The larger the piece the longer it will take to break down. This is because it has more mass that needs to be broken down.
Total weight = 1 + 35.45 + 3 * 16 = 84.45
H = 1 / 84.45 * 100% = 1.18%
Cl = 35.45 / 84.45 * 100% = 41.98%
O = 48 / 84.45 * 100% = 56.84%
Hi!
Magnets attract with opposite poles. The reason is the North pole of a magnet's magnetic lines (if that makes any sense) generally flow inwards, making it pulling in, and the South pole's magnetic lines flow outwards, pushing out. If you align two magnets with the same poles together, they will always repel, because they will be flowing in different directions.
However, if you align a north and a south pole together, they will work together, and attract.
Therefore, if you place two magnets randomly, and they're close enough, they'll align so that the north pole of one magnet faces the south pole of the other magnet, or choice A.
how u gonna expect someone to do all of that XD
Doing this increases the hydrogen ion consentration h+. when the acid is added to the water molecule constituting the acid HA is split into h+ and A- ions. The H + is produced this way combine with the H2O to form H3O+ or hydronium ions.
