The noble-gas notation for tin (Sn) will contain the symbol

Tanzania [10]

The noble gas notation is as follows- you must start with the noble gas that is before the element which in this case is Krypton and then from there you continue the electron configuration as follows- [Kr] 5s^2 4d^10 5p^2

at which type of plate boundary do most earthquakes occur? A.convergent B.transform C.divergent D.trench

tino4ka555 [31]

Answer: A. convergent

Most earthquakes occur at the boundary where two plates meet. This phenomena is called as convergent plate tectonics. In this phenomena the two plates moves towards each other. If the plates are of equal density then they will push each other but if they are of unequal density, the denser plate sink beneath the other plate.

What is the free energy change if the ratio of the concentrations of the products to the concentrations of the reactants is 22.3

snow_lady [41]

The free energy change(Gibbs free energy-ΔG)=-8.698 kJ/mol

<h3>Further explanation</h3>

Given

Ratio of the concentrations of the products to the concentrations of the reactants is 22.3

Temperature = 37 C = 310 K

ΔG°=-16.7 kJ/mol

Required

the free energy change

Solution

Ratio of the concentration : equilbrium constant = K = 22.3

We can use Gibbs free energy :

ΔG = ΔG°+ RT ln K

R=8.314 .10⁻³ kJ/mol K

$\tt \Delta G=-16.7~kJ/mol+8.314.10^{-3}\times 310\times ln~22.3\\\\\Delta G=-8.698~kJ/mol$

The four major attractive forces between particles are ionic bonds, dipole-dipole attractions, hydrogen bonds, and dispersion fo

natima [27]

Answer with Explanation:

Ionic bond:It is that type of bond which formed between negative and positive ions.

Hydrogen bonding:Hydrogen bonding formed between hydrogen and high electronegative elements.

Dispersion force:It is weakest intermolecular force.It is temporary attractive force.When electrons of two adjacent atoms occupy positions that make the atoms temporary dipoles.

NaCl: In which Na is positive ion and Cl is negative ion.

Therefore, NaCl is ionic.

HF:F is highest electronegativ elements.

HF:Hydrogen bonding

HCl: Hydrogen bonding

$F_2$ :Dispersion
