the enthalpy of vaporization (δhvap) for acetone is 31.0 kj/mol at 25.00°c. calculate the entropy change of the surroundings in j/k when 50.0 g of acetone (c3h6o) evaporates at 25.00°c.

Answers

Answer 1

To calculate the entropy change of the surroundings, we need to use the formula ΔS = -ΔHvap/T, where ΔHvap is the enthalpy of vaporization, T is the temperature in Kelvin, and the negative sign indicates that the surroundings are losing entropy.

First, we need to convert the amount of acetone from grams to moles. Using the molar mass of acetone (58.08 g/mol), we find that 50.0 g of acetone is 0.861 mol.

Next, we can use the given enthalpy of vaporization to calculate the energy released when 0.861 mol of acetone evaporates. ΔHvap = 31.0 kJ/mol x 0.861 mol = 26.7 kJ.

Finally, we can calculate the entropy change of the surroundings by plugging in the values into the formula: ΔS = -ΔHvap/T = -(26.7 kJ) / (298 K) = -89.6 J/K.

Therefore, the entropy change of the surroundings is -89.6 J/K when 50.0 g of acetone evaporates at 25.00°C.

"Displacement" describes a change in an object's location. An arrow pointing from the starting point to the finishing point serves as the object's symbol. For instance, an object's position changes if it shifts from position A to position B. For instance, an object's position changes if it shifts from position A to position B.

#SPJ1

Answer:Blank one: 2 kmBlank two: 0 km

If you walked one kilometer from your home to the store and then one kilometer back home, you did indeed cover a distance of two kilometers. The distance is calculated by adding the lengths of the two separate paths together, which in this case would be 1 kilometer + 1 kilometer = 2 kilometers.

However, when we talk about displacement, we're referring to the change in position or the shortest straight-line distance between your starting point and your ending point. In this scenario, since you ended up back at your starting point, your displacement is 0 kilometers. This is because the straight-line distance from your home to the store is canceled out by the straight-line distance from the store back to your home.

To better understand this concept, let's consider an example. Imagine you take a trip around a circular track. You start at one point, go all the way around the track, and end up back at the starting point. Even though you covered a certain distance along the track, your displacement is still 0 because you ended up back where you started.

So, in summary, the distance you walked is 2 kilometers, but your displacement is 0 kilometers because you returned to your starting point.

A thread holds two carts together on a frictionless surface. A spring is compressed between the two carts. After the thread between the two carts is cut the cart on the left with a mass of 1. 5 kg moves away with a velocity of 27 cm/s. What is the velocity of the cart on the right that has a mass of 4. 5 kg?.

Answers

The velocity of the cart on the right that has a mass of 4. 5 kg is 0.09 m/s.

Velocity is the rate of change of distance with respect to time.

It has the SI unit as m/sec.

Mass on the left of the cart = m1 = 1.5 kg

on the left of the cart = v1 = 27 cm/s = 0.27m/s

Mass on the right of the cart = 4.5 kg

Velocity on the right of the cart = x

According to the law of conservation of linear momentum:

We can say that.

Initial momentum will equalize the final momentum.

And momentum is the product of mass and its velocity.

Assigning one of its velocity as negative because both are in different direction.

mathematically, (m1*-v1) + (m2v2) = 0

(1.5*-0.27) + (4.4*x) = 0

x = 0.09 m/s

So the velocity of the cart on the right side that has a mass of  is 0.09 m/s.

What are the domain and range of FX =- 37?

Answers

The domain of f(x) = –37 is all the real numbers. And, the range of f(x) = –37 is y = –37.

The given function f(x) = –37 is a horizontal line which goes from negative infinity to positive infinity.

In this case, the domain can be any number since there is no limit on what the x value can be.

So, the domain of the given function f(x) = –37 will be all real numbers.

And, the range will always be y = –37 because no matter what x value will equal, y will always be equal to –37 in the function of f(x) = –37.

So, the range of the given function f(x) = –37 will be y = –37.
