Explanation To record the given data Concentration of NaOH is 0 .167M in 500mL Concentration of HCOOH is 0 .100M in 500mL The given data is recorded as such. To calculate moles of NaOH and HCOOH M o l e s N a O H = 0.500 L × 0.167 m o l 1 L = 0.0835 m o l M o l e s H C O O H = 0.500 L × 0.100 m o l 1 L = 0.0500 m o l The number of moles of NaOH and HCOOH is calculated by converting given moles to one litre. To calculate concentration of Na + , HCOO - , OH - , H + HCOOH ( aq ) +NaOH ( aq ) → HCOONa ( aq ) +H 2 O ( l ) Initial concentration ( mol ) : 0 .0500 0 .0835 0 Change in concentration ( mol ) : -0 .0500 -0 .0835 +0 .0500 Final concentration ( mol ) : 0 -0 .0335 0 .0500 The total volume of solution is 1L(500 mL+500 mL=1000 mL) [OH - ] = 0 .0335 mol 1 .00 L = 0 .0335 M [Na + ] = (0 .0335 + 0 .0500) mol 1 .00 L = 0 .0835 M [H + ] = K w [OH - ] = 1 .0 × 10 -14 0

sketch the nature of the metal-alkylidene bonding interactions.

Part C The perspective formula of isoleucine, an amino acid, is provided below. HOOC H₂NIC H 川 CH3 CH,CH3 Draw the Newman projection in staggered conformation for isoleucine by viewing the molecule along the C-2-C-3 bond. 1. Edit the Newman projection on the canvas. 2. Replace the appropriate hydrogens with the appropriate -CH3 or other groups. 3. If you need to start over, Undo or choose a Newman projection from the Templates toolbar (bottom). Important: Never delete the hydrogen atoms or bonds directly attached to the template, and do not move them by dragging or dropping them. That will break the projections structures. Only replace them! ▸ View Available Hint(s) 0 2 H± 3D EXP. L ד י CONT. 2 H 0 N о
