Biology
1 answer:
Kay [80]3 years ago
8 0

Answer:

yes, gold can be created from other elements. The process requires nuclear reactions and is so expensive that currently it would cost a lot more than the price of natural gold available, therefore, unprofitable. Gold is the chemical element with 79 protons in each atomic nucleus. Every atom containing 79 protons is a gold atom, and all gold atoms behave the same chemically. In principle, gold can be created by simply assembling 79 protons, (and enough neutrons to make the nucleus stable).

You disrupt all hydrogen bonds in a protein. what level of structure will be preserved?
Alex777 [14]
I believe the primary structure will be preserved. The secondary level of proteins is defined by patterns of hydrogen bonds between the main chain peptide groups. Therefore distorting the Hydrogen bonds disrupts the secondary structures. The primary structure on the other hand is not affected by disruption of the hydrogen bond since these structures refers to the sequences of amino acids in the polypeptide chains that are joined by the peptide bonds.

How many grams of CaCl2 are in 0.75M solution with a volume of 1L
grandymaker [24]

83.235 grams of CaCl2 is required to make 1 litre of 0.75M solution.

Explanation:

Molarity or molar concentration is the number of moles of solute that can be dissolved in 1 L of a solution.

let us find the number of moles

n=C*V                Concentration is 0.75M

                          Volume is 1000ml.

n= 0.75*1

n= 0.75

This means there are 0.75 moles of CaCl2 in 1000 ml of solution of .75M.

Molar mass of CaCl2 is = 40.08+ 2(35.5)

                                       =   110.98 gms

Thus 1 MOLE OF CaCl2 weighs 110.98

         so 0.75 moles will weigh  110.98*0.75

                                              =  83.235 grams of CaCl2 is required to make 1 litre of 0.75M solution.
