Answer:
= 
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
= 
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
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.
