Hello.
<span>In a molecule, one mole of the molecule contains Avagadro's number of molecules.
So we can safely say that 0.788 moles of NaOH contain 0.788*Av. (Where Av is Avagadro's number)
And in a molecule of NaOH there are 3 atoms, so we multiply the number of molecules by 3 to obtain the number of atoms
3x0.788xAv
=3x0.788x6.02x10^23
=1.42x10^24 Atoms.
Have a nice day

Answer:
A) In aldehydes, the carbon is always joined to at least one hydrogen atom.
Explanation:
Aldehydes and Ketones are organic compounds.
The main difference between them is that aldehydes have the carbon atom attached to at least one hydrogen atom.
In ketones, the carbon is attached to another carbon.
- The IUPAC names of alkanals usually end with -e
- For alkanones usually end with -one
To reiterate, the striking difference between the two families is that in alkanals, a hydrogen atom is directly attached to the carbonyl group while in alkanones, no hydrogen atoms is attached to the carbonyl group but two bulky alkyl groups.
Answer:
Iron gains three electrons.
‘2’AgNO3 + Cu -> Cu(NO3)2 + ‘2’Ag
If it goes from a volume of x, then when the volume is doubled it will go to a volume of 2x. If you meant what happens to the pressure, then the pressure halves as volume doubles due to Boyle's law.
