When Kw = [OH-] [H+] & when we know that the pure water should has the concentration of H [ H+] = the concentration of OH [OH-]So
[H+]=[OH-]
∴ we can assume that Kw = [H+] [H+] or Kw = [OH-] [ OH-] or we can assume [H+] or [ OH-] as z
So, then Kw = Z^2
when we have the value of Kw so, by substitution:
Z^2 = 1.2 x 10 ^-13
Z = √ 1.2x10^-13
= 3.46x 10^-7
So we now get [H+] = 3.46X10^-7
when PH = -㏒[H+]
∴ PH = -㏒(3.46x10^-7) = 6.46
Answer:
FART = gas from ur bottom like when u eat too much beans (¬‿¬)
Explanation:
<em>Scientists believe water currents within the earth's mantle are slowly causing the plates above to move
</em>
<em></em>
<em>Answer: </em><u><em>True</em></u>
<u><em /></u>
<u><em>EXplanation:</em></u>
<u><em /></u>
<u><em>The common, simplified explanation for why tectonic plates are moving is that they're carried along on currents in the upper mantle, the slowly flowing layer of rock just below the Earth's crust. Converging currents drive plates into each other. Diverging currents pull them apart</em></u>
They send warmer and colder temperatures to different places (I may be wrong so you should just pick the answer above mine)
Answer:
Mass = 35.02 g
Explanation:
Given data:
Number of moles = 1.75 mol
Mass of HF = ?
Solution:
Formula:
Mass = number of moles × molar mass
Molar mass of HF = 20.01 g/mol
by putting values,
Mass = 1.75 mol × 20.01 g/mol
Mass = 35.02 g
