All colors but red is being absorbed by the material.
Answer:
pH of the solution after addition of 8 ml 0,296 molar HCl = 7.94
Explanation:
In this case buffer exist between hypochlorous acid HClO is a weak acid and its conjugate base hypochlorite ion ClO⁻ which are deliver to the solution by NaOCl ( sodium hypochlorite ).
The salt is completely dissociate
[NaOCl] = [ClO⁻]
Using Henderson equation to find pH of this buffer
pH = pKa + log![\frac{[Conjugate base]}{[Acid]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BConjugate%20base%5D%7D%7B%5BAcid%5D%7D)
or, = 7.53 + log
or, = 7.53 + 0.4
or, = 7.94
Answer:
1) They are the same line so they match equally bc they are measuring the same thing just one is more specific than the other
2) Sonar measures all depths at every possible point and maps it including all the gaps in between the 5cm apart the ocean floor is. The difference between the points could be a cliff or a smooth decline.
The balanced chemical reaction is:
C3H8 + 5O2 = 3CO2 + 4H2O
We are given the amount of C3H8 to be used for the reaction. This will be the starting point for the calculations.
73.7 g C3H8 (1 mol C3H8 / 44.11 g C3H8) ( 5 mol O2 / 1 mol C3H8 ) ( 32 g O2 / 1 mol O2 ) = 267.3 g O2
Sr has an atomic number of 38 so we'll start there.
The closest noble gas is Kr with an atomic number of 36 so it'll look like this:
[Kr]5s^2.
