Answer:
Option C. Gain 1 electron
Explanation:
Valence electron(s) are the electron(s) located on the outermost shell of an atom. Valency is simply defined as the combining power of an atom.
Chlorine (Cl) atom has 7 valence electron. This implies that Cl needs just one electron to complete it's octet configuration. It will be difficult for Cl to lose any of it's valence electron(s). Cl can either gain or share 1 electron to become stable.
Thus, considering the options given in the question above, option C gives the correct answer to the question.
<h3><u>Answer;</u></h3>
357 mg/mL
<h3><u>Explanation;</u></h3>
- Solubility is defined to be the maximum amount of solute that will dissolve in a given amount of solvent at a specific temperature. The solubility of a salt is one of many physical properties that depend on temperature.
- At room temperature 25 °C, the solubility of salt or Sodium Chloride is 357 mg/mL.
- For many solutes, increasing the temperature increases the solubility of the solute. The solubility of sodium chloride or table salt is only slightly affected by temperature increase.
Answer:
The answer to your question is 0.33 liters
Explanation:
Data
Volume = ?
Molarity = 1.5 M
number of moles = 0.5
Formula

Solve for V

Substitution

Simplification and result
Volume = 0.33 l
X:5.8g=16:(23+1+12+3*16)
x:5.=16:84
x:=5.8* 16/84
this is approximately 1.1
