7-¿Cuántos moles de CO2 estarán encerrados en un recipiente metálico a una presión de 1.10 Atm. y una temperatura de 31 °C, sabi
Aleks [24]

Answer:

7- 0.69 moles.

8- El nuevo volumen es 3.8L.

Explanation:

7- Usando la ley general de los gases:

PV = nRT

PV / RT = n

<em>P es presión = 1.10atm</em>

<em>V es volumen = 15.70L</em>

<em>R es constante de los gases = 0.082atmL/molK</em>

<em>T es temperatura absoluta = 31°C + 273.15K = 304.15K</em>

<em />

Reemplazando:

1.10atm*15.70L / 0.082atmL/molK*304.15K = n

<h3>0.69 moles</h3><h3 />

8- La ley combinada de los gases establece como ecuación:

P1V1 / T1 = P2V2 / T2

<em>Donde P1 es la presión inicial = 760mmHg</em>

<em>V1 volumen inicial = 2L</em>

<em>T1 es temperatura absoluta = 273.15 + 27 = 300.15K</em>

<em>P2 = 380mmHg</em>

<em>T2 = 12°C + 273.15 = 285.15K</em>

<em />

Reemplazando:

760mmHg*2L / 300.15K = 380mmHg*V2 / 285.15K

3.8L = V2

<h3>El nuevo volumen es 3.8L</h3>

STatiana [176]
Na2C2O4(aq) + CaCl2(aq) -----> 2NaCl(aq) + CaC2O4(s)

Here, CaC2O4(s) is a precipitate in the reaction as a result of precipitation reaction or double displacement reaction.

As we know that double displacement reaction two metal ions displaces each other from their salt solutions.

As we know that precipitation reaction is a reaction in which precipitate is formed.

explain how one and two letters chemical symbols are used to identify elements whose names begin with the same letter, for examp
Nadusha1986 [10]

The symbol of helium is He and this distinguishes it from the symbol for hydrogen.

<h3>What are chemical symbols?</h3>

Chemical symbol are the means by which we designate elements on paper. The symbols could be one letter or two letter as the case may be. There is no chemical symbol that has more than two letters that are used to designate the element.

We know that hydrogen has the symbol H. There is to way that another element will also have the symbol H as that would be tantamount to confusion. As a result of that, the symbol of helium is He and this distinguishes it from the symbol for hydrogen.
