a balanced equation for hydrochloric acid with ammonium hydroxide?
The balanced equation for hydrochloric acid (HCl) with ammonium hydroxide (NH4OH) is: HCl + NH4OH → NH4Cl + H2O.
Is the metabolism of carbohydrates endothermic or exothermic?
The metabolism of carbohydrates is exothermic, meaning it releases energy in the form of heat during the various biochemical processes involved in breaking down carbohydrates to produce ATP for cellular energy.
