Put the following objects in order to of increasing kinetic molecular energy.

helium balloons
hot coffee
slime
limestone

Answers

Answer 1

Answer:

limestone < slime < hot coffee < helium balloons

Explanation:

The order is based on the average kinetic energy of the particles in each object. The order increases as the temperature of the object increases, causing the particles to move faster and have more kinetic energy.

1. Limestone: Solid-state mineral with relatively low temperature and slow-moving particles, lowest kinetic energy among the objects listed.

2. Slime: A non-Newtonian fluid that can be considered as a soft solid, its particles have more kinetic energy than solid limestone, but less than a liquid like hot coffee.

3. Hot Coffee: A liquid with a higher temperature than the other objects, particles have more kinetic energy compared to solid or non-Newtonian fluid.

4. Helium Balloons: Gas with a higher temperature than the other objects, particles have the highest kinetic energy among the objects listed, resulting in the balloon expanding and rising.

Answer 2
Limestone , slime, hot coffe , helium balloons

Answers

The number of atoms in 29.0grams of sodium, Na is 7.58 × 10²³ atoms.

How to calculate number of atoms?

The number of atoms of a substance can be calculated by multiplying the number of moles in the substance by Avogadro's number; 6.02 × 10²³.

no of atoms = no of moles × 6.02 × 10²³

According to this question, there are 29.0 grams of sodium (Na). The number of moles can be calculated as follows:

moles = 29.0g ÷ 22.99g/mol = 1.26mol

Answers

For the given reaction, increasing the volume of the reaction system will shift the equilibrium to forward reaction. Decreasing the pressure will shift the equilibrium to the reverse direction.

What is chemical equilibrium ?

The state of a reaction at which, the back ward and forward reaction takes place in equal rates is called equilibrium state. According to Le -Chatlier's principal, if any disorder imbalance the system, the system will balance it and shift to a new equilibrium state.

When the volume of reactants is increased, the reaction changes to the forward direction in which the increased volume is decreased.  Hence, as the volume increases, forward reaction takes place.

When the pressure is decreased, the reaction will shift to the direction in which the number of moles of gas is increasing to increase the pressure. Here, the reactant side haves the 4 moles of gases and product side have 2 moles of gas.

"ground state." In ground state all electrons are in the lowest energy levels available. When atoms or ions are heated, some electrons may absorb enough energy to
allow them to "jump" to higher energy levels. The atom or ion is then said to be in the "excited state." The electrons cannot remain in this excited state for long and will
emit energy in the form of light when they return to ground state. It is this light we see when an atom is heated in a flame. The frequency or color of light emitted

Suppose a different fatty acid molecule were used, with a molecular volume of 4.48 x 10-22 mL/molecule, and a molar mass of 235 g/mol. Use these data and the expected value for Avogadro's number to calculate its density (g/mL) by dimensional analysis. Hint: try starting with 235 g over 1 mole.

Answers

Density (g/mL) can be calculated as mass per volume.

Mass = molar mass (g/mol) * number of moles
Volume = molecular volume (mL/molecule) * Avogadro's number

Mass = 235 g/mol * 1 mole
Volume = 4.48 x 10^-22 mL/molecule * 6.022 x 10^23 molecules/mol

Density (g/mL) = Mass / Volume
Density (g/mL) = 235 g/mol / (4.48 x 10^-22 mL/molecule * 6.022 x 10^23 molecules/mol)

This calculation yields a density of approximately 0.77 g/mL

1.25 moles of gas is held at a temperature of -4.5°C. What is the volume of the gas if the pressure is 1.20 atm?

Answers

The volume of a gas can be calculated using the Ideal Gas Law: PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant (8.31 J/mol·K), and T is the temperature in Kelvin.

First, we need to convert the temperature to Kelvin: T = -4.5°C + 273.15 = 268.65 K

Next, we can plug in the values and solve for V:
V = (nRT)/P = (1.25 moles * 8.31 J/mol·K * 268.65 K) / 1.20 atm = 245.84 L.

So, the volume of the gas is 245.84 liters

Answers

The mass of Fluorine in grams in the second sample is 2066 g. The concept law of definite proportions is used here to obtain the mass of Fluorine in the second sample.

What is law of definite proportions?

This law was stated by a French chemist, Louis Proust. It states that 'a chemical compound always contains the same elements combined together in the same proportion by mass'.

The mass of Mg in sample 1 is 1.66 kg and that of F is 2.56 kg. The mass of Mg in sample 2 is 1.34 kg and we have to find out the mass of F in second sample.

The mass of Fluorine in sample 2 can be obtained by using the mass ratio of the elements in sample 1.

In sample 1:

Mass of magnesium ÷ Mass of Fluorine = 1.66 kg ÷ 2.56 kg

In sample 2:

By using dimensional analysis,

Mass of Fluorine = 2.56 kg Fluorine ÷ 1.66 kg Magnesium × 1.34 kg Magnesium

Therefore the mass of Fluorine = 2.066 kg

The mass in kilogram can be converted into grams as:

Mass of Fluorine = 2.066 kg × 1000 g ÷ 1 kg = 2066 g

Thus the mass of Fluorine in the second sample is 2066 g.

The term mole is defined as the amount of substance of a system which contains as many elementary entities.

One mole of any substance is equal to 6.023 × 10²³ units of that substance such as atoms, molecules, or ions. The number 6.023 × 10²³ is called as Avogadro's number or Avogadro's constant.

If the temperature of a cup of coffee decreases from
60.0°C to 25.0°C, what is the decrease in temperature in
units of degrees Celsius and kelvin?

Answers

To convert from Celsuis to Kelvin, add 273 or vice versa to convert from Kelvin to Celsuis.

So 60 Celsius + 273 = 333K

and 25 + 273 = 298K

Therefore we can see the decrease in temperature in units of degrees and Celsuis is 35.

The wavelength and speed of a wave can be influenced by many factors. Adjust the amplitude and frequency as described in the table below. Then complete the chart to report whenever this causes the wavelength or wave height to increase or decrease. Also tell what effect the change will have on how the wave sounds. Return each variable to its original value after each experiment

Answers

The speed of the sound would increase as the wave speed increase.

What is the effect of the wavelength on the speed of sound?

We have to know that the speed of the sound is dependent on the wavelength and the relationship is a direct relationship if the frequency of the sound has been kept as a constant.

We can now be able to write that;

v = λf

v = wave speed

f = frequency

λ = wavelength

Now we can see that is we increase the wavelength of the sound then the wave speed of the sound would also increase .

Which of the following is the equation for impulse?

impulse =p

impulse =mv

impulse =FΔt

impulse =ma

Answers

The correct equation for impulse is FΔt. The third option.

What is impulse?

In mechanics, the impulse is the amount of force applied to an object for a certain amount of time leading to a change in the momentum of the object.

The impulse is mathematically expressed as:

Impulse = FΔt

Where F is the amount of force applied in Newton and Δt is the changes in the time spent applying the force. In other words, impulse is the product of force in Newtons and time in seconds.

Thus:

Impulse is not pImpulse is not mvImpulse is not ma
