What else can I help you with?
Is a firecracker exploding an example of an endothermic reaction or an exothermic reaction?
Exothermic Reaction because the fizzing is CO2 being released as heat (energy).
What is the name of the type of reaction that produces heat?
exothermic reactions1) Combustion: A combustion reaction is when oxygen combines with another compound to form water and carbon dioxide. These reactions are exothermic, meaning they produce heat. An example of this kind of reaction is the burning of napthalene:C10H8 + 12 O2---> 10 CO2 + 4 H2O
Which is an exothermic chemical reaction?
An exothermic reaction is a reaction with release of heat. As an example the burning reaction of methane: CH4 + 2 O2 ------→ CO2 + 2 H2O
What happens to hydrochloric acid when it reacts to baking soda?
NaHCO3 + HCL = NaCL + H2O + CO2 The reaction is exothermic ie. it gives out heat during the process.
Is the breakdown of glucose endothermic or exothermic?
Exothermic. Glucose is one of the major source of energy of the body and can only act as an energy source because its breakdown into CO2 is an exothermic reaction.
What is the equation for an exothermic reaction?
In exothermic reactions heat is liberated. So reaction can be reactants---->products+heat
What is the reaction of sodium bicarbonate and hydrochloric acid is endothermic or exothermic?
Neutralisation reaction will take place. HCl + NaHCO3 ---> NaCl + H2O + CO2
Which equation represents an exothermic reaction at 298 K?
An exothermic reaction is one where heat is released to the surroundings. An example of an exothermic reaction equation at 298 K is: 2H2(g) + O2(g) -> 2H2O(l) + heat
Which compound is formed from its elements by an exothermic reaction at 298 K and 101.3 kPa?
Carbon dioxide (CO2) is formed from its elements (carbon and oxygen) by an exothermic reaction at 298 K and 101.3 kPa.
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.
Is Na2O plus CO2 exothermic or endothermic?
The reaction between sodium oxide (Na2O) and carbon dioxide (CO2) is generally exothermic. When Na2O reacts with CO2, it forms sodium carbonate (Na2CO3), releasing heat during the process. This exothermic nature is typical of reactions involving the formation of stable ionic compounds from simpler oxides and gases.
What happens to hydrochloric acid when it reacts with baking soda?
NaHCO3 + HCL = NaCL + H2O + CO2 The reaction is exothermic ie. it gives out heat during the process.
