Answer:
Explanation:
Hello,
In this case, since the neutralization reaction between HCl and NaOH is:
We notice a 1:1 molar ratio, for that reason, at the equivalence point we find:
Thus in terms in molarities one could compute the concentration of HCl in the old bottle for the used NaOH for the neutralization as:
This value is lower than 37% HCl that in molarity is about 12 M, such difference is due to its high volatility.
Best regards.
Answer: Option (D) is the correct answer.
Explanation:
Atomic number of lithium is 3 and electrons in its shell are distributed as 2, 1. Atomic number of chlorine is 17 and electrons in its shell are distributed as 2, 8, 7.
Thus, we can see that lithium has 1 extra electron and chlorine has deficiency of 1 electron. Therefore, in order to gain stability lithium will transfer its 1 extra electron to chlorine atom.
Thus, we can conclude that electrons are transferred from the lithium atom to the chlorine atom.
Answer:
Chemically, table salt consists of two elements, sodium (Na) and chloride (Cl). Neither element occurs separately and free in nature, but are found bound together as the compound sodium chloride.
Explanation:
please mark me brainliest.
Answer:When table salt is added to water the resulting solution has a higher boiling point than the water did by itself. The ions form an attraction with the solvent particles that then prevent the water molecules from going into the gas phase. Therefore, the salt-water solution will not boil at 100oC.Jun

Answer:
267.57 kPa
Explanation:
Ideal gas law:
PV = n RT R = 8.314462 L-kPa/K-mol
P (16.5) = 1.5 (8.314462)(354) P = 267.57 kPa
