The length of this wire in meters= .016
The balanced chemical reaction is:
<span>Mg(OH)2 + 2HCl
--> MgCl2 + 2H2O</span>
So we can see that 2 moles of HCl reacts for every 1 mole
of Mg(OH)2.
moles HCl left = 0.125 M * 0.150 L – (0.125 M * 0.040 L) *
2
moles HCl left = 0.00875 mol
So the concentration of H+ ion is:
[H+] = 0.00875 mol / (0.150 L + 0.040 L)
[H+] = 0.046 M
So the pH is:
pH = - log 0.046
<span>pH = 1.34</span>
The answer is A the product of the pressure and volume
Rocks with GAPS AND CRACKS weather more quickly than rocks with smooth surfaces. Rocks without minerals more quickly than rocks MADE UP of many minerals.
