Answer:
See the answer below
Explanation:
<em>Aqueous solution of copper II nitrate contains solute of copper II nitrate dissolved in water</em>. The equation for the reaction is as below:
+ 
--> 
Hence, the solute chemical is copper II nitrate while the solvent is water.
Chemical formula of copper II nitrate - 
Chemical formula of water - 
Answer:
Explanation:
Electron capture is a form of beta decay in which the nucleus of a radionuclide captures an electron. In the case of mercury-201, the equation below illustrates that
²⁰¹₈₀Hg + ⁰₋₁e ⇒ ²⁰¹₇₉Au
As can be seen above, the electron capture reduces the atomic number by one unit leading to the production of a new radioisotope (because of the change in atomic number).
Answer:
A. N₂(g) + 3H₂(g) -----> 2NH₃ exothermic
B. S(g) + O₂(g) --------> SO₂(g) exothermic
C. 2H₂O(g) --------> 2H₂(g) + O₂(g) endothermic
D. 2F(g) ---------> F₂(g) exothermic
Explanation:
The question says predict not calculate. So you have to use your chemistry knowledge, experience and intuition.
A. N₂(g) + 3H₂(g) -----> 2NH₃ is exothermic because the Haber process gives out energy
B. S(g) + O₂(g) --------> SO₂(g) is exothermic because it is a combustion. The majority, if not all, combustion give out energy.
C. 2H₂O(g) --------> 2H₂(g) + O₂(g) is endothermic because it is the reverse reaction of the combustion of hydrogen. If the reverse reaction is exothermic then the forward reaction is endothermic
D. 2F(g) ---------> F₂(g) is exothermic because the backward reaction is endothermic. Atomisation is always an endothermic reaction so the forward reaction is exothermic
Answer:
I dont speak this language sorry :(
Explanation:
The pairing that accurately matches a bio molecule polymer with its monomer subunit would be B. Protein and amino acids.
