Is the Haber process reaction endothermic or exothermic?
Exothermic! Gosh. I had to change two answers which said "Endothermic" <object width="320" height="30"> <param value="http://images.mp3raid.com/i/mp3player.swf" name="movie" />
How do you know that given chemical equation is exothermic or endothermic?
Chemical reactions are about making and breaking bonds. You have to add up how much energy is used to break the chemical bonds of the reactants, and subtract this from the total amount of energy used to make the bonds of the product(s). To do this, you need to know how much energy is needed to make/break each bond. Here are some examples: C-H 98 O-H 110 C-C 80 C-O 78 H-H 103 C-N 65 O=O 116(2 x 58) C=O 187(2 x 93.5) C=C 145 (2 x 72.5) These are all in kcal/mole. When you've worked this out, if the end number is negative then the reaction is exothermic, if the answer's positive, then it's endothermic. Alternatively you could just try the experiment yourself.
What is the reaction of ethanoic acid and ethylamine?
The reaction between ethanoic acid and ethylamine forms the salt known as ethylammonium ethanoate, along with water as a byproduct. This reaction is an example of a neutralization reaction, where the acid and base react to form a salt.
Will sulfuric acid react to strip-n-all?
Yes, sulfuric acid is a strong acid that can react with strip-n-all, which is a paint stripper. This reaction is exothermic and can release harmful fumes, so it should be handled with caution in a well-ventilated area. It's advised to always read and follow the safety instructions provided by the manufacturer of both products.
How do you prepare 10 N of NAOH?
To prepare a 10 N solution of NaOH, you would dissolve 400 g of NaOH pellets in enough distilled water to make 1 liter of solution. Remember to add the NaOH to the water slowly and carefully due to the exothermic nature of the reaction. Finally, stir the solution until all of the NaOH has fully dissolved.

What happens to the reaction 2 N O 2 in equilibrium with N 2 O 4 plus 57.3 kilojoules when the temperature of the reaction is increased?
This is an endothermic equilibrium reaction Thus, increase temperature will push the reaction to the right. So more N2O4 is produced
What are some non- examples of endothermic process?
You are given the following chemical rection N 2 ( g ) O 2 ( g ) → 2 N O ( g ) Provide an explanaition for why this reaction is endothermic (both conceptual, and mathematical); Is this reaction spontaneous at 298 K? If not, at what temperature does it become spontaneous? Data given: Δ H ∘ f = 90.4 kJ/mol for N O and Δ S reaction = 24.7 J/K Let's start with the math to get it out of the way. A reaction is said to be endothermic if its change in enthalpy, Δ H reaction , is positive. We can calculate this change in enthalpy from what the data provides us. Δ H reaction = 2 moles NO ⋅ 90.4 k J m o l − ( 1 mole N 2 ) ⋅ 0 k J m o l − ( 1 mole O 2 ) ⋅ 0 k J m o l Δ H reaction = 2 moles NO ⋅ 90.4 k J m o l = 180.8 k J The trick here was to be aware of the fact that the enthalpy of formation ( Δ H ∘ f ) for elements is zero. Since Δ H reaction > 0 , the reaction is indeed endothermic. Conceptually, this reaction is endothermic despite the fact that a bond (between N and O ) is formed; this happens because the N 2 molecule has its two atoms bonded together by a very strong triple bond, which means that more energy must be put into breaking this bond than is released when the N O molecule is formed. Now, in order for a reaction to be spontaneous, the sign of Δ G the Gibbs free energy - must be negative at the given temperature. We can therefore determine this reaction's spontaneity by using Δ G reaction = Δ H reaction − T ⋅ Δ S reaction Δ G reaction = 180.8 ⋅ 10 3 J − 298 K ⋅ 24.71 ⋅ J K = 173.4 k J The reaction is not spontaneous at this temperature. We can determine at what temperature the reaction starts to be spontaneous by setting Δ G reaction = 0 . 0 = Δ H reaction − T ⋅ Δ S reaction T = Δ H reaction Δ S reaction = 180.8 ⋅ 10 3 J 24.71 J K = 7317 K This reaction becomes spontaneous at 7317 K . As a conclusion, questions about endothermic or exothermic processes revolve around Δ H , Δ S , and Δ G if a reaction's spontaneity is in question.

What happens in sodium metal in water?
When sodium metal is put in water, it reacts vigorously to produce sodium hydroxide and hydrogen gas. The reaction is highly exothermic, releasing a lot of heat. If done in large quantities or improperly, it can lead to a violent explosion due to the rapid release of hydrogen gas.
What reaction is magnesium with N?
Magnesium does not react with nitrogen under normal conditions. However, at high temperatures, magnesium can form magnesium nitride (Mg3N2) by reacting directly with nitrogen gas. This reaction is highly endothermic and requires extreme conditions to proceed.
Formula for a neutralisation reaction?
neutralisation reaction: n=vm2 + charlotte
How do you quench n- butyl lithium?
n-Butyl lithium is typically quenched with alcohols, such as methanol or ethanol, or with weak acids, such as ammonium chloride. The quenching reaction neutralizes the active lithium species, preventing any further reactions. It is important to handle the quenching step carefully to avoid rapid exothermic reactions.
What happens when you mix water and sulphuric acid?
when we add water n sulphuric acid then dilute sulphuric acid is formed. But we have to mix concentrated acid to water not water to acid otherwise the container in which u r mixing may explode because this reaction is highly exothermic.
What is the chemical reaction for hydrogenation?
---(CH=CH)n-- + n H2 -------> (-CH2-CH2-)n
