combustion reaction are always exothermic in nature...so heat liberated is one of way to identify it
Urban development has been linked to many environmental problems, including air pollution, water pollution, and loss of wildlife habitat. Urban runoff often contains nutrients, sediment and toxic contaminants, and can cause not only water pollution but also large variation in stream flow and temperatures.
Oxidation number of Cl in chlorate ion ClO3- is +5
Answer:
III. Fatty acids are less oxidized than carbohydrates
Explanation:
Both triglycerides and glycogen may be used to obtain energy, this is:
- Triglycerides through the B-oxidation, where a molecule is first activated and entered into mitochondria matrix, to be degraded (oxidized)
- Glycolysis, where a molecule of 6 carbons is splitted in 2 components of 3 carbons each (pyruvate)
As an energy reserve substance, triglycerides have 2 main advantages, compared with glycogen:
1) From the chemical point of view, triglycerides have a more reduced state than glycogen (this is, have more atoms of hydrogens), hence these molecules give twice energy than glycogen
2) As triglycerides are hydrophobic molecules, they remain in an anhydrous form (unlike glycogen, which is hydrophilic), and this makes easier to move these molecules to obtain energy
