Selected Alkylating Agents Can Overcome Drug Tolerance of G 0-like Tumor Cells and Eradicate BRCA1-Deficient Mammary Tumors in Mice. Clin Cancer Res
First calculate for number of moles:
moles Ag = 12 g / (107.87 g / mol)
moles Ag = 0.111 mol
Convert to atoms using Avogadros number:
atoms Ag = 0.111 mol * (6.022 x 10^23 atoms / mol)
atoms Ag = 6.7 x 10^22 atoms
There are 47 electrons per atom, therefore:
Number of electrons = (6.7 x 10^22 atoms) * (47 electrons
/ atom)
<span>Number of electrons = 3.15 x 10^24 electrons</span>
Answer:
nitrate and sodium are spectator ions .The reactions that form an aqueous solution are often a spectator ions.
Answer:
Oxidation occurs at the anode: Fe(s) | Fe2+(aq) half cell. (ii) Reduction occurs at the cathode: Ag(s) | Ag+(aq) half cell. Oxidation occurs at the anode: Pt | Sn2+(aq), Sn4+(aq) half cell. (iii) Electrons flow from the anode to the cathode: from the Pt(s) → Ag(s) electrode.
