Qui manquent dans le bécher du premier dessin. Exercice 4 : Dans une pile à hydrogène (pour faire fonctionner une voiture à hydrogène), c'est la combustion du
dihydrogène qui permet de produire l'électricité
Le dihydrogène réagit avec le dioxygène de l'air pour former de l'eau, de la chaleur et de l'électricité.
a) Quels sont les réactifs nécessaire au fonctionnement d'une voiture à hydrogène ?
b) Quel est le produit généré ?
d) La masse du produit est-elle égale à la somme des masses des 2 réactifs ?
c) Écris l'équation de la réaction (en l'équilibrant).

You mix the pks of succinic acid are 4.21 and 5.64. how many gramsa graduate student at sdsu wants to measure the activity of a particular enzyme at ph 4.0. to buffer her reaction, she will use a buffer system based on one of the acids listed below, which acid is most appropriate for the experiment? of monosodium succinate (fw = 140 g/mol) and disodium succinate (fw = 162 g/mol) must be added to 1 l of water to produce a solution with a ph 5.28 and a total solute concentration of 100 mm? (assume the total volume remains 1 liter, answer in grams monosodium succinate, grams disodium succinate, respectively.) volumes of 0.05 m nah2po4 and 0.05 m na2hpo4 (pk's for phosphoric acid are 2.15, 6.82 and 12.38). which of the following best describes the resulting solution?
