Interpretation:
Whether the species
Concept introduction:
The magnetic properties of a substance are determined by examining electronic configuration of the species. Paramagnetic species are those in which unpaired electrons are remain in the orbital of any subshell and diamagnetic species does not contain unpaired electrons in the orbital of any subshell that means all electrons are paired.

- If we are talking about viscoelastic modulus or viscoelastic relaxation modulus in polymers, indicate the correct option.(A). It reports the variation of elastic behavior as a function of time.(B). It is only useful for defining its glass transition temperature.(C). It only allows us to define the polymer degradation temperature.(D). Neither option is correct.arrow_forwardWhen natural light falls perpendicularly on a material A, it has a reflectivity of 0.813%. Indicate the value of the refractive index.arrow_forwardIn piezoelectricity and piezoelectric ceramics, one of the following options is false:(A). Piezoelectricity allows an electrical signal to be transformed into a mechanical one.(B). PbZrO3 is a well-known piezoelectric ceramic.(C). Piezoelectricity and ferroelectricity in general have no relationship.(D). One of the applications of piezoelectricity is sonar.arrow_forward
- (30 MARKS) Give the major product(s ) formed including relevant stereochemistry or the complete reaction conditions for the following reactions. More than one step may be required for each reaction arrow, in which case the steps must be numbered 1), 2) etc. (2 marks each box) h) i) h) OH i) HO H3PO4, heat 2 Brarrow_forwardNonearrow_forwardIndicate which option is false(A). Resistivity has a residual component and a thermal component.(B). In some materials resistivity increases with T and in others it decreases.(C). In insulating materials, resistivity is very low.arrow_forward
- In ceramic materials, in relation to polymorphism, the same substance crystallizes differently when external conditions vary. Is this correct?arrow_forwardIndicate the type of bond that is considered to be a hydrogen bond.(A). Permanent dipole-dipole interaction between polar molecules.(B). Mixed ionic-covalent bond.(C). Principal interatomic bond(D). Van del Waals forces.arrow_forwardRetro aldol: NaOH H₂O H NaOH & d H₂O Harrow_forward
- Draw the product of the reaction shown below. Ignore inorganic byproducts. H conc. HBr Drawing Qarrow_forwardCalculate the atomic packing factor of diamond knowing that the number of Si atoms per cm3 is 2.66·1022 and that the atomic radii of silicon and oxygen are, respectively, 0.038 and 0.117 nm.arrow_forwardA pdf file of your hand drawn, stepwise mechanisms for the reactions. For each reaction in the assignment, you must write each mechanism three times (there are 10 reactions, so 30 mechanisms). (A) do the work on a tablet and save as a pdf., it is expected to write each mechanism out and NOT copy and paste the mechanism after writing it just once. Everything should be drawn out stepwise and every bond that is formed and broken in the process of the reaction, and is expected to see all relevant lone pair electrons and curved arrows.
