Answer:
The equinoxes are the only time when both the Northern and Southern Hemispheres experience roughly equal amounts of daytime and nighttime. On Earth, there are two equinoxes every year: one around March 21 and another around September 22.
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.
<u>Answer:</u> The moles of chlorine gas produced is 5.5 moles
<u>Explanation:</u>
We are given:
Moles of HCl = 11 moles
For the given chemical reaction:

By Stoichiometry of the reaction:
4 moles of HCl produces 2 moles of chlorine gas
So, 11 moles of HCl will be produced from
of chlorine gas
Hence, the moles of chlorine gas produced is 5.5 moles
