The cofficent is 2 for diphosphorus trioxide
The question is incomplete: the complete question is:
Rank molecules or group of molecules by when mammals use as fuel, starting right after meal to only through?
starvation.
a) glucose from glucose-2-phosphate from glycogen.
b) free glucose and amino acids
c) fatty acids from triglycerides
d) glucose produced from amino acids in liver.
Answer:
B
A
C
D
Explanation:
Free glucose and amino acid enters into the blood stream directly and can be used immediately after meals by mammals.
The liver stores excess glucose as glycogen, hence when glucose levels begin to reduce in the body, the pancreas releases glucagon which converts glycogen to glucose.
Triglycerides are broken down to give fatty acids which gives much more energy than glucose.
During starvation, amino acids in the liver is converted to glucose when a person goes for days without eating.
Answer:
The correct option is: (D) would function as both an acid and a base
Explanation:
A carbon skeleton bonded to a amino group as well as a carboxyl group, will behave as an acid in basic medium and base in acidic medium. This is because the carboxyl group present in the compound will release a proton in basic medium and the amino group will accept a proton in the acidic medium.
<u>Therefore, a carbon skeleton which is covalently bonded to a carboxyl and amino group will behave as both acid and base.</u>
Answer:
Strontium (St)
Explanation:
The atom that will have a larger radius than zinc is strontium, Sr.
Atomic radius is defined as the half of the inter-nuclear distance between two covalently bonded atoms of non-metallic elements or half of the distance between two nuclei in the solid state of metals.
- Across the period atomic radii decreases progressively due to the increase in nuclear charge.
- Down a group atomic radii increase progressively due to the successive shells of electrons being added.
- Since strontium satisfies the criteria, it has the larger atomic radius.
Answer: The precipitate formed is 
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid or precipitated form are represented by (s) after their chemical formulas.
A double displacement reaction in which one of the product is formed as a solid is called as precipitation reaction.
The balanced chemical equation is:
