Answer:
The nitration of phenol is easier than that of benzene because benzene has delocalised pie-electrons which makes it more stable than phenol.
Phenol is converted to Trinitrotoluene by adding zinc dust to remove the hydroxyl group, then reacted with Aluminium oxide followed by haloalkane.
Answer:
You can make the ramp really steep and hold the marble at the top of it
Explanation:
Answer:
The time recorded in the lab notebook is shorter than the true reaction time because the reaction starts the moment the two solutions were mixed
Explanation:
A chemical reaction is "a process that involves rearrangement of the molecular or ionic structure of a substance, as distinct from a change in physical form or a nuclear reaction" (Oxford dictionary).
A chemical reaction begins immediately the reactants are mixed together in a reaction vessel because the particles of the reactants immediately begin to collide with each other. There is no lost time before reactions begins!
This implies that, the time recorded in the lab notebook is shorter than the true reaction time because the reaction starts the moment the two solutions were mixed.
If the arrangement of atoms in a substance changes, then the overall chemical properties and reactivities of that particular substance changes as well.
1. 45.0 L H2S ( 1 mol / 22.4 L) ( 3 mol O2 / 2 mol H2S ) ( 22.4 L / 1 mol ) = 67.5 L O2 needed
2.<span>s- sphere, holds 2; p- dun bell, holds 6; d- complex, holds 10; f- very complex, holds 14
3.</span>In an ionic bond, oppositely charged ions are held together by the electronic force of attraction that exists between oppositely charged particles. In the ionic compound, anions and cations are present in a ratio that causes the total charge on the compound to be zero. Sodium phosphide, Na3 P, has three sodium ions for each phosphide ion. This ratio insures a zero total charge given the charges on the two individual ions (Na = 1+, P = 3-).
