How many bonding electrons are in the lewis structure of carbon monoxide, co?
2 answers:
Answer:
6
Explanation:
The Lewis structure represents the valence electrons at the atoms, which ones are shared and the lone pairs. Carbon is at group 4 at the periodic table, and so has 4 electrons in the valence shell; oxygen is at group 6, and so has 6 electrons at the valence shell.
That compound is an exception of the octet rule. A triple bond is done between the atoms, and so, 3 electrons of carbon are shared and 3 electrons of oxygen are shared. Thus, there are 6 bonding electrons, as shown below in red.

Answer:
8.60 * atoms N2
Explanation:
We want to convert grams to moles and then moles to atoms.
First, we convert grams of nitrogen gas (which is N2) to moles. To do so, we need the molar mass of N2, which is just 14.01 * 2 = 28.02 g.
40 g N2 * = 1.43 mol N2
Now, we need to convert moles to atoms by using Avogadro's number, which is :
1.43 mol N2 * = 8.60 *
atoms N2
Thus, the answer is 8.60 * atoms N2.
