Answer: 0.119 mole of Kr has a mass of 10.0 g

Explanation:

The complete Question was ontained online, albeit, it was incomplete, even from the online source. But the solution is possible based on the part of the question obtained.

Complete Question

Which of the following Noble Gases has a mass of 10.0 g?

A. 2.02 mol Ne B. 0.119 mol Kr C.

Solution

Number of moles = (Mass)/(Molar Mass)

Mass = (Number of moles) × (Molar mass)

Checking the options, one at a time,

A. 2.02 moles of Neon

Number of moles = 2.02 moles

Molar Mass of Neon = 20.1797 g/mol

Mass = 2.02 × 20.1797 = 40.762994 g ≠ 10.0 g

Not the answer.

B. 0.119 moles of Krypton

Number of moles = 0.119 moles

Molar Mass of Krypton = 83.798 g/mol

Mass = 0.119 × 83.798 = 9.971962 g ≈ 10.

Answer:

75 g/dm³

Explanation:

The following data were obtained from the question:

Mass of solute (NaCl) = 15 g

Volume of solution = 200 cm³

Concentration (in g/dm³) =?

Next, we shall convert 200 cm³ to dm³. This can be obtained as follow:

1000 cm³ = 1 dm³

Therefore,

200 cm³ = 200 cm³ × 1 dm³ / 1000 cm³

200 cm³ = 0.2 dm³

Thus, 200 cm³ is equivalent to 0.2 dm³.

Finally, we shall determine the concentration of the solution as follow:

Mass of solute (NaCl) = 15 g

Volume of solution = 0.2 dm³

Concentration (in g/dm³) =?

Concentration (in g/dm³) = mass / volume

Concentration (in g/dm³) = 15 g /0.2 dm³

Concentration (in g/dm³) = 75 g/dm³

Answer:

La distancia recorrida por el móvil es 228.600 m

Explanation:

El movimiento rectilíneo uniforme MRU es el movimiento que describe un cuerpo o partícula a través de una línea recta a velocidad constante. Es decir:, en este caso el movimiento es lineal en una única dirección  y la velocidad de desplazamiento es constante.

La velocidad es una magnitud física que expresa la relación entre el espacio recorrido por un objeto y el tiempo empleado para ello mediante la expresión:

[tex]velocidad=\frac{distancia}{tiempo}[/tex]

En este caso:

Reemplazando:

[tex]25 \frac{m}{s} =\frac{distancia}{9144 s}[/tex]

y resolviendo obtienes:

distancia= 25[tex]\frac{m}{s}[/tex] *9144 s

distancia= 228.600 m

La distancia recorrida por el móvil es 228.600 m

A movement is rectilinear uniform when an "object" (for example) travels in a straight path at a constant speed, given that its acceleration is zero.

Velocity (v) = 25m/s

Distance (d) = ?

Time (t) = 2.54hr = 9,144 s

Looking at the data, we see that the time is in hr, but we need it in seconds. Therefore we do a conversion from hours to minutes, taking into account that 1 hour is equal to 3600 seconds.

To calculate the distance traveled by the mobile, the speed is multiplied by the time taken.

For this the following formula is applied:

We apply the data in the formula; to solve for the distance.

Answer: The distance traveled by the mobile is 228,600 meters.

Answer:

Multicellular

Explanation:

Prokaryotic cells are unicellular because the do not have a nucleus and lack organelles, while eukaryotic cells do have a nucleus, have organelles, and are are multicellular. :)

Organisms that are made up of prokaryotic cells are NOT

Multicellular.

Living organisms can be classified based on their cellular organisation.

Organisms that are made up of one cell are known as unicellular organisms.

Organisms that are made up of more than one cell are known as multicellular organisms.

A prokaryote is an organism that lacks distinct nucleus while eukaryote is an organism that possess a nucleus that is enclosed in a nuclear envelope.

While prokaryotes are always unicellular organisms, eukaryotes can be either unicellular or multicellular.

