What is the biological advantage (in kj per mole of energy released as heat) of complete aerobic oxidation compared with anaerob
Elan Coil [88]

Aerobic respiration is the reaction of the compound or reactant in presence of oxygen whereas anaerobic respiration indicates the non availability of oxygen.

Aerobic respiration, responsible for the production of ATP slowly. It helps in breaking glucose molecule to CO_2, and result in production of 38 ATP.  

Whereas, anaerobic respiration break glucose molecule into two molecule of pyruvate. Glycolysis  only releases two ATP per glucose. The anaerobic process occurs rapidly such as it lets the tissues and muscles to receive the energy for short durational activity.



This increase in production of energy explains the reason for domination of aerobic organisms on earth which helps in organisms to grow in size with multicellular system and great diversity

The quantity of antimony in a sample can be determined by an oxidation-reduction titration with an oxidizing agent. A 6.33-g sam
daser333 [38]

Answer:

Explanation:

BrO3- (aq) + Sb^3+ (aq) --------> Br^3- (aq) + Sb^5+ (aq) is an unbalanced equation and needs to be balanced

BrO3- (aq) → Br^3- (aq

to balance it water must be added to the right side and H⁺ be added to the left side

BrO₃⁻ + 6 H⁺ + 8e⁻ → Br³⁻ + 3 H₂ O

Sb³⁺ (aq) → Sb⁵⁺ + 2e⁻

multiply the second equation by 4

BrO₃⁻ + 6 H⁺  + 8e⁻ → Br³⁻ + 3 H₂ O

4Sb³⁺ → 4Sb⁵⁺ + 8 e⁻

add the two equation together and cancel the 8 e electrons on both side

BrO₃⁻ + 4Sb³⁺ + 6 H⁺  → Br³⁻ +  4Sb⁵⁺ + 3 H₂ O

number of mole of BrO₃⁻  = volume in liters × molarity  = (29.9 / 1000) L × 0.120 M = 0.003588 moles

from the balanced equation of reaction;

one mole of BrO₃⁻  requires 4 moles of Sb³⁺

0.003588 moles of BrO₃⁻  will require = 0.003588 × 4 = 0.0144 moles of Sb³⁺

a) amount of antimony in grams in the sample =  0.0144 moles × 121.8 g ( molar mass of antimony) = 1.748 g

b ) percentage of antimony in the ore = 1.748 g / 6.33 g = 27.62 %

Compare uniformitarianism with catastrophism
wolverine [178]
Catastrophism is a theory that stated that earth was shaped by a suddentmassive violent events that happened within a short period of time.
Uniformitarianism, on the other hand, is a theory that stated earth was shaped by slow and gradual events over a long period of time, which could take millions of years.
