the electron cloud model describes which of the following

the group of protons that are in the nucleus

the neutron orbital

the negative charge of the electron

location where an electron has the highest probability of being found

Answers

Answer 1

The electron cloud model in physics describes the location where an electron has the highest probability of being found around an atom. Option D

The older Bohr model of the atom, which showed electrons orbiting the nucleus in set pathways like to planets orbiting the sun, was superseded by this one. Instead of representing electrons as particles in fixed orbits, the electron cloud model views electrons as a cloud-like region surrounding the nucleus, with each point representing the likelihood of finding an electron there.

This idea highlights how electrons are characterized by their quantum mechanical nature, which prevents them from being localized and instead allows them to be represented by probabilities within particular spatial regions surrounding the nucleus. Therefore, the understanding of electron dispersion surrounding the nucleus of an atom depends on the electron cloud model.

Answer 2

The electron cloud model describes the location where an electron has the highest probability of being found within an atom.

This model, also known as the quantum mechanical model, represents electrons not as definite orbits but as regions of probability called electron clouds.

It accounts for the wave-like nature of electrons and their distribution in atomic orbitals, where electrons are most likely to be found based on their energy levels and quantum numbers.

It does not describe the group of protons in the nucleus, the neutron orbital, or the negative charge of the electron; rather, it focuses on the spatial distribution of electrons in an atom.

In a complete sentence using all keywords below, describe how you can charge a balloon and have it stick to the wall?

Keywords: wool/felt/hair,, balloon, electrons, wall, negative charge, and positive charge.

Make sure to use all keywords correctly for 6 points.

Answers

Rub a balloon on a woolen fabric to pick up some electrons, to make the balloon negatively charged, and stick them to a wall, which would be positively charged to make them stick. 

Opposites attract and when you stick a negatively charged objects to positively charged objects, they tend to stick together. When you pick up electrons, it increases the number of electrons which will make the object negatively charged.

Answers

The Ideal Gas Law makes a few assumptions from the Kinetic-Molecular Theory. These assumptions make our work much easier but aren't true under all conditions. The assumptions are,

1) Particles of a gas have virtually no volume and are like single points.
2) Particles exhibit no attractions or repulsions between them.
3) Particles are in continuous, random motion.
4) Collisions between particles are elastic, meaning basically that when they collide, they don't lose any energy.
5) The average kinetic energy is the same for all gasses at a given temperature, regardless of the identity of the gas.

It's generally true that gasses are mostly empty space and their particles occupy very little volume. Gasses are usually far enough apart that they exhibit very little attractive or repulsive forces. When energetic, the gas particles are also in fairly continuous motion, and without other forces, the motion is basically random. Collisions absorb very little energy, and the average KE is pretty close.

Most of these assumptions are dependent on having gas particles very spread apart. When is that true? Think about the other gas laws to remember what properties are related to volume.

A gas with a low pressure and a high temperature will be spread out and therefore exhibit ideal properties.

So, in analyzing the four choices given, we look for low P and high T.

A is at absolute zero, which is pretty much impossible, and definitely does not describe a gas. We rule this out immediately.

B and D are at the same temperature (273 K, or 0 °C), but C is at 100 K, or -173 K. This is very cold, so we rule that out.

We move on to comparing the pressures of B and D. Remember, a low pressure means the particles are more spread out. B has P = 1 Pa, but D has 100 kPa. We need the same units to confirm. Based on our metric prefixes, we know that kPa is kilopascals, and is thus 1000 pascals. So, the pressure of D is five orders of magnitude greater! Thus, the answer is B.

I see three (3) question in the picture.
Here are the answers:

#1).
The total effective resistance of resistors in series is
the sum of the individuals.

(4 + 8 + 12) = 24 ohms.

Current = (voltage) / (resistance)  =  (24 V) / (24 ohms)  =  1 Ampere.

#2).
To answer this question, we don't care what the
total effective resistance is.
The resistors are in parallel, so each one is connected
directly to the terminals of the battery, and each resistor
has 24 V across it.

Current through the 4-ohm resistor = (voltage) / (resistance)

                                                        =  (24 V) / (4 ohms)

                                                        =         6 Amperes.