Therefore, organisms that are made up of prokaryotic cells are not multicellular.

Answer:

Liquids have characteristic properties based on the molecules they are made of. Liquids can dissolve certain other liquids, depending on the attractions between the molecules of both liquids. Polar liquids, like water, dissolve other liquids which are polar or somewhat polar.

Explanation:

Positron emission gives a new nucleus with the same mass number but an atomic number that is one less than the old one. Electron emission gives an atomic number that is one greater. Both positrons and electrons are β particles. A positron is the antimatter counterpart of an electron

Answer:

V = 0.25 x 22.4 Liters

Explanation:

1 mole of any gas occupies 22.4 Liters at STP.

Taking into account the STP conditions, the volume occupied by 0.25 mol of sulfur dioxide at STP is 5.6 L.

First of all, STP conditions is the abbreviation for Standard Temperature and Pressure. The standard temperature is 273 K (0 ° Celsius or 32 ° Fahrenheit) and the standard pressure is 1 atm of pressure and are reference values for gases. And in these conditions 1 mole of any gas occupies an approximate volume of 22.4 liters.

On the other hand, the rule of three is a tool that allows you to quickly solve proportionality problems.

To apply a rule of three, 3 pieces of information are needed, from which a fourth piece of information is calculated.

If the relationship between the magnitudes is direct, the rule of three must be applied. In this case, the following formula must be followed, knowing a, b and c and where x is the value to be calculated:

In this case, the rule of three is applied as follows: if by STP conditions, 1 mole of the gas occupies 22.4 L, 0.25 mole will occupy how much volume?

[tex]volume=\frac{0.25 moles*22.4 L}{1 mole}[/tex]

Solving:

volume= 5.6 L

In summary, the volume occupied by 0.25 mol of sulfur dioxide at STP is 5.6 L.

SnO2

Explanation:

The limiting reactant is the reactant that runs out first during a chemical reaction.

Reactants are on the left side of the reaction, so SnO2 and H2. They tell us in the question that there is "excess" hydrogen (H2), so we know there is plenty of it, as "excess" means "more than enough." If we have more than enough hydrogen, then we know that we will run out of SnO2 first.

Answer:

9302 moles of CO contain 5.60×10²⁷ molecules

Explanation:

We solve this with Avogadro's number.

NA = 6.02×10²³

This number states the how many particles are in 1 mol of anything.

1 mol of atoms contains 6.02×10²³ atoms

1 mol of molecules  contains 6.02×10²³ molecules.

We apply a rule of three:

6.02×10²³ molecules are contained in 1 mol of CO

Then, 5.60×10²⁷ molecules may be contained in (5.60×10²⁷ . 1) / 6.02×10²³

= 9302 moles

Answer:

The pH of the buffer is 7.0 and this pH is not useful to pH 7.0

Explanation:

The pH of a buffer is obtained by using H-H equation:

pH = pKa + log [A⁻] / [HA]

Where pH is the pH of the buffer

The pKa of acetic acid is 4.74.

[A⁻] could be taken as moles of sodium acetate (14.59g * (1mol / 82g) = 0.1779 moles

[HA] are the moles of acetic acid (0.060g * (1mol / 60g) = 0.001moles

Replacing:

pH = 4.74 + log [0.1779mol] / [0.001mol]

pH = 6.99 ≈ 7.0

The pH of the buffer is 7.0

But the buffer is not useful to pH = 7.0 because a buffer works between pKa±1 (For acetic acid: 3.74 - 5.74). As pH 7.0 is out of this interval,

this pH is not useful to pH 7.0

Explanation:

Hydrophosphoric acid, H₃P = Phosphine has a density of 1.38g/L.

To solve this question we need to convert the volume of the gas to mass in grams as first and then to kilograms as follows:

Mass in grams:

25L * (1.38g / L) = 34.5g

Mass in kilograms:

34.5g * (1kg / 1000g) = 0.0345kg is the mass of 25L of the sample
