OCR 2023 Chemistry A H032/02: Depth in chemistry AS Level Question Paper & Mark Scheme (Merged) (i) The uncertainty in each thermometer reading is ±0.5°C and the uncertainty in the measured volume of water is ±2cm3. Determine whether the temperature change or the measured volume of water has the greater percentage uncertainty - ANSpercentage uncertainty= (Absolute Uncertainty / Measured Value) x 100 uncertainty of measure volume of water= 2/200 x 100= 1 uncertainty of temp ris...

Molarity (M) - mols solute / L of solution Molality (m) - mols solute / kg solvent Freezing point depression / boiling point elevation deltaT(b) or deltaT(f) - deltaT(b or f) = i*K(b or f)*m i = Van't Hoff factor Kb or Kf = constant m = molality of solute Osmotic pressure (pi) - pi = i*M*R*T i = Van't Hoff factor M = molarity R = gas law constant 0.08206 L*atm/K*mol T = temperature (K) Van't Hoff factor (i) - i = mols of particles in solution / mols of solute dissolves applies fo...

If we plot the amount of Na2SO4 formed against the mols of NaOH added what does the intersection of the two regions indicate, and where is the intersection ~ the stoichiometric point representing where the point where amount of NaOH and H2SO4 are in stoichiometric proportions i.e neither are the limiting reagent(neither remain after reaction is complete) forms when 2 mols of NaOH forme 1 mol of Na2SO4 If we react 1 mol of H2SO4 with 1.8 mol of NaOH what is the limiting reagent? If ...

What is the osmolarity of a solution of 140 mM NaCl? 280 mOsm/L 140 mOsm/L 320 mOsm/L 0.0140 Osm/L 280 mOsm/L How much filtrate is produced in an hour in a typical person? 125 ml/min No idea. 7.5 L 12.5 L 7.5 L A transfusion of serum would differ from a transfusion of saline in that The number of red blood cells in the blood would decrease less with serum compared to saline. The hematocrit would increase after serum transfusion because formed elements are a part of serum but are not include...

The volume starts with three review chapters to set the scene. These cover the involvement of WT1 in pediatric cancer, kidney disease, and tissue development and homeostasis. These are followed by methods chapters, fi rstly on tools for studying developmental and cellular processes. These include chapters on cell marking and lineage tracing, epicardial cell methodology, colony forming assays for bone marrow stem cells, isolation of adipocyte progenitors using Fluorescence Activated Cell Sor...
