Three reasons for air is mixture and water is compound

zhannawk [14.2K]

1. air components change from place to place, while water will just stay the same

2. Water doesn't have nor show individual properties, but air does show that it has it's own property

3. You can separate different gases from air physically, but with water you must pass electricity through it.

Don't take my word for it, this is just what I learned back in middle school.

Un gas ocupa 24,6 litros a 27°C y 10 moles, que presión posee. R=0.082

Anastasy [175]

Answer:

$P=10 atm$

Explanation:

Hola,

En este caso, usando la ecuación del gas ideal, podemos calcular facilmente la presión a partir de:

$PV=nRT$

Por lo que despejando para la presión obtenemos:

$P=\frac{nRT}{V}$

Así, calculamos:

$P=\frac{10mol*0.082\frac{atm*L}{mol*K}*(27+273)K}{24.6L} \\\\P=10 atm$

¡Saludos!

Determine the mass in grams of 4.69 x 1021 atoms of barium. (The

Virty [35]

Answer:

1.07 g Ba

Explanation:

Hello there!

In this case, according to the definition of the Avogadro's number and the molar mass, it is possible to say that 6.022x10^{23} atoms of barium equal one mole, and at the same time, 1 mole equals 137.327 grams of this element; thus, it is possible to say that 6.022x10^{23} atoms of barium have a mass of 137.327 grams; therefore, it i possible for us to calculate the required mass in grams as shown below:

$4.69x10^{21}atoms*\frac{137.327gBa}{6.022x10^{23} atoms} \\\\=1.07gBa$

Best regards!
