Over the years, the thermite reaction has been used to ignite solid fuel rocket motors. Fe2O3 (s) + 2Al(s)
2Fe() +
Al2O3 (s)
The reaction of 0.3150_mol of Iron (III) Oxide with 16.89 g of solid Aluminum produces 0.05412 lb of
Fe. Find the limiting reactant, theoretical yield (in g), and percent yield.
(14 pts)
(Fe = 55.845 g/mol Al = 26.9815 g/mol 0 = 15.9994 g/mol) (1 lb = 453.59 g)

An observation that requires measurement is called quantitative observable or qualitative

Answer asap need it by wednesday morning carry out the following calculations on ph and ka of from data. i. calculate the ph of 0.02m hcl ii. calculate the ph of 0.036m naoh iii. calculate the ph of 0.36m ca(oh)2 iv. calculate the ph of 0.16m ch3cooh which has ka = 1.74 x 10-5 mol dm-3 v. calculate ka for weak acid ha which has a ph of 3.65 at 0.30m concentration vi. calculate the ka of a solution made by mixing 15.0 cm3 0.2m ha and 60.0 cm3 0.31m a-. [ph= 3.80] vii. calculate the ph of a solution made by mixing 15.0 cm3 0.1m naoh and 35.0 cm3 0.2m hcooh. [ka = 1.82 x 10-4 m]

Suppose you mix one mole of sulfuric acid (h2so4) with 1 mole of sodium hydroxide(naoh). why does the ph of the solution remain below 7? ( explain so i can get better understanding! )
