<em>[H⁺] = 1,7×10⁻⁹ mol/dm³</em>
pH = -log[H⁺]
pH = -log[<span>1,7×10⁻⁹]
<u>pH = 8,77</u>
pH + pOH = 14
pOH = 14-8,77
<u>pOH = 5,23

Communities is all the populations living in an ecosystem at the same time. A predator-prey relationship is an organism that eats another organism.
Answer:
One mole of a substance is equal to 6.022 × 10²³ units of that substance (atoms, molecules, or ions)
Explanation:
This number is Avogadro's number. The concept of the mole can be used to convert between mass and number of particles. its used to compare very large numbers.
I believe it is the dependent variable b/c it is the thing(s) that is been observe or measure
