Potassium carbonate, K2CO3, sodium iodide, NaI, potassium bromide, KBr, methanol, CH3OH, and ammonium chloride, NH4Cl, are solub
just olya [345]
Answer:
A. K₂CO₃
Explanation:
The chemical reaction showing the ions produced on dissolving Potassium carbonate in water is:
K₂CO₃ ⇒ 2K⁺ + CO₃²⁻
Number of ions produced = 2 + 1 = 3
The chemical reaction showing the ions produced on dissolving sodium iodide in water is:
NaI ⇒ Na⁺ + I⁻
Number of ions produced = 1 + 1 = 2
The chemical reaction showing the ions produced on dissolving potassium bromide in water is:
KBr ⇒ K⁺ + Br⁻
Number of ions produced = 1 + 1 = 2
The chemical reaction showing the ions produced on dissolving ammonium chloride in water is:
NH₄Cl ⇒ NH₄⁺ + Cl⁻
Number of ions produced = 1 + 1 = 2
<u>The largest number of dissolved particles per mole of dissolved solute is produced by Potassium carbonate.</u>
The type of reaction that occurs without the addition of heat is called spontaneous reaction. That is option D.
<h3>What is spontaneous reaction?</h3>
Spontaneous reaction is defined as the reaction where by new substances are formed naturally without the addition of extra energy in the form of heat.
Therefore, the type of reaction that occurs without the addition of heat is called spontaneous reaction

Answer:
B. There is a very large percentage of C-12.
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to realize that, since the average atomic mass is 12.01 amu, then the C-12, with an atomic mass of 12.000 am prevails over C-13 with an atomic mass of 13.003 amu as long as the average is nearer to the former.
In such a way, the answer will be B. There is a very large percentage of C-12.
