The decomposition of CCl4 is as follows:
CCl4 (g) ---> C(s) + 2Cl2 (g) Kp = 0.76
where Kp = (PCl2)^2 / (P_CCl4)
P_C is zero since carbon is in solid form.
Express P_CCl4 in terms of P_Cl2
0.76 = (P_Cl2)^2 / (P_CCl4)
0.76P_CCl4 = (P_Cl2)^2
Ptotal = P_Cl2 = 1.9 atm
Solve for P_CCl4
P_CCl4 = 4.75 atm<span />

Answer:
The <em>C)</em> statement is true.
Explanation:
Let's call <em>
</em> the average for the first class and <em>
</em>the average for the second class. The overall average <em>x</em> is then:

Since the average is given by <em>
</em>. We can now calculate <em>x</em> assuming the maximun and minimun values of <em>
</em>, 2400 (which is 100 times 24) and 0 respectivly. That gives:

for it's maximun value and

for it's minimun value. So we get that <em>x</em> is between 36% and 93%.
Answer:
There is a couple different ways to determine if a bond is ionic or covalent. By definition, an ionic bond is between a metal and a nonmetal, and a covalent bond is between 2 nonmetals. So you usually just look at the periodic table and determine whether your compound is made of a metal/nonmetal or is just 2 nonmetals.

Answer:
Acid neutralizes base to form salt and water while white colour neutralizes black colour to form grey colour.
Explanation:
Neutralization is simply the process whereby an acid and a base are mixed to produce salt and water. Now, this reaction also involves the mixing of the hydrogen ions of the acid and hydroxide ions of the base to form the salt and water. It is similar to mixing 2 paints to form another colour in that in the neutralization reaction 2 compounds are mixed to neutralize each other to form another compound while in mixing black and white to form grey the two colors are mixed together and thereby neutralized to form another colour which is grey.
