HCl = H⁺ + Cl⁻
c(HCl)=9.8*10⁻⁵ mol/l
pH=-lg[H⁺]
[H⁺]=c(HCl)
pH=-lg{c(HCl)}
pH=-lg{9.8*10⁻⁵}=4.009
pH=4.009
Answer:
0.11 M.
Explanation:
Hello!
In this case, since the molarity is computed as the moles of solute divided by the volume of solution in L, we first need to compute the moles of potassium in 99.7 mg as shown below:
Moreover, given the density of the seawater (mixture containing the K and other solutes), we can compute the liters as shown below:
Therefore, the molarity turns out:
Best regards!
Answer:
i think its a mixture because it has different things mixed with it like chocolate, marshmallows and other stuff
Explanation:
It changes because when the 2 tectonic plates collide they form mountains and volcanoes.
Continental drift causes tectonic plates to either "pull apart" or "crash" into each other.
Plates that crash into each other either form mountains, or when one slides under the other (a subduction zone) volcanoes from.
