Si en un planeta la presión atmosférica es mayor que 5,1 atm terrestres, los habitantes podrían nadar en ríos de dióxido de carb
Sphinxa [80]

Answer:

Los habitantes del planeta con una atmósfera superior a 5,1 atm de la Tierra, no estarían nadando en ríos de dióxido de carbono líquido

Explanation:

De las tablas de datos termodinámicos, la presión a la que el vapor de dióxido de carbono está en equilibrio con su estado líquido a una temperatura ambiente de 25 ° C es 6,401 kPa, lo que equivale a 63,17296 atm.

Por lo tanto, a una presión de 5.1 de la atmósfera terrestre, el dióxido de carbono es completamente gaseoso y los habitantes del planeta con una presión atmosférica de 5.1 atm de la Tierra todavía observarían solo hidrógeno gaseoso y no estarían nadando en ríos de dióxido de carbono líquido.

If 0.500 mole of calcium carbonate is produced in a particular reaction, how many moles of sodium chloride are produced in the s
blsea [12.9K]

Answer: 1mole of NaCl

Explanation:

Looking at the given equation :CaCl2 (aq) + Na2CO3 (aq) → CaCO3 (s) + 2 NaCl (aq)

The following deductions can be made,

1 mole of CaCl2 reacted with 1 mole of Na2CO3 to produce 1mole of CaCO3 and 2NaCl.

If 0.500 mole of CaCO3 was produced from this same reaction,it therefore means that we multiply the coefficients of both reactants and product by 0.500 to know the moles of NaCl that will also come out from this same reaction..

So we have the new equation to be:

0.5CaCl2 (aq) + 0.5 Na2CO3 (aq) → 0.5 CaCO3 (s) + 1 NaCl (aq)

From the new equation,1mole of NaCl will be produce alongside 0.5mole of CaCO3,when 0.5mole of CaCl2 reacts with.0.5mole Na2CO3.
