Answer:
The part of the earth’s surface where, at temperatures below 32°F (0°C), the water is frozen solid. Even a small pond while frozen over during the winter is part of the cryosphere, but cryosphere refers more often to large regions covered in snow and ice for much or all of the year, as the ice sheets of Antarctica and Greenland, glaciers, icebergs, and expanses of permafrost, all of which are especially sensitive to global shifts in climate:
Explanation:
The Lewis structures for formate ion and carbon dioxide are shown in the attached pictures. As you can see, the formate ion consists of one C=O bond and one C-O bond, while carbon dioxide has two C=O bonds. Double bonds are weaker, hence, longer compared to single bonds. Therefore, the C-O bonds in the formate ion is shorter than those in carbon dioxide.
Answer:
-0.74
Explanation:
Let's consider the following redox reaction.
AgCl(s) + NO(g) → Ag(s) + Cl⁻(aq) + NO₃⁻(aq)
We can identify the oxidation and reduction half-reactions.
Reduction (cathode): 1 e⁻ + AgCl(s) → Ag(s) + Cl⁻(aq)
Oxidation (anode): 2 H₂O(l) + NO(g) → NO₃⁻(aq) + 4H⁺(aq) + 3 e⁻
The standard cell potential (E°) is equal to the difference between the standard reduction potential of the cathode and the standard reduction potential of the anode.
E° = E°red,cat - Ered,an = 0.22 V - 0.96 V = -0.74 V
