NH₄⁺ - ammonium cation
S²⁻ - sulfide anion
(NH₄)₂S - ammonium sulfide
The answer is A.
Answer:
yes.
Explanation:
Energy transfer will continue until the objects are at the same temperature. There are 3 ways in which thermal energy can be transferred from one object/substance to another, or from a system to its surroundings: Conduction. Convection.
The standard curve was done at the wavelength of 362 nm for uniformity. We can use this function to determine the concentration at any absorbance value. At A = 0.782, c is,
<span>A = (3.2 x 10^-1 M^-1)c
0.782 = </span><span>(3.2 x 10^-1 M^-1)c
c = 2.44 M
The concentration of the triiodide solution is 2.44 M.</span>
The most important factor would be the number of electrons of the compound. Compounds need to achieve electron configuration the same as the noble gas. Noble gases are the most stable elements in the periodic table. Hope this answers the question.