#3).
In a series circuit, the total effective resistance is 
the sum of the individual resistors, and the current
is (battery voltage) / (total effective resistance).

If pone resistor is replaced with a resistor of lower resistance,
then the sum of the individuals is less, and the current in the
series circuit increases (if the battery can handle it).

The mass of a full bottle of cooking oil is 1.30 kg when half Is empty calculate mass of empty bottle

Answers

Mass of bottle + cooking oil = 1.3 kg

A balloon filled with helium occupies 20.0 l at 1.50 atm and 25.0◦
c. how many moles of helium will there be in the balloon at stp?

Answers

Final answer:

By applying the Ideal Gas Law, we find that the helium balloon contains approximately 1.22 moles under the given conditions. This mole amount remains consistent at standard temperature and pressure (STP) as no gas is added or removed.

Explanation:

Your question pertains to the concepts of chemical stoichiometry and the gas laws. Given the conditions and the volume of the gas, we start by converting the initial conditions to Standard Temperature and Pressure (STP). Your balloon containing helium is at a volume of 20.0 L, a pressure of 1.50 atm, and a temperature of 25.0°C (or 298.15 K in absolute temperature).

The Ideal Gas Law (PV=nRT) allows us to calculate the number of moles (n) in the balloon initially: n = PV/RT = (1.50 atm * 20.0 L) / (0.0821 L*atm/mol*K * 298.15 K) which results in approximately 1.22 mol of helium.

Now, to find the number of moles at STP, we need to remember that the number of moles remains the same as long as no gas is added or removed. Therefore, your balloon contains approximately 1.22 moles of helium at STP as well.

There are approximately [tex]1.225\ moles[/tex] of helium in the balloon at STP (Standard Temperature and Pressure).

To find out how many moles of helium are in the balloon at STP (Standard Temperature and Pressure), we'll follow these steps:

Given Data

Volume of the balloon, [tex]\( V = 20.0 \) L[/tex]

Pressure of the helium gas,[tex]\( P = 1.50 \) atm[/tex]

Temperature of the helium gas, [tex]\( T = 25.0 \) ^\circ C[/tex]

Convert Temperature to Kelvin

First, convert the temperature from Celsius to Kelvin:

[tex]\[ T_{\text{Kelvin}} = T_{\text{Celsius}} + 273.15 \][/tex]

[tex]\[ T_{\text{Kelvin}} = 25.0^\circ C} + 273.15 \][/tex]

[tex]\[ T_{\text{Kelvin}} = 298.15 \text{ K} \][/tex]

Calculate the Number of Moles (using the Ideal Gas Law)

The ideal gas law equation relates the pressure, volume, temperature, and number of moles [tex](\( n \))[/tex] of a gas:

[tex]\[ PV = nRT \][/tex]

where:

[tex]\( P \)[/tex] is the pressure in atmospheres (atm)

[tex]\( V \)[/tex] is the volume in liters ([tex]L[/tex])

[tex]\( n \)[/tex] is the number of moles of gas

Select all that apply. A hypothesis is _____. always correct determined before experimentation begins the experimental factor that changes in response to a change in the independent variable testable and falsifiable

Answers

Final answer:

A hypothesis is a testable and falsifiable assumption known before experimentation. It's not always correct and does not always change in response to a change in the independent variable. Even when experiments support a hypothesis, it is not confirmed as absolutely correct.

Explanation:

A hypothesis is a testable and falsifiable assumption based on what is known. It is determined before any experiment begins and serves as a guide for the collection and analysis of data. For instance, we could formulate a hypothesis like, 'If I water plants with sugar-mixed water, they will grow faster.'. If subsequent experimentation disproves this hypothesis, it must be discarded or reformed.

A hypothesis does not necessarily change in response to a change in the independent variable; rather, it predicts the expected response or outcome. However, a hypothesis is not always correct. It represents our best prediction based on the current information and can often be proven wrong as new data or insights become available via further empirical research.

