Calculate the ph of the solution that results following addition of 24 ml of 1.0 mnaoh to 60 ml of 1.0 mnh4cl.
Lostsunrise [7]

The pH of the solution is 0.37.

<h3>What is the pH of the solution?</h3>

We can write the equation of the reaction as;

NH4Cl (aq) + NaOH (aq) ------- > NH3 (aq) + H2O (l) + NaCl (aq)

Number of moles of NaOH= 24/1000 * 1 = 0.024 moles

Number of moles of NH4Cl= 60/1000 * 1  = 0.060 moles

Given that the reaction is 1:1, the limiting reactant is NaOH

Number of moles of NH4Cl left over = 0.060 - 0.024 = 0.036 moles

Concentration of left  over NH4Cl = 0.036 moles/(24 + 60)/1000

= 0.43 moles

pH = -log(0.43)

pH = 0.37

Pedro quiere mover una roca de 300N con una palanca y se coloca a 1.5 m del fulcro, la distancia de la roca al fulcro es de 30 c
insens350 [35]

Answer:

- The necessary formula to find the force that Pedro must apply is

(Load) × (distance of Load from the fulcrum) = (Effort) × (distance of Edfort from the fulcrum)

- The force that Pedro must apply = 60 N

- La fórmula necesaria para encontrar la fuerza que Pedro debe aplicar es

(Carga) × (distancia de carga desde el punto de apoyo) = (esfuerzo) × (distancia de Edfort desde el punto de apoyo)

- La fuerza que debe aplicar Pedro = 60 N

Explanation:

English Translation

Pedro wants to move a 300N rock with a lever and it is placed 1.5 m from the fulcrum, the distance from the rock to the fulcrum is 30 cm. Select the necessary formula to find the force that Pedro must apply

Solution

The sum of clockwise moment must balance the sum of anti-clockwise moment.

Let the force that Pedro must apply = Effort = F

Taking moment about the fulcrum

(Load) × (distance of load from the fulcrum) = (Effort) × (distance of Edfort from the fulcrum)

Load = 300 N

Distance of Load from the fulcrum = 30 cm = 0.30 m

Effort = F

Distance of Effort from the fulcrum = 1.5 m

300 × 0.30 = F × 1.5

F = (300×0.30)/1.5 = 60 N

In Spanish/En español

La suma del momento en sentido horario debe equilibrar la suma del momento en sentido antihorario.

Deje que la fuerza que Pedro debe aplicar = esfuerzo = F

Tomando un momento sobre el fulcro

(Carga) × (distancia de carga desde el punto de apoyo) = (esfuerzo) × (distancia de Edfort desde el punto de apoyo)

Carga = 300 N

Distancia de carga desde el fulcro = 30 cm = 0.30 m

Esfuerzo = F

Distancia de esfuerzo desde el punto de apoyo = 1.5 m

300 × 0.30 = F × 1.5

F = (300×0.30)/1.5 = 60 N

Hope this Helps!!!
