Suppose Milk of Magnesia is a suspension of magnesium hydroxide in water. A common medicine, it is frequently used as an antacid for the reason that it neutralizes hydrochloric acid in the stomach:
Mg(OH)2(s) + 2 HCl(aq) ? Mg2+(aq) + 2 H2O(l)
Compute the mass of HCl that is neutralized by 0.9 g of Mg(OH)2(s).
when 12.1g of the sugar sucrose a non-electrolyte are dissolved in exactly 800g of water the solution has a freezing
Compute the solubility of silver sulfite, Ag 2 SO 3 in units of grams per liter and complete and balance these given redox equations by the half reactions method (the oxidation reaction and the reduction reaction)
Why is the E isomer of 1,2-dibenzoylethylene more stable than the Z isomer. is this why irradiation goes from E to Z and not the other way around. also discuss polarity differences between the two isomers.
