which of these materials will thermalize the slowest (in other words, reach thermal equilibrium the slowest)?

Answers

Answer 1

The material that will thermalize the slowest is the one that has the highest thermal conductivity.

The thermal conductivity of a material is a measure of how well it conducts heat. Materials with high thermal conductivity will transfer heat quickly and therefore thermalize faster than materials with low thermal conductivity. Conversely, materials with low thermal conductivity will transfer heat slowly and will thermalize more slowly. It's worth noting that there are other factors that can affect how quickly a material thermalizes such as the specific heat capacity, temperature difference and the mass of the material.

A rocket travels in a straight line at a speed of 5000 m/s. After 1 min, it is 10,000 m/s. What is the rocket's acceleration?

Answers

A rocket travels in a straight line at a speed of 5000 m/s. After 1 min, it is 10,000 m/s. 83.33ms⁻² is the rocket's acceleration.

What is an acceleration ?

The rate of change of velocity is defined as acceleration. Acceleration usually indicates that the speed is changing, but this is not always the case. When an object moves in a circular path at a constant speed, it is still accelerating because its velocity direction changes.

Vf = Vo + at

Vf = Final velocity

Vo = Initial Velocity

a = acceleration

t = time required

Making "a" the subject

a = Vf - Vo/(t)

a = 10,000–5,000/(60)

a = 5,000/60

a = 83.33ms⁻²

Thus, 83.33ms⁻² is the rocket's acceleration.

50 points

Answers

To convert the pressure inside the bag from mm Hg to kPa, we can use the conversion factor:

1 kPa = 7.5 mm Hg

So, we can divide the pressure in mm Hg by 7.5:

761.3 mm Hg / 7.5 = 101.5 kPa

So, the pressure inside the bag of potato chips is approximately 101.5 kPa.

It is important to note that the conversion factor of 1 kPa = 7.5 mm Hg, is an approximation and it can vary depending on the temperature and altitude.

Therefore, the pressure inside the bag of potato chip in kPa is 101 kPa (rounded to the nearest whole number)

Charlotte is driving at 69.8 mi/h and receives a text message. She looks down at her phone and takes her eyes off the road for 3.27 s.  102.02 m  far has Charlotte traveled in feet during this time.

What is speed ?

The term speed is defined as the rate of change of position of an object in any direction.

Given:

The speed at which charlotte is driving = 69.8 mi/h

The time which she took of her eyes from the road = 3.27 s

During the entire journey, the time at which she took her eyes off the road, she is probably not driving.

We will have to convert the 69.8 mi/h to m/s

Since 1 mi/hr = 0.44704 m/s

69.8 mi/h will be:

= (69.8 mi/hr × 0.44704 m/s) ÷ 1 mi/hr

= 31.20 m/s

Now, using the relation:

Speed = distance/ time

31.20 m/s = (distance)  / 3.27s

By Cross multiplying

Distance = 31.20 m/s  × 3.27s

Distance = 102.02 m

What mass of liquid oxygen (LOX) would be
needed to burn 190.3 g of B₂H6?
Answer in units of g. Answer in units of g.

Answers

Answer:

1583.76 g O2

Explanation:

For every one molecule of B2H6 that reacts, 3 molecules of O2 are needed. To determine the mass of liquid oxygen (LOX) needed to burn 190.3 g of B2H6, use the balanced equation as a conversion factor.

1 mole of B2H6 = 28.02 g

1 mole of O2 = 32 g

Using the balanced equation above, you know that for every 1 mole of B2H6, 3 moles of O2 are needed.

Therefore, the mass of O2 needed for 190.3 g of B2H6 is:

190.3 g B2H6 * (3 moles O2 / 1 mole B2H6) * (32 g O2 / 1 mole O2) = 1583.76 g O2

Therefore, the amount of each reactant must be equal to the amount of each product. By looking at the chemical equation and the amount of each reactant, the limiting reactant is the one that is used up first and therefore determines the amount of products that can be made. The excess reactant is the one that is left over once the limiting reactant has been exhausted. For example, in problem 9, the equation is 2H2O + O2 →→ 2H2O2 and the amounts are 5 mol H2O and 15 mol O2. Since oxygen is used up first, it is the limiting reactant and hydrogen is the excess reactant. In problem 10, the equation is Mg(OH)2 + 2HCI→→ MgCl2 + 2H2O and the amounts are 6 mol Mg(OH)2 and 20 mol HCI.Since magnesium is used up first, it is the limiting reactant and hydrochloric acid is the excess reactant. In problem 11, the equation is 3Zn + Fe2O3→ 3ZnO + 2Fe and the amounts are 4 mol Zn and 2 mol Fe2O3. Since zinc is used up first, it is the limiting reactant and iron oxide is the excess reactant. In problem 12, the equation is CuSO4 + 2AgNO3 → Cu(NO3)2 + Ag₂SO4 and the amounts are 13 mol CuSO4 and 22 mol AgNO3.

