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.

Answer:
Newtons first law
Explanation:
Objects stay at rest until a force acts on it causing it to move from its resting position
Answer:
The slowdown took 2.05 seconds and the roller coaster made a distance 20.5 during that time.
Explanation:
Start with the kinematic equation for velocity. Let v1 and v2 be the initial and the new velocity, respectively. Let s denote the distance made duringthe slowdown. Let m denote the mass of the roller coaster and "a" its acceleration (negative = deceleration). the equation is as follows:
Let us first determine the distance made:
The roller coaster made 20.5 meters during slowing down to 2 m/s. Now calculate the time this took.
It took 2.05 seconds to achieve the slowdown from 18 to 2 m/s
Answer:
Distancia = 17,5 kilómetros.
Explanation:
Dados los siguientes datos;
Velocidad = 36 km/h
Tiempo = 0.5 horas
Para encontrar la distancia recorrida;
Distancia = velocidad * tiempo
Distancia = 35 * 0.5
Distancia = 17,5 kilómetros.
Por tanto, la distancia recorrida por el automóvil es de 17,5 kilómetros.
The de - acceleration of bullet from 360 m/s after it struck the tree trunk and was brought to rest is -152.54 x 10⁴ m/s².
<h3>What is Acceleration in Kinematics?</h3>
Acceleration is defined as the rate of change of velocity with respect to time. Mathematically -
<h3>a = Δv/Δt</h3>
Given is a bullet initially travelling at 360 m/s struck into a tree trunk 8.5 cm inside and comes to rest. From this, we can write
initial velocity [u] = 360 m/s
final velocity [v] = 0 m/s
distance travelled [d] = 8.5 cm = 0.085 m
The time span after which bullet comes to rest will be -
Δt = d/u
Δt = 0.085/360 = 2.36 x 10 ⁻⁴ seconds
a = Δv/Δt
Δv = 0 - 360 = - 360 m/s
a = (v - u)/Δt
a = - 360/(2.36 x 10 ⁻⁴)
a = - 152.54 x 10⁴ m/s²
Therefore, the de - acceleration of bullet from 360 m/s after it struck the tree trunk and was brought to rest is -152.54 x 10⁴ m/s².
