It means it will only allow some to go through but not all.
From the Avogadro's law one mole of a substance contains 6.022× 10^23 particles.
Therefore; 1 mole of water contains 6.022 × 10^23 molecules
Hence 1.7 moles will contain;
1.7 × 6.022 × 10^23 molecules
= 10.2374 × 10^23 molecules
= 1.024 ×10^24 molecules
≈ 1.02 × 10^24 molecules
Answer:
See figure 1
Explanation:
For this question, we have to remember that in the lewis structures all atoms must have<u> 8 electrons</u>. And each atom would have a different value of <u>valence electrons</u>:
Carbon => 4
Oxygen=> 6
Hydrogen=> 1
Additionally, for the <u>hybridizations</u> we have to remember that:
=> 4 single bonds
=> 1 double bond
=> 1 double bond
With this in mind, the formaldehyde and formic acid would have carbons and the ethanol an carbon.
Finally, for the oxidation state. We have to remember that <u>if we have more bonds with oxygen, we will have more oxidation</u>. Therefore, the carbon that has more oxidation is the one in the formic acid (we have several bonds with oxygen).
See figure 1
I hope it helps!
Two electrons because it is in second group.
