The balanced equation for the acid base reaction is as follows
NaOH + HCl ---> NaCl + H₂O
stoichiometry of NaOH to HCl is 1:1
the number of NaOH moles reacted - 0.200 mol/L x 0.0250 L = 0.005 mol
according to molar ratio
number of NaOH moles reacted = number of HCl moles reacted 
therefore number of HCl moles - 0.005 mol 
volume of 30.0  mL contains 0.005 mol
therefore 1000 mL contains - 0.005 mol / 0.030 L = 0.167 M
concentration of HCl is 0.167 M

Distilled water and sealed container are in equilibrium when these objects do not exchange more heat.

<h3>What is thermal equilibrium?</h3>

The expression 'thermal equilibrium' makes references to the phenomenon by which two objects interact with each other to exchange heat energy.

Objects in contact can transfer heat to reach a thermal equilibrium state where the temperature is the same for both objects.

In conclusion, distilled water and sealed container are in equilibrium when these objects do not exchange more heat.

The road map in the text shows that to convert from one unit to another, you must use the ____ as an intermediate step. ___ conv
jonny [76]

Answer:

Conversion factor;

Molar mass;

Avogadro's constant and molar mass

Explanation:

  • Firstly, an intermediate step is to define the conversion factor that will be then used in a conversion technique called dimensional analysis in order to convert from one unit to another. An example of a conversion factor would be, for example, 1 L = 1000 mL, which can be manipulated as a fraction, either \frac{1 L}{1000 mL} or \frac{1000 mL}{1 L};
  • Secondly, in order to convert mass to moles, we need to know the molar mass of a compound which has a units of g/mol (that is, it shows how many grams we have per 1 mole of substance.
  • Thirdly, Avogadro's constant, N_A = 6.022\cdot 10^{23} mol^{-1} tells us that there is N_A number of molecules or atoms in 1 mole of substance. We need two conversion factors to convert the number of molecules to a mass: firstly, we need to convert the number of molecules into the number of moles using Avogadro's constant and then we need to use the molar mass to convert the moles obtained into mass.
