White is the answer to this
Answer:
To replicate DNA or to translate DNA to RNA, you need to unzip the double helix and create an exact replica of the code. To do this, the nitrogen bases are strictly paired, A to T or U and C to G. The ends of these molecules match each other in such a way that a hydrogen bond, a strong intermolecular force, can form only between matching bases. Special proteins travel up and down the DNA strand facilitating the copying of the genetic code into RNA so that it can be decoded to create proteins.

Answer:
3.97× 10²³ atoms of Ag
Explanation:
Given data:
Mass of Ni = 112 g
Mass of AgNO₃ = 112 g
Atoms of silver produced = ?
Solution:
Chemical equation:
Ni + 2AgNO₃ → 2Ag + Ni(NO₃)₂
Number of moles of Ni:
Number of moles = mass/ molar mass
Number of moles = 112 g/58.7 g/mol
Number of moles = 2 mol
Number of moles of AgNO₃:
Number of moles = mass/ molar mass
Number of moles = 112 g/169.87 g/mol
Number of moles = 0.66 mol
Now we will compare the moles of Ag with both reactants.
AgNO₃ : Ag
2 : 2
0.66 : 0.66
Ni : Ag
1 : 2
2 ; 2×2= 4 mol
Number of moles of Ag produce by AgNO₃ are less so it will limiting reactant and limit the yield of Ag.
I mole = 6.022 × 10²³ atoms
0.66 mol × 6.022 × 10²³ atoms / 1 mol
3.97× 10²³ atoms of Ag
Its either B or C. Its NOT A and D. I know that for a fact.
Hope this at least sorta helped. Have a good day! :D
