Freshwater on the land surface is a vital part of the water cycle for everyday human life. On the landscape, freshwater is stored in rivers, lakes, reservoirs, and creeks and streams. Most of the water people use everyday comes from these sources of water on the land surface.
Yes, all Bronsted-Lowry bases are Lewis bases, however no longer all Lewis bases are Bronsted-Lowry bases.
<h3>What is a susceptible Brønsted-Lowry bases?</h3>
A susceptible Brønsted-Lowry base indicates very little tendency to acquire a proton.
Weak Brønsted-Lowry bases consist of H2O, Cl- and NO3-. For example, the chloride ion is a vulnerable Brønsted-Lowry base:
<h3>What is the distinction between a Brønsted-Lowry base and a Lewis base?</h3>
Whereas the Brønsted-Lowry and the Arrhenius classifications are primarily based on switch of protons, Lewis acidity and basicity are primarily based on the sharing of an electron pair. Lewis acids can be given an electron pair, whilst Lewis bases can donate an electron pair.

Answer:
Molecular mass of BHT is 204,2 g/mol
Explanation:
To answer this question you need to know that Freezing-point depression (A colligative property) is the decrease of the freezing point of a solvent on the addition of a non-volatile solute. The formula is:
ΔT = Kf m
Where ΔT is the freezing point depression (5,5°C - 4,880°C = 0,62°C
Kf that is freezing point molar constant of the solvent (5,065°C/m)
And m that is molality (moles of solute/kg of solvent). Replacing:
Knowing you have 100,0g of solvent ≡ 0,1000 kg:
=<em> 0,01224 moles of solute </em> <em>≡ BHT</em>
As grams of BHT are 2,500, molecular mass of BHT is:
<em>204,2 g/mol</em>

Electron affinity is the energy released when an electron is added to the gaseous atom or ion.
Electron affinity increases by moving from left to right in periodic table and decreases by moving from up to down.
So the correct answer is Te
Xe: being as noble gas it is unacceptable to gain an electron
The values of electron affinity for these elements:
Ba (13.9 kJ/mol) - Te (190.1 kJ/mol) - Xe (-80 kJ/mol) - Cs (45.5 kJ/mol)
