To solve this problem we use Boyle's law to correlate the varying volume and pressure at constant temperature. Assuming ideal gas law, we use the equation P1/V1= P2/V2. Substituting, 735 mm Hg/ P2= 63.5 ml/69.2 ml. P2 is equivalent thus to 800.97 mm Hg.
Answer:
This is
1 mole = 18 gram = 6×10^23 molecules
1 gram = ?
1 gram= 18/6×10^23 atoms
1 gram =3×10^-23 atoms
There must be two oxygen atoms to form covalent bond as when each oxygen atom contribute 4 electrons to the another, the atoms will become stable as they both have 8 electrons on the outermost shell. Refer to the dots and cross diagram i drew.
One molecule of nabh4 will reduce only two molecules of m-acetylbenzaldehyde to form the corresponding product because there are only two functional groups that can react with NaBH4, namely the ketone and the aldehyde, but NaBH4 had four H present to protonate the molecule.
What is protonation?
An atom, molecule, or ion can be protonated by adding a proton to it. The difference between protonation and hydrogenation is that during protonation, the protonated species' charge changes, whereas it remains unchanged during hydrogenation. Numerous catalytic processes result in protonation.
A conjugate acid is created when a proton (or hydron, or hydrogen cation), (H+), is added to an atom, molecule, or ion. Deprotonation is the analogous process that occurs when a proton is taken out of a Bronsted-Lowry acid.
