The anwer roght here is the last one d. 0.0556 mol. The next procedure says why this is right:
<span>3.35 x 10^22 atoms x (1 mol / 6.02 x 10^23 atoms) = 0.0556 mol
</span>
I hope this can help you greatly

It is true that enzymes in the digestive tract catalyze hydrolysis reactions.
Answer:
Explanation:
Materials used for sacrificial anodes must be relatively pure active metals.
Or we can say any metal with more negative potential that that of iron ( +0.59) is used for sacrificial anode for iron
so from the above the following can be used as sacrificial anode for iron
Mg = +1.06
Al = +0.96
Zn = +0.7
The following will not be used as sacrificial anode for iron because their negative reduction potential is less than that of iron ( +0.59)
Ag = -0.76
Cu = -0.44
Pb = 0
Sn = +0.34
Au = -3.05
In water because they separate into charged ions, which are then attracted to the oppositely charged electrode. Hope you have a great day!!