Furthermore, in scientific research, even though a hypothesis is supported by multiple experiments, it does not confirm it to be correct, as future experiments could contradict it. Also, if a hypothesis explains a large amount of experimental data it could be considered a theory, but even theories can be modified if new data appears.

How much heat is needed to change 5.42 grams of solid gold to liquid gold at its melting point of 1,063°C? The latent heat of fusion of gold is 66.6 J/g.

Answers


[tex]5.42 \times 66.6 = 360.972[/tex]
360.972 J

Answer:

360.97 J

Explanation:

mass of gold, m = 5.42 g

Latent heat of fusion, L = 66.6 J/g

The amount of heat required to convert 1 kg of solid into liquid state at its melting point is called latent heat.

L = Heat / mass

So, L = Q / m

Q = m L

Where, Q is the amount of heat supplied and L be latent heat of fusion amd m be the mass of substance.

Q = 5.42 x 66.6

Q = 360.97 J

Thus, the amount of heat required to melt the desired amount of gold is 360.97 J.

The intensity of the magnetic force F experienced by a charge q moving with speed v in a magnetic field of intensity B is equal to
[tex]F=qvB \sin \theta[/tex]
where [tex]\theta[/tex] is the angle between the directions of v and B.

1) Re-arranging the previous formula, we can calculate the value of the magnetic field intensity. The charge is [tex]q=2.7 \mu C=2.7 \cdot 10^{-6}C[/tex]. In this case, v and B are perpendicular, so [tex]\theta=90^{\circ}[/tex], therefore we have:
[tex]B= \frac{F}{qv \sin \theta} = \frac{5.75 \cdot 10^{-3}N}{(2.7 \cdot 10^{-6}C)(773m/s)\sin 90^{\circ}}=2.8 T [/tex]

2) In this second case, the angle between v and B is [tex]\theta=55^{\circ}[/tex]. The charge is now [tex]q=42.0 \mu C=42.0 \cdot 10^{-6}C[/tex], and the magnetic field is the one we found in the previous part, B=2.8 T, so we can find the intensity of the force experienced by this second charge:
[tex]F=qvB \sin \theta=(42\cdot 10^{-6}C)(1.21 \cdot 10^3 m/s)(2.8 T)(\sin 55^{\circ})=0.12 N[/tex]

A. As the wagon approaches the bottom of the hill, the potential energy decreases and the kinetic energy increases.

B. The kinetic energy decreases as the wagon comes towards the bottom of the hill.

C. As the wagon approaches the bottom of the hill, the potential energy and the kinetic energy both increase.

D. The thermal energy decreases as the wagon comes towards the bottom of the hill.,

Answers

A. As the wagon approaches the bottom of the hill, the potential energy decreases and the kinetic energy increases. Potential energy and kinetic energy are opposites. At the top of the hill the wagon has max potential energy and no kinetic energy. At the bottom of the hill the wagon has max kinetic energy and no potential energy. So as the wagon approaches the bottom of the hill potential energy decreases and kinetic energy increases.

Answer:

As the wagon approaches the bottom of the hill, the potential energy decreases and the kinetic energy increases.

Explanation:

There are two types of energy possessed in the wagon i.e. potential energy and the kinetic energy. As a wagon is accelerating down a hill, its potential energy decreases and the kinetic energy increases.

We know that the energy possessed due to its height above ground level is called its potential energy while the energy possessed due to its motion is called its kinetic energy.

So, the correct option is (A) " As the wagon approaches the bottom of the hill, the potential energy decreases and the kinetic energy increases".

Answers

The current flowing in the circuit with a potential difference of 9 volts and resistance of 47 ohms is approximately 0.1915 amperes (A), calculated using Ohm's Law (I = V/R).

The current that flows through a circuit can be calculated using Ohm's Law, which is given by the formula V = IR, where V is the potential difference, I is the current, and R is the resistance. In this case, the potential difference is 9 volts (V) and the resistance is 47 ohms (Ω). To find the current, we rearrange the formula to I = V/R.

Substitute the given values into the formula:

I = 9V / 47Ω

I ≈ 0.1915 A

So the current flowing in the circuit is approximately 0.1915 amperes (A).
