The shape of a protein molecule resembles BEADS ON A STRING.
Proteins are macro molecules that are formed from amino acids. There are different types of amino acids, thus, different amino acids combine together to form different types of protein. This means that, proteins are formed from sequences of amino acids; they are long chains of different amino acids, that is why, they are likened to beads on string.
The structures of proteins are in three dimensions, they are primary, secondary and tertiary structures. The primary structure refers to the sequence of the amino acids in a protein. The amino acids in the primary structure are linked together by peptide bonds.
Oil spills, trash dumping, and sludge dumping are the sources of point- source pollution
The answer is 814.5 :
There is 3258 calories in one pound of margarine (according to google)
one-fourth= 0.25
0.25*3258= 814.5 calories
Answer:
0.050 mol
Explanation:
The reaction that takes place is:
Then we convert 0.050 moles of phosphoric acid into moles of ammonium phosphate, using the stoichiometric coefficients of the reaction:
- 0.050 mol H₃PO₄ *
= 0.050 mol (NH₄)₃PO₄
Thus, the complete reaction of 0.050 moles of phosphoric acid would produce 0.050 moles of ammonium phosphate.
