Answer:
Se obtienen 2,27 gramos de metanol.
Explanation:
La reacción entre monóxido de carbono e hidrógeno para producir metanol es la siguiente:
CO + 2H₂ → CH₃OH
Para encontrar el reactivo limitante y el reactivo en exceso, debemos calcular el número de moles de CO y H₂:
En donde:
m: es la masa
M: es el peso molecular
Dado que la relación estequiométrica entre CO y H₂ es 1:2, el número de moles de hidrógeno gaseoso que reaccionan con el monóxido de carbono es:
Entonces, se necesitan 0,142 moles de H₂ para reaccionar con 0,071 moles de CO y debido a que se tienen más moles de H₂ (0,99 moles) entonces el reactivo limitante es CO y el reactivo en exceso es H₂.
Ahora podemos encontar la masa de metanol obtenida usando el reactivo limitante (CO) y sabiendo que la realcion estequiométrica entre CO y CH₃OH es 1:1.
Por lo tanto, se obtienen 2,27 gramos de metanol.

It is easy to see the think layers in the stone. Metamorphic rock often forms layers due to being squeezed under pressure. Since it separates into think sheets,slate has been used for chalkboards roof,shingles,and pool table tops.
Clouds form when water vapor in the air condenses into visible water droplets or ice crystals
Answer:
The center of the Milky Way most likely contains a supermassive black hole.
Explanation:
Because it is an eleptical galaxy, it has a little rotation to it but not enough to flatten out so the center will contain a supermassive black hole.
Answer:
correct answers will be
2. The train is not an inertial frame of reference.
5.The train may be moving at a constant speed in a circle.
8. The train must be accelerating.
Explanation:
As we know that string makes an angle with the horizontal
so we can write the force equation for the given ball
also in Y direction
now we have
now we can conclude that train is accelerating with acceleration same as gravity
now correct answers will be
2. The train is not an inertial frame of reference.
5.The train may be moving at a constant speed in a circle.
8. The train must be accelerating.
