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.

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%

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:

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

Answer:

SLS functions in cleaning product as a surfactant, wetting surfaces, emulsifying or solubilizing oils, and suspending soil so that they can be rinsed away. This ingredient contributes foaming properties to cleaning products. SLS is safe for use in cleaning products.

Sodium lauryl sulfate and ammonium lauryl sulfate are surfactants that help with the mixing of oil and water. As such, they can clean the skin and hair by helping water to mix with oil and dirt so that they can be rinsed away or suspend poorly soluble ingredients in water.

The U.S. Food and Drug Administration (FDA) includes sodium lauryl sulfate on its list of multipurpose additives allowed to be directly added to food. Sodium lauryl sulfate and ammonium lauryl sulfate are also approved indirect food additives. For example, both ingredients are permitted to be used as components of coatings.

The safety of sodium lauryl sulfate and ammonium lauryl sulfate has been assessed by the Cosmetic Ingredient Review  (CIR) Expert Panel on two separate occasions (1983 and 2002), concluding each time that the data showed these ingredients were safe in formulations designed for brief, discontinuous use, followed by thorough rinsing from the surface of the skin. In products intended for prolonged contact with skin, concentrations should not exceed 1%.  

Sodium lauryl sulfate and ammonium lauryl sulfate may be used in cosmetics and personal care products marketed in Europe according to the general provisions of the Cosmetics Regulation of the European Union.

Answer:

The higher its electronegativity, the more an element attracts electrons.

Explanation:

Electronegativity is a property that describes the tendency of an atom to attract electrons (or electron density) toward itself. An atom's electronegativity is affected by both its atomic number and the size of the atom.

Answer:

3.0 mol H₂O

Explanation:

Step 1: Write the balanced combustion equation

C₂H₆ + 3.5 O₂ ⇒ 2 CO₂ + 3 H₂O

Step 2: Establish the appropriate molar ratio

The molar ratio of C₂H₆ to H₂O is 1:3.

Step 3: Calculate the moles of H₂O formed from 1.0 mole of C₂H₆

1.0 mol C₂H₆ × 3 mol H₂O/1 mol C₂H₆ = 3.0 mol H₂O

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

The number of moles of oxygen in 1.60 moles of sodium hydrogen phosphate is 6.4 moles

Let's represent the chemical formula of the compound. The chemical formula of sodium hydrogen phosphate is as follows:

The chemical formula of a compound is a symbolic expression use to signify the number of atoms present in a molecular substance. Therefore,

sodium hydrogen phosphate  = Na₃PO₄

Therefore,

1 mole of Na₃PO₄ = 4 moles of oxygen

1.60 moles of Na₃PO₄  = ? moles of oxygen

cross multiply

number of moles of oxygen = 1.60 × 4

number of moles of oxygen = 6.4 moles

Answer:

The magnetic field of an atom, say H (one electron revolving around a proton) is composed of two separate contributions: an orbital magnetic moment and a spin magnetic moment. We get magnetic moments because of electromagnetic induction associated with each type of electron motion. The electron revolving around the proton with a certain angular momentum is related to the associated orbital magnetic moment (and, yes, we model it as a wire loop with current expressed in terms of the orbital velocity). This can be calculated using elementary mechanics. The spin magnetic moment is a little trickier because it is caused by the intrinsic spin of the electron which is a quantum phenomenon; therefore, this spin magnetic moment can only be calculated using quantum mechanics. In the end, we get a certain net magnetic moment associated with this motion of the electron in an atom. It is important to notice that this atom acts as a magnetic dipole (remember, as of yet, magnetic monopoles don't exist!).

If we take a bulk magnet like you might have on your fridge, it would be composed of atoms. Each atom operates as a magnetic dipole, but due to internal atomic structures, the atoms actually align themselves into separate magnetic domains, each with a net magnetic moment (caused my individually adding up those atomic dipole moments). In a common magnet (ferromagnet), these domains all point the same direction and stay that way, creating a permanent bulk magnetic dipole.

So in a way, there is no difference between the magnetic field of an atom and that of a magnet because one is simply a sum of the other, making both magnetic dipoles. Of course, here we see that there's nothing that fundamental about the magnetic force. In reality, the magnetic force is a relativistic effect caused by the movement of a charged particle, making electricity (i.e. charge) the underlying property at work here. Electromagnetic induction is really a shortcut to understand the magnetic force without worrying about relativistic mechanics. If we were to discover magnetic monopoles (i.e. "magnetic" charge), this would re-write a lot that we know about electromagnetism because we couldn't label all magnetic forces as by-products of moving electric charge
