Answer:
pH= 3.30
Explanation:
Hydrochloric acid is a strong acid that completely dissociates in water.
For a 0.00050 M HCl solution the concentration of the hydrogen ions, [
H
+
]
, is 0.00050 moles/liter (i.e. 0.025 M).
The pH is defined as −
log
[
H
+
]
.
Substituting 0.00050 into the equation for pH we find that the 0.00050 M HCl solution has a pH of -log(0.00050) = 3.30.
Answer:
Is there a picture To go with this?
Explanation:
Answer:
a)1.404 E-10 m^2/s
b)1.438 E-12 m^2/s
Explanation:
Diffusion Coefficients can be calculated at different temperatures taking into account the energy of the diffusive process, remember that this process takes place in the interstices of the solid, and gets with higher temperatures due to the higher kinetic energy of the particles.
a) For α-iron (BCC)
b) For γ-iron (FCC)
Explanation:
plzz tell me the ans even i also want to know plzzzz someone say ans
Answer:
4) 1.5 mol
Explanation:
Well, the equation is already balanced and the mole to mole ratio of reactants and products are all 1. So if the limiting reactant is HCl and you have 1.5 mol, you do the mole to mole ratio with NaCl and since it is 1 to 1, there'd be 1.5 mol of NaCl.
