The IE of H is 1.31 MJ/mole. If all three electrons in Li were in the 1st shell at a distance equal to that of H, which of the following values would be the better estimate of the first ionization energy of Lithium: 3.6 MJ/mole or 0.6 MJ/mole? Why?
As is often the case with questions such as these, I often find that the best approach begins with a definition. Here, let's consider a typical definition of first ionisation...

Since $C Cl_4$ is made up of one carbon and four chlorine atoms, how many total valence electrons does $C Cl_4$ have?
The carbon atom, $Z=6$, has $4$ , all of which are conceived to participate in the $4$ $C-Cl$ bonds. There are $7$ valence electrons on each chlorine atom; one of...

The Cl-Cl bond energy is 243 kJ/mol. Therefore the formation of a single bond between chlorine atoms ?
A) should require the absorption of 243 kJ per mole of $Cl_2$ formed.
B) should result in the release of 243 kJ per mole of $Cl_2$ formed.
The bond energy, or bond , expresses the energy needed to break a chemical bond, that's why it will always be listed as a positive value. In your case, 243...

How do you draw $CS_2$ in Lewis structure?
For $CO_2$, we gots $:stackrel(ddot)O=C=stackrel(ddot)O:$; carbon is $sp-"hybridized"$, and oxygen is $sp^2-"hybridized"$. The carbon-sulfur bond is approx. $1.55xx10^-10*m$; for $C-S$ in $RSH$ compare values of approx. $1.75xx10^-10*m$ for a $C-S$...

How do you balance the equation for this reaction: $C(s) +SO_2(g) -> CS_2(l) + CO_2(g)$?
$C(s) + SO_2 (g) → CS_2 (l) + CO_2 (g)$ We have: LHS C= 1 S= 1 O=2 RHS C=2 S=2 O=2 We balance the...

What is the mole ratio of $Cl_2$ to $Br_2$ in the reaction $Cl_2+2NaBr->2NaCl+Br_2$?
There is no coefficient in front of the $"Cl"_2"$ or the $"Br"_2"$, which is understood to be 1 mole.

For the reaction,$2x$+$3y$+$4z$$ rarr$$ 5w$
Initially if 1 mole of $x$,3 mole of $y$ and 4 mole of $z$ is taken and 1.25 mole of $w$ is obtained then what is the % yield of this reaction?
This is a limiting reactant problem. We know that we will need a balanced equation and moles of each reactant. 1. Gather all the information in one place with...

The attached plot shows the
ratio of PV to RT for 1.0 mole of nitrogen
gas as a function of pressure at T=1000K.
Explain why the ratio should be 1.0 for
an ideal gas, and why nitrogen does not
behave ideally at high pressures?
The ideal gas law is an idealization. What does this mean? It means that we idealize the behaviour of real gases. We assume that gases are mostly empty space, that...

Which sample has the most number of atoms?
$A.$ $"1 mole of oxygen atoms;"$
$B.$ $"1 mole of oxygen molecules;"$
$C.$ $"1 mole of ozone molecules;"$
$D.$ $"Each sample contains the same number of atoms."$
Mass is a measure of the number of particles. Here you have $O$ atoms, and dioxygen, $O_2$, and ozone molecules, $O_3$ but each have the same mass by specification. There...
