Answer:
B
Explanation:
I know im right I forgot some of the lessons cause this was still in grade 3 now Im grade 6....
<span>100 g of KClO3 @ 122.55 g/mol = 0.816 moles of KClO3
by the reaction
2 KClO3 --> 2 KCl & 3 O2
0.816 moles of KClO3 @ 3 moles O2 / 2 moles KClO3 = 1.224 moles of O2 can be made
using molar mass
1.224 moles of O2 @ 32.0 g/mol =
39.2 grams of O2 can be made</span>
Ag+CuSO4
Silver is lower than copper in the electrochemical series and therefore would not displace it in any reaction.
Answer:
This is
1 mole = 18 gram = 6×10^23 molecules
1 gram = ?
1 gram= 18/6×10^23 atoms
1 gram =3×10^-23 atoms
2HCL + __ Zn --> ZnCl2 + H2
i think that's right, not exactly sure.
