Answer:

7.4 moles solute

Explanation:

From definition of Molarity (M) = moles solute (n)/volume of solution in Liters(V)

=> moles solute (n) = Molarity (M) x Volume (L) = (3.7 moles/L)(0.500L) = 7.4 moles solute

Answer:

[tex]V_2=18.0L[/tex]

Explanation:

Hello there!

In this case, according to the given information, we infer that we need the combined gas law in order to solve this problem:

[tex]\frac{P_2V_2}{T_2}} =\frac{P_1V_1}{T_1}}[/tex]

Thus, by suing the temperatures in Kelvins, we can solve for the final volume as shown below:

[tex]V_2 =\frac{P_1V_1T_2}{T_1P_2}}\\\\V_2 =\frac{(760mmHg)(22.4L)(232K)}{(273K)(805mmHg)} \\\\V_2=18.0L[/tex]

Answer: The order of being able to carry the MOST electric

current to the LEAST is Conductor, resistor, insulator

Explanation:

Resistor is a device which partially prevents the flow of electric current through it.

Insulator is a device which completely prevents the flow of electric current through it.

Conductor is a device which allows the flow of electric current through it.

Thus the sequence of words in order of being able to carry the MOST electric

current to the LEAST is Conductor , Resistor , Insulator.

Answer:

(β-decay) is a type of radioactive decay in which a beta particle (fast energetic electron or positron) is emitted from an atomic nucleus, transforming the original nuclide to an isobar of that nuclide. For example, beta decay of a neutron transforms it into a proton by the emission of an electron accompanied by an antineutrino; or, conversely a proton is converted into a neutron by the emission of a positron with a neutrino in so-called positron emission.

Explanation:

Answer:

Beta decay occurs when, in a nucleus with too many protons or too many neutrons, one of the protons or neutrons is transformed into the other. ... In beta plus decay, a proton decays into a neutron, a positron, and a neutrino: p Æ n + e+ +n.

Answer:

The melting point is the temperature at which a solid changes into a liquid. The melting point of a solid is the same as the freezing point of the liquid. At that temperature, the solid and liquid states of the substance are in equilibrium. For water, this equilibrium occurs at 0°C.

Explanation:

Answer:  Heat or pressure causes the phase change from solid ice to liquid water.

We are given:

V₁ = 400 mL               T₁ = 75°c = (273+75)K = 348K

V₂ = x mL                    T₂ = 95°c = (273+95)K = 368K

Deriving Boyle's Law:

here, we can see that the volume and temperature are the only variables

from the ideal gas equation:

PV = nRT

T /V = P / nR

because P, n and R are constants, P/nR is a constant value

T / V = constant

which means that the initial and final ratio of P and T will be constant, hence:

T₁ / V₁ = T₂ / V₂, this is also known as the Charles' law. what I did above was it's derivation

Finding final volume:

plugging the given values:

348/400 = 368 / x

x = 368*400 / 348

x = 422.9 mL

Answer:

The gas A is likely to have the lowest temperature

Explanation:

In a gas, the kinetic energy is directly proportional to the temperature under constant pressure and volume.

As you can see in the problem, the average of A has a low kinetic energy. But the average is increasing between B, C and D.

As the gas A has the lowest average kinetic energy:

[tex]\huge{\textbf{\textsf{{\color{pink}{An}}{\red{sw}}{\orange{er}} {\color{yellow}{:}}}}}[/tex]

An oil refinery or petroleum refinery is an industrial process plant where crude oil is transformed and refined into useful products such as petroleum naphtha, gasoline, diesel fuel, asphalt base, heating oil, kerosene, liquefied petroleum gas, jet fuel and fuel oils.

Answer:

This is because of diffusion , the movement of particles from an area of high concentration to an area of low concentration. ... This means that diffusion does not happen in solids – the particles in a solid can only vibrate and cannot move from place to place.

Answer:

Solids cannot diffuse each other because they are tightly packed and they are rigid and do not have fluidity.

Explanation:

The retina is the back part of the eye that contains the cells that respond to light. These specialized cells are called photoreceptors. ... The rods are most sensitive to light and dark changes, shape and movement and contain only one type of light-sensitive pigment. Rods are not good for color vision.

The retina is the back thing of the eye that has the cells that respond to the light. These specialized cells are known as photoreceptors.

Answer:

All of these answers are correct.

Explanation:

They are all correct because producers make their food(energy) through photosynthesis, they provide food to herbivores and therefore the rest of the food chain, and without them, the food chain would collapse and all the consumers would starve.

Answer:

0.00714 g

Explanation:

We know that the volume of one mole of a substance is 22400 cm^3

Thus;

1 mole of sulphur occupies 22400 cm^3

x moles of sulphur occupies 5.0 cm3

x = 5.0 cm3 * 1 mole/22400 cm^3

x = 2.23 * 10^-4 moles

Molar mass of sulphur = 32 g/mol

Mass of sulphur = 2.23 * 10^-4 moles * 32 g/mol

Mass of sulphur = 0.00714 g

Answer:

Introducing predator of silver carp or an invasive species that can feed upon silver carp

Explanation:

The solution is attached

Answer:

The correct answer is "85.71 mg".

Explanation:

The given values are:

Mass of drug,

= 3.0 mg

Mass percentage,

= 3.5%

As we know,

⇒  [tex]Mass \ percent = \frac{Mass \ of \ drug}{Mass \ of \ solution}\times 100[/tex]

Or,

⇒  [tex]Mass \ of \ solution = \frac{Mass \ of \ drug}{Mass \ percent}\times 100[/tex]

On substituting the values, we get

⇒                               [tex]=\frac{3.0}{3.5}\times 100[/tex]

⇒                               [tex]=0.8571\times 100[/tex]

⇒                               [tex]=85.71 \ mg[/tex]

Answer:

The loudness of sound is determined, in turn, by the intensity, or amount of energy, in sound waves. The unit of intensity is the decibel (dB) Intensity of sound results from two factors: the amplitude of the sound waves and how far they have traveled from the source of the sound.
