# Delta and ksp relationship quizzes

### Chapter 1. Calculating and Getting into Orbit — Spaceflight on Budget in KSP and real world

Consider the two** equations that deal with Delta G (∆G). One of the changes was to remove equation #2 below from the equations. What is the value of delta G for the precipitation of AL(OH)3 at 25 C? This is what I came I then solved for x^2 and plugged it into the equation. Gibbs Free Energy and the Relationship between Delta G, Delta H, and Delta S Quiz (9 Questions). Lecture contents locked.

Notice that the change in freezing or boiling temperature depends solely on the nature of the solvent, not on the identity of the solute. One valuable use of these relationships is to determine the molecular mass of various dissolved substances.

As an example, perform such a calculation to find the molecular mass of the organic compound santonic acid, which dissolves in benzene or chloroform.

A solution of 50 grams of santonic acid in grams of benzene boils at Referring to Table for the boiling point of pure benzene, the boiling point elevation is That concentration is the number of moles per kilogram of benzene, but the solution used only grams of the solvent.

The moles of santonic acid is found as follows: You can also find this value by using the freezing point of the solution. In the two previous examples, the sucrose and santonic acid existed in solution as molecules, instead of dissociating to ions. The latter case requires the total molality of all ionic species. Calculate the total ionic molality of a solution of Because the gram formula weight of AlBr 3 is Specific impulse of the engine is s.

Put these figures in the equation, get the result: Now, knowing all that, we can assemble a simple rocket to send a pod in the sky. Then I add a big tank and a Poodle engine.

A ship with a huge RSC tank to imitate payload.

The same ship with Poodle engine and a liquid fuel tank. Note that if you add a tank and an engine, both of them are included in m1 and m0 parameters, and Isp changes too. I made a spreadsheet in OpenOffice to make things easier and avoid confusion. But if you add stages things start become more complicated, the process is long, and you might ask yourself: Yes, there is Flight Engineer Redux by cybutek.

After you add a plugin part to a ship, it will show you live stats on its every stage: MechJeb —the famous autopilot mod— also has a window for that, although without the ability to calculate for other planets.

## Homework Help: Calculating free energy from Ksp

If we add the orange tank and Mainsail engine, the ship should almost get into orbit. We can add the smallest wide tank to be safe. Is a Mainsail powerful enough here? This is another important value to consider: If thrust equals weight, TWR is 1. Lower TWR means the rocket falls down, but slower than free fall.
