3. Draw the line angle structure for the following condensed formulas: H3CCH2CH(OH)CH2C(CH3)2CH3 H3CC(CH2CH2CH3)2CH2COCH2CH(CH3)2

draw the alkane strucutre based off the IR spectrum, 1H NMR spectrum, and 13C NMR spectrum for this compound.

Determine the indices for the directions shown in the following cubic unit cell: A B D +y +x -/2

Match the structure

6 x 10⁻⁵¹ = (0.15 M)² [S²⁻] [S²⁻] = (6 x 10⁻⁵¹) / (0.15 M)² Calculating, we find the minimum concentration of sulfide ion required: [S²⁻] ≈ 2.7 x 10⁻⁴⁹ M. check it calcution is write

What is the free Cu2+ (ag) concentration in a solution made up by mixing 50.0 mL of 0.100M Cu(NO3)2 with 50.0 mL 1.00 M NH3 (aq)? Given: Cu2+ (ag) + 4 NH3 (aq) > < Cu(NH3)42+ (aq) K, = 1.1 x 10^13

B, C The equations are in the other page. Thanks

Give the IUPAC name for each structure. Part 1 of 3 CH3(CH2)2CO2CH2CH3 Part 2 of 3 Part 3 of 3 -CO₂-CH2-CH3 G G G

Balance the following equations: a, b, c, d, & e Please explain thoroughly how and why I would get the balanced numbers properly. If you're going to handwrite it, please write neatly. Please use vertical, diagonal, and horizontal lines/boxes to determine the balance and cross out the number that is not needed; for example:  C 8 8 H 3 5 O 5 2

Please write the structures of alginic acid and acrylic acid(just show the repeating unit structure). Please explain what is the behaviour of alginic acid and acrylic acid hydrogel, whenyou increase the Ph? (increasing beyound 7)
