Consider the following chemical reaction. Mg(s)+Ni(NO3)2(aq)⟶Ni(s)+Mg(NO3)2(aq)
gogolik [260]

Answer:

The nickel(II) ion is the oxidizing agent .

Explanation:

The reaction given in the question is as follows -

Mg (s)  + Ni(NO₃)₂ (aq) ---- > Ni (s)  +  Mg(NO₃)₂ (aq)

From , the above equation , the change in oxidation state from the reactant t to the product is as follows -

  • Mg is 0 to +2 ,

Since ,

The oxidation state is increasing , this is  oxidation process .

and , Mg , is a reducing agent .

  • Ni⁺² is +2 to 0

Since ,

the oxidation state is decreasing , this is the reduction process .

and ,  Ni⁺² , is an oxidizing agent .

,

Hence , The correct statement is -

The nickel(II) ion is the oxidizing agent .

Snowcat [4.5K]

Answer:

Answer: There are 9 ways to make a single base mismatch, 27 ways to make a two base pair mismatch and, again, 27 ways to make a three base pair mismatch (and only 1 way to do it correctly). Q = e − U i k b T i ∑ = e − U zeromismatches k b T + 9 × e − U onemismatche k b T + 27 × e − U twomismatches k b T + 27 × e − U threemismatches k b T = e 0 k b T + 9 × e − 10 kJ / mol k b T + 27 × e − 20 kJ / mol k b T 27 × e − 30 kJ / mol k b T = 1 + 9 × (0.018) + 27 × (0.00033) + 27 × (0.000006) = 1 + (0.163) + (0.0089) + (0.00016) =1.17 p 0 = e − U 0 k b T Q = e − 0 k b T 1.17 = 1 1.17 = 0.853 => 85.3% Therefore, approximately 85.3% of all amino acids are translated faithfully. The redundancy built into the genetic code and other energetic considerations raise this number considerably.

What is the molar mass of barium hydroxide
maksim [4K]

Answer:

171.34 g/mol

Explanation:

Ba molar mass = 137.328 g/mol

O molar mass = 15.999 g/mol * 2 = 31.9980 g/mol

H molar mass = 1.008 g/mol * 2 = 2.0160 g/mol

137.328 + 31.9980 + 2.0160 = 171.3420 = 171.34 g/mol
