UNO [17]3 years ago
6 0

Answer:

12.4g of water has 0.689 moles of water.

Explanation:

Molar weight of H_{2}O = 16 + 2 = 18g

One mole of H_{2}O weighs 18g.

18g\longrightarrow1\:mole\:of\:H_{2}O\\12.4g\longrightarrow\frac{12.4}{18}=0.689\:moles\:of\:H_{2}O

Hence, 12.4g of water has 0.689 moles of water.

Ricardo compra un gaseosa en el súper al destaparla la gaseosa comienza a salir espuma y vuelca la mitad al piso ¿Por qué puede
dimaraw [331]

Answer:

Las bebidas gaseosas como las gaseosas están hechas de un soluto de dióxido de carbono gaseoso en un líquido. La solubilidad del dióxido de carbono en el líquido depende de la presión y la temperatura de la lata de refresco, y también de agitar la lata de refresco que introduce burbujas que permanecen ocultas hasta que se abre la lata antes de que burbujee.

Por lo tanto, dado que la presión en la lata de refresco permanece constante, elevar la temperatura, agitar la lata de refresco o congelar el refresco, lo que aumenta la cantidad de dióxido de carbono en la porción líquida, hará que el refresco forme espuma y se derrame.

lara [203]

Answer:

Precipitation

Explanation:

Let's consider the balanced chemical equation between barium acetate and sodium carbonate to form barium carbonate and sodium acetate.

Ba(C₂H₃O₂)₂(aq) + Na₂CO₃(aq) → BaCO₃(s) + 2 NaC₂H₃O₂(aq)

Both products and reactants are salts. But, among the products, barium carbonate is solid. This allows us to classify it as a precipitation reaction.
