Question
Chapter 22, Problem 22.4E
Interpretation Introduction
Interpretation:
The value of surface tension of liquid mercury,
Concept introduction:
Surface tension is the tension of a liquid surface that causes due to the attraction of liquid particles in the liquid surface by the liquid particle present in the bulk of the liquid. The surface tension tries to attain minimum surface area. The formula of surface tension is given by the expression shown below.

Coulombs Law describes the interaction between two charges and varies by the magnitude of these
charges and inversely with the distance between them.
For atoms, we'll label the charges as the
nuclear charge and electron charge.

As you go up in atomic number (Z), the number of protons in the nucleus increases, making the charge
on the nucleus increase, so that in general. qnuc
= Z ·(+1)
However if we think only of the electrons in the outermost shells (valence
electrons), they do not see the full strength of the nuclear charge because it
is partially shielded (or canceled out if you prefer) by the core electrons. So
we define something called effective charge.

Effective Charge = # of protons
Zeff = Z – core

In general, Zeff increases as you go across in the periodic table.

Given that a 10.0g sample of ice at 0.0 degrees celsius melts and then the resultant water proceeds to warm to 20.0 degrees celsius, there are two separate processes (dealing with the transfer of heat) that describe the occurence. What are those two processes? (Hint one involves the specific heat of water).
Determine the delta H of the following reactions:
CH4 (g) +2O2(g) → CO2 (g) +2H2O(l)
CH4 (g) +2O2(g) → CO2 (g) +2H2O(g)
What is the numerical difference between these two values?
What is the only physical difference between the two reactions?
What does the numerical difference represent, in terms of the physical difference between the two reactions?
A 4.00g sample of rocket fuel was combusted in a bomb calorimeter according to the following reaction:
2CH6N2(l)+ 5O2(g) → 2N2(g) +2CO2(g) + 6H2O(l)
The temperature of the surrounding calorimeter increased from 25.00C to 39.50 C and the heat capacity of the calorimeter was previously determined to be 7.794KJ/c. What is the…
