A collection of monomers combines to form a polymer
Hope my answer helped! :D
Potassium Hydroxide (KOH) when added to the solution would give the highest pH
Explanation:
Bases or Alkali are associated with high pH while Acidic substances are represented by lower pH value.
In the given option
HCl- is a strong acid hence would have pH less than 7
H2SO4- also an acid with a pH less than 7
KOH- base with a pH higher than 7
H20-neutral compound with pH as 7
KOH is a very strong base and dissociates in aqueous solution to give it's corresponding metallic ion and hydroxyl ions (OH-) which are characteristic property of any base.
Answer:
Explanation:
We'll assume there is an excess of silver nitrate, so that all 12.0 moles of the magnesium (Mg) will react.
The balanced equation tells us we'll obtain 2 moles of Ag for every 1 mole of magnesium, for a molar ratio of 2/1.
Starting with 12.00 moles Mg, we would therefore hope to find twice that, or 24.00 moles of Ag.
To convert to grams, find the molar mass of Ag from the periodic table.
Ag has a molar mass of 107.9 (to 4 sig figs) grams/mole.
(24.00 moles)*(107.9 grams/mole) = 2590 grams (4 sig figs)
Hands off, it's mine.
