The true value was 0.120. What was your percent error?

Answers

Answer 1

The question is incomplete as the measured value isn't given. However, an hypothesized measured value will be used to explain how to calculate the percentage error.

Answer:

2.5%

Explanation:

Percentage error :

[(measured value - True value)/ True value] * 100%

The measured value is the value obtained during an while using a measuring device.

If the measured value is = 0.123

Then, the percent error will be :

[(0.123 - 0.120) / 0.120] * 100%

(0.003 / 0.120) * 100%

0.025 * 100%

= 2.5%

Answer 2

The percent error is 2.5%. When the true value was 0.120.

Percent error is a measurement used to quantify the discrepancy between an estimated or experimental value and a known or accepted value.

Given information:

The measured value is 0.123

The true value is 0.120

Calculate the percent error using the formula given as below:

Percent Error = (|True Value - Measured Value| / True Value) * 100%

Substituting the given values in the above equation:

Percent Error = (|0.120 - 0.123| / 0.120) × 100%

= (0.003 / 0.120) × 100%

= 0.025 × 100%

= 2.5%

Therefore, the percent error is 2.5%.

Describe what is happening within the system when it is at equilibrium in terms of concentrations, reactions that occur, and reaction rates.

Answers

Answer:

Describe what is happening within the system when it is at equilibrium in terms of concentrations, reactions that occur, and reaction rates.

Explanation:

The chemical equilibrium state is the state where the rate of forward reaction becomes equal to the rate of backward reaction.

At this stage the change in concentration of reactants becomes equal to the change in concentration of products.

The reaction will never cease.

That is the reason chemical equilibrium is called dynamic equilibrium.

So, forward and backward reactions will be taking place continuously at equal rates.

why is the reaction of Iron and hydrochloric acid slow ​

Answers

Answer:

The chloride formed when iron reacts with hydrochloric acid is iron (II) chloride, also known as iron dichloride. The reaction between iron and hydrochloric acid is slower than the reaction with zinc, with much smaller hydrogen bubbles produced.

Answer:  

The reaction of iron and hydrochloric acid is slow beacause When dilute Hydrochloric acid is added to iron filings, iron(II) chloride & hydrogen gas is produced. In this reaction iron displaces hydrogen from hydrochloric acid to form iron chloride & hydrogen gas this reaction is a single displacement reaction which reacts slowly.

A 115.0-g sample of oxygen was produced by heating 400.0 g of potassium chlorate. 2KClO3 Right arrow. 2KCI 3O2 What is the percent yield of oxygen in this chemical reaction

Answers

Answer:

Percentage yield of O₂ = 73.4%

Explanation:

We'll begin by writing the balanced equation for the reaction. This is given below:

2KClO₃ —> 2KCl + 3O₂

Next, we shall determine the mass of KClO₃ that decomposed and the mass of O₂ produced from the balanced equation. This can be obtained as follow:

Molar mass of KClO₃ = 39 + 35.5 + (3×16)

= 39 + 35.5 + 48

= 122.5 g/mol

Mass of KClO₃ from the balanced equation = 2 × 122.5 = 245 g

Molar mass of O₂ = 2 × 16 = 32 g/mol

Mass of O₂ from the balanced equation = 3 × 32 = 96 g

SUMMARY:

From the balanced equation above,

245 g of KClO₃ decomposed to produce 96 g of O₂.

Next, we shall determine the theoretical yield of O₂. This can be obtained as follow:

From the balanced equation above,

245 g of KClO₃ decomposed to produce 96 g of O₂.

Therefore, 400 g 245 g of KClO₃ will decompose to produce

= (400 × 96)/245 = 156.7 g of O₂.

Thus, the theoretical yield of O₂ is 156.7 g

Finally, we shall determine the percentage yield of O₂. This can be obtained as follow:

Actual yield of O₂ = 115.0 g

Theoretical yield of O₂ = 156.7 g

Percentage yield of O₂ =?

Percentage yield = Actual yield /Theoretical × 100

Percentage yield = 115/156.7 × 100

Percentage yield = 11500/156.7

Percentage yield of O₂ = 73.4%

Mike watch 100 m north then watch 30 m south after this he walks another 10 m north what is the magnitude of his total displacement during this walk in meters

Answers

Answer:

His total displacement is 80 m northwards

Explanation:

Given;

Mike's first displacement, x₁ = 100 m North

Mike's second displacement, x₂ = 30 m South

Mike's third displacement, x₃ = 10 m North

Let his Northwards direction be positive, and

his Southwards direction be negative

His total displacement = (100 m North) + ( - 30 m South) + (10 m north)

                                     = (100 m + 10m - 30 m)

                                     = 80 m  Northwards

El suero fisiológico tiene una concentración de 8,78 gr/lt. Calcula la masa de NaCl que ingresa en el organismo de un paciente al que se le administra suero durante 4 hs con una velocidad de goteo de una gota por segundo (Volumen gota: 0,05 ml)

Answers

Un paciente que recibe suero fisiológico a una velocidad de infusión de 1 gota = 0,05 ml por segundo recibirá en 5 horas 790 grs de NaCl, tomando en cuenta que la solución acuosa de suero fisiológico contiene 0,878 grs/mL de NaCl.

Explicación

Los datos que se tienen son:

Concentración de NaCl 0,878 grs/mlVolumen de la gota: 0,05 ml/gotaVelocidad de infusión 1 gota/ seg = 60 gotas/ min = 3 ml/minTiempo de infusión = 5 horas = 300 minutos

Ya establecidas las respectivas conversiones se trata de determinar qué volumen de suero fisiológivo se ha infundido al paciente en 5 horas

Si se infunden 3 ml cada minuto, ¿Cuánto se habrá infundido en 300 minutos?

3 ml ______________ 1 min

X ________________ 300 min

X = (300 min x 3 ml) / 1 min

X = 900 ml

Como en 5 horas el paciente ha recibido 900 ml de suero, se determina la cantidad de NaCl que se encuentra en ese volumen de líquido

0,878 grs __________ 1 ml

X ________________ 900 ml

X = (900 ml x 0,878 grs) / 1 ml

X = 790 grs de NaCl
