1.0006 moles O2
To solve for moles to grams, you use the molar mass (from the periodic table, so for oxygen it is 15.999 grams) to solve for moles this you set up the equation like this:
Oh wyeah wowiwiw and the girls are going
Answer:
See the image below
Explanation:
To draw a Lewis structure of a molecule, you place the least electronegative atom (Xe) as the central atom, with the more electronegative atoms (O) surrounding it.
Then you distribute the electrons around the atoms, giving every one an octet and placing any extra electrons on the central atom.
This procedure gives you four possible Lewis structures, so the actual structure is a resonance hybrid of them all.
Structure D has no formal charges, so it is the major contributor.
Answer:
increased only 6 percent
Explanation:
The six pollutants regulated under the Clear Air Act increased only 6 percent between 1970 and 2001, while energy consumption increased 42 percent.
<span> An object with a high specific heat would change temperature more slowly than one with low specific heat. Water, for example has a very high specific heat so it requires a lot of energy to heat it up. It also takes a while for water to cool down because it holds that heat for a long time. <3</span>
