Answer:
Fluorine = 7 v.e.
Sulfur = 6 v.e.
Oxygen = 6 v.e.
Nitrogen = 5 v.e.
Carbon = 4 v.e.
Explanation:
Valence electrons can be easily determined by understanding groups (columns). Every element in. . .
column 3A (13) = 3 v.e.
column 4A (14) = 4 v.e.
column 5A (15) = 5 v.e.
column 6A (16) = 6 v.e.
column 7A (17) = 7 v.e.
I'll give you three just in case a couple are ones you aren't quite looking for.
-Carbon has several allotropes, or different forms in which it can exist. A couple of allotropes included are graphite and diamond, which both have very different properties.
-Despite carbon's ability to make 4 bonds and its presence in many compounds, it is highly nonreactive under normal conditions.
-Carbon exists in three main isotopes: ¹²C, ¹³C, and ¹⁴C in which ¹⁴C is radioactive and used in dating carbon-containing samples (known as radiometric dating)
Hope this helps!!
Explanation:
Scientist performs experiments as a process in the scientific method.
Experiments are quantitative and deliberate efforts towards testing an idea.
- Scientists perform experiment in order to validate or invalidate a proof.
- Also have more insight about the observation.
- To test an idea
- To gather information about something.
- To advance the pool of knowledge about a claim

Not to be rude but its in there. Hope this helps
Explanation:
Chemical weathering changes the molecular structure of rocks and soil. For instance, carbon dioxide from the air or soil sometimes combines with water in a process called carbonation. This produces a weak acid, called carbonic acid, that can dissolve rock.

First, calculate the molar mass of Na2CO3 by looking up the molar mass of the elements used in it.
Sodium = 22.989769
Carbon = 12.0107
Oxygen = 15.999
Multiply each molar mass by the number of atoms used, and sum the results to get the molar mass
2 * 22.989769 + 12.0107 + 3 * 15.999 =105.9872
Finally, multiply the molar mass by the number of moles you need.
0.752 * 105.9872 = 79.7024 grams</span>
