Answer:
Answers are bellow.
Explanation:
The element with electron configuration 1s22s22p63s1 belong I A group in the periodic table and it is sodium because it loses one electron.
We have periodic table in attachments.
Sodium is a chemical element with the symbol Na and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table, because it has a single electron in its outer shell, which it readily donates, creating a positively charged ion—the Na+ cation. Its only stable isotope is 23Na.
The free metal does not occur in nature, and must be prepared from compounds.
It is soft metal, reactive and with a low melting point.
Answer:
Found this off of google, "Henry's law comes into play every time a bottle of Pepsi (or any other carbonated drink) is opened. The gas above the unopened carbonated drink is usually pure carbon dioxide, kept at a pressure which is slightly above the standard atmospheric pressure."
Answer:

Explanation:
H₂O(ℓ) ⟶ H₂O(g)


Data:
T = 25 °C
ΔG° = 8.6 kJ·mol⁻¹
Calculations:
T = (25 + 273.15) K = 298.15 K

Standard pressure is 1 bar.

Answer:
The rate constant at T = 100 C is 1.0*10⁻³
Explanation:
The Arrhenius equation relates two rate constants K1 and K2 measured at temperatures T1 and T2 as shown below:

here, ΔHrxn = standard enthalpy change of the reaction
R = gas constant
From the given information:
K1 = 7.4*10^-4
T1 = 25 C = 25+273 = 298 K
T2 = 100 C = 100+273 = 373K
ΔH°=4.1kJ/mol

K2 = 1.03*10⁻³