The free-energy change, ΔG, for the chemical reaction A → B is 0 kcal/mole at 37°C when the concentrations of A and B are 10 M and 0.1 M, respectively. What is the free-energy change for the reaction when the concentrations of A and B are 0.01 M and 1 M, respectively?

Answers

The free energy change for the same reaction when the concentrations of A and B are 0.01 M and 1 M, respectively, is -2.501 kJ/mol.

The free energy change, ΔG, for the chemical reaction A → B is determined by the equation ΔG = -RT ln(K), where R is the gas constant, T is the temperature, and K is the equilibrium constant.

Because the temperature of the reaction is held constant, the ΔG will remain the same no matter what the concentrations of A and B are.

To calculate the free energy change for the reaction when the concentrations of A and B are 0.01 M and 1 M, respectively, we need to calculate the new equilibrium constant, K.

K is equal to the product of the concentrations divided by the reactants. For this reaction, K = (1 M)(0.01 M)/(10 M) = 0.001.

Plugging this value of K into the equation for ΔG,we get

ΔG = -RT ln(K) = -(8.314 J/K mol)(310 K) ln(0.001) = -2.501 kJ/mol.

The mass of B2H6 is given as 190.3 g, and the molar mass of B2H6 is 27.66964 g/mol.

So using this molar mass, we can find the number of moles of B2H6 using the following calculation:

190.3 g / 27.66964 g/mol = 6.918 moles of B2H6

Now we use the balanced equation to find the number of moles of O2 that are needed.

B2H6(g) + 3 O2(l) → 2 HBO2(g) + 2 H2O(l)

The coefficient of O2 on the reactant side is 3, so for every 3 moles of O2 consumed, 2 moles of B2H6 are consumed.

Therefore, we can use the following conversion factors to find the moles of O2 needed:

6.918 moles B2H6 x 3 moles O2/2 moles B2H6 = 10.377 moles O2

To find the mass of O2 that is needed, we will use the molar mass of O2 which is 32 g/mol

10.377 moles O2 x 32 g/mol = 332.9 g O2

So the mass of liquid oxygen (LOX) that would be needed to burn 190.3 g of B2H6 is approximately 332.9 g.

For a single substance at atmospheric pressure, classify the following as describing a spontaneous process, a nonspontaneous process, or an equilibrium system.

Drag the appropriate items to their respective bins.

1) solid melting below its melting point

2) liquid vaporizing below its boiling point

3) gas condensing below its condensation point

4) solid and liquid together at the melting point with no net freezing or melting

5) liquid vaporizing above its boiling point

6) gas condensing above its condensation point

7) liquid freezing above its freezing point

8) solid melting above its melting point

9) liquid freezing below its freezing point

10) liquid and gas together at the boiling point with no net condensation or vaporization

Answers

The matching is as follows:

solid melting below its melting point → nonspontaneous processliquid vaporizing below its boiling point → spontaneous processgas condensing below its condensation point → spontaneous processsolid and liquid together at the melting point with no net freezing or melting  → Equilibrium systemliquid vaporizing above its boiling point → spontaneous processgas condensing above its condensation point → spontaneous processliquid freezing above its freezing point → nonspontaneous processsolid melting above its melting point → spontaneous processliquid freezing below its freezing point → spontaneous processliquid and gas together at the boiling point with no net condensation or vaporization → Equilibrium system


Spontaneous processes are processes that occur within the system itself as soon as it is started, no work is needed from outside the system (external work) for the process to continue. On the other hand, nonspontaneous processes will not occur unless external work is continuously applied

The statement above shows that the process that occurs spontaneously occurs in one direction (irreversible). Meanwhile, non-spontaneous reactions occur in the opposite direction (reversible).

It can be said to be in equilibrium, if the rate of the reaction to the right is equal to the rate. The reaction is to the left, so that the ratio of the concentrations of the reactants and products remains the same.
