1

<li>Give the name and formula of each of the binary compounds formed from the following elements.</li>
</ol>

<p>(A) Li and N
(B) Na and Br
(C) K and S</p>

<li>Complete and balance the equations for the following reactions.</li>
</ol>

<p>(A) Cs (s) + H2O (l) ---->
(B) Na (s) + Cl2 (g) ----></p>

<p>104.</p>

<p>(A) Li2N, Lithium Nitride
(B) NaBr, Sodium Bromide
(C) K2S, Potassium Sulfide</p>

<p>Did I do them right? How do you do 110?</p>

3

<p>the 110a is a hyrdrogen displacement redox reaction</p>

<p>the 110b is a simple combination reaction you learn in middle school</p>

<p>

What is a hydrogen displacement redox reaction? What is the general form for this?</p>

<hr>

<p>Also, I need some hints for these problems.</p>

<p>7.92.c. What will be the formula of the neutral binary compounds that Uus (element 117) forms with sodium, magnesium, carbon, and oxgen?</p>

<p>7.92.d. What oxyanions would you expect Uus to form?</p>

<p>7.96.[A] Mg and K
a. Which atom has the more favorable (exothermic) electron affinity?</p>

<p>7.96.** F and Cl
a. Which atom has the more favorable (exothermic) electron affinity?</p>

<p>Actually the answer to 104a is Li3N, Lithium Nitride</p>
