Write an equation for the reaction of the Tollens reagent<br> withheptanal?
dangina [55]

Answer:

CH_3 CH_2 CH_2 CH_2 CH_2 CH_2 CHO + 2[Ag(NH_3)_2]+  3 H_2 O = CH_3 CH_2 CH_2 CH_2 CH_2 CH_2 COOH +2Ag + 4NH_3

Explanation:

Tollens test is carried out to perceive difference between aldehydes and ketones on the basis of their capability to oxidized easily.

when Tollens react with aldehyde (heptanal) , a silver mirror is form on inner side of container.

The reaction between tollens and heptanal is given as

CH_3 CH_2 CH_2 CH_2 CH_2 CH_2 CHO + 2[Ag(NH_3)_2]+ 3 H_2 O = CH_3 CH_2 CH_2 CH_2 CH_2 CH_2 COOH +2Ag + 4NH_3

. A 500.0 mL buffer solution contains 0.30 M acetic acid (CH3COOH) and 0.20 M sodium acetate (CH3COONa). What will the pH of thi
julia-pushkina [17]

Answer:

pH = 4.57

Explanation:

pH = pKa + log ([OAc⁺]/[HOAc])

Ka(HOAc) 1.8 x 10⁻⁵ => pKa = -log(1.8 x 10⁻⁵) = 4.74

[OAc⁻] = 0.20M

[HOAc] = 0.30M

pH = 4.74 + log([0.20]/[0.30]) = 4.47 + (-0.17) = 4.57

When a rain forest is slashed and burned, the local concentration of carbon dioxide in the atmosphere increases. This is primari
tiny-mole [99]

The local concentration of carbon dioxide in the atmosphere increases when rainforest is slashed and burned because there is less vegetation to use CO2 for photosynthesis.

<h3>WHAT IS PHOTOSYNTHESIS:</h3>
  • Photosynthesis is the process whereby green plants obtain their food (glucose) using energy from sunlight.

  • Green plants in an ecosystem absorb carbon dioxide (CO2) from the atmosphere as one of the reactants of photosynthesis.

Therefore, this means that the local concentration of carbon dioxide in the atmosphere increases when rainforest is slashed and burned because there is less vegetation to use CO2 for photosynthesis.
