  • A specific state which is defined being a property without the path taken to achieve that state based on it, is understood as a state function. 
  • While the functions whose value is based on the direction taken among two states are named direction or path functions, on the other hand.
  • The system's thermodynamic condition relates to the current material in temperature, pressure and quantity.
  • State functions rely only on certain requirements and not on how they have been achieved. State functions for an instance, involve entropy, density, enthalpy and internal energy.
  • They are known as state functions as they quantitatively define a thermodynamic system's equilibrium condition, regardless of how the system landed in that condition.

A solution of baking soda and water has a pH of 8.40. What type of solution is this?
Gwar [14]
The solution is basic.
pH scale can be used to find out how acidic or basic a solution is .
When pH = 7 the solution is neutral,
pH < 7 solution is acidic
pH > 7 solution is neutral
Since the pH of solution is 8.40 then value is more than 7 therefore baking Soda and water is basic.

Calculate the volume (liters) of solution that can be prepared from 180. grams of K2Cr2O7 for a 0.200M solution.
Sladkaya [172]

Answer:

The volume of the solution is 0.305 liters.

Explanation:

Molar mass is the amount of mass that a substance contains in one mole. The molar mass of K₂Cr₂O₇ is 294 g / mole. Then you can apply the following rule of three: if by definition of molar mass 294 grams of the compound are contained in 1 mole, 180 grams are contained in how many moles?

moles=\frac{180 grams*1mole}{294 grams}

moles= 0.61

Molarity is a measure of the concentration of a substance that is defined as the number of moles contained in a certain volume. So, the molarity of a solution is calculated by dividing the moles of the solute by the volume of the solution:

molarity=\frac{number of moles of solute}{volume}

Molarity is expressed in units \frac{moles}{liter}.

In this case:

  • molarity= 2 M
  • number of moles of solute= 0.61 moles
  • volume= ?

Replacing in the definition of molarity:

2 M=\frac{0.61 moles}{volume}

Solving:

volume=\frac{0.61 moles}{2 M}

volume= 0.305 liters

<u><em>The volume of the solution is 0.305 liters.</em></u>
