You must first convert kJ/mol.
So..
-237kJ x (1kJ / 2.60mol) = -91.15kJ
You then must take this and multiple by (-1),
since you cannot have a negative heat.
(-91.15kJ x -1) =
91.15kJ
Formation of wolfram disilicide, WSi2.
Acetic acid when reacts with an alcohol forms an ester, CH3COOH + C2H5OH = CH3COOC2H5 + H2O
Al2Br6 reacts vigorously with water with evolution of HBr and formation of Al-OH-Br species.
1. Cannizaro's reaction of HCNO with NaOH 2HCHO + NaOH → CH3OH + HCOONa 2. formation of useful resins when HCHO reacts with certain compounds HCHO + casein -------karolith HCNO + phenol ------- bakelite 3. formation of formose, in sweet lasing syrup and a mixture of sugars, when HCNO reacts with calcium hydroxide 6HCNO → C6H12O6 4. HCNO reacts with ammonia to give hexamethylenetetramine
chemical, specifically an "oxidation" reaction (even though oxygen is not involved).

chlorophyll in the chloroplasts
Formation of wolfram disilicide, WSi2.
Chemical change happens when there is an acid formation as the substances and chemicals reacts to form new substances.
Unknown today, probably the formation of an alloy.
The hydroniumion is absorbed by a base in water. It reacts in a neutralization reaction with something acidic, generally referred to as an H+ ion.
yes, with the formation of zinc chloride - ZnCl2.
Not known today but very probable the formation of an oxide.

Acetic acid when reacts with an alcohol forms an ester, CH3COOH + C2H5OH = CH3COOC2H5 + H2O
A formation equation is something like this: H2 + 0.5O2 --> H20. Formation equations are the only case in which a formula can have fractions, this is because the product must have one mol of the compound. In the case of Ammonia:Hydrogen reacts with Nitrogen to form Ammonia:H2 + N2 --> NH3 [incorrect]3/2 H2 + 1/2 N2 --> NH3 [correct]That is the equation for the formation of Ammonia
