[Answered] The reaction below is at dynamic equilibrium. [tex]$N_2(g)+3 H_2(g) \longleftrightarrow 2 NH_3(g)$[/tex] Which statement is true for the equilibrium system? A. The concentration of [tex]$NH _3$[/tex] is greater than the concentration of [tex]$N _2$[/tex]. B. The rate of the forward reaction equals the rate of the reverse reaction. C. The rate of the forward reaction is greater than the rate of the reverse reaction.

[Answered] Evaluate the expression $2 x-(4 y-3)+5 x z$, when $x=-3, y=2$, and $z=-1$. A. 45 B. 16 C. 4 D. -10

[Answered] Given: [tex]$\begin{array}{c} A B=12 \ A C=6 \end{array}$[/tex] Prove: C is the midpoint of [tex]$\overline{ AB }$[/tex]. Proof: We are given that [tex]$AB =12$[/tex] and [tex]$AC =6$[/tex]. Applying the segment addition property, we get [tex]$A C+C B=A B$[/tex]. Applying the substitution property, we get [tex]$6+ CB =12$[/tex]. The subtraction property can be used to find [tex]$CB =6$[/tex]. The symmetric property shows that [tex]$6=A C$[/tex]. Since [tex]$C B$[/tex] [tex]$=6$[/tex] and [tex]$6= AC , AC = CB$[/tex] by the property. So, [tex]$\overline{ AC } \cong \overline{ CB }$[/tex] by the definition of congruent segments. Finally, C is the midpoint of [tex]$\overline{ AB }$[/tex] because it divides [tex]$\overline{ AB }$[/tex] into two congruent segments.

[Answered] There is no guarantee that information will be accurate, even when you carefully select knowledgeable sources. True or False?

[Answered] What is the value of [tex]$x$[/tex] in the equation below? [tex]$1+2 e^{x+1}=9$[/tex] A. [tex]$x=\log 4-1$[/tex] B. [tex]$x=\log 4$[/tex] C. [tex]$x=\ln 4-1$[/tex] D. [tex]$x=\ln 4$[/tex]

[Answered] In Miranda v. Arizona (1966), why did Ernesto Miranda say his Fifth Amendment rights were violated? A. He had been stopped and searched without a judge issuing a proper warrant. B. He had been tried for serious crimes without a grand jury issuing an indictment. C. He had confessed to crimes without being reminded of his right to avoid self-incrimination. D. He had been jailed without being informed of the charges against him.

[Answered] On a number line, the directed line segment from Q to S has endpoints Q at -14 and S at 2. Point R partitions the directed line segment from [tex]$Q$[/tex] to [tex]$S$[/tex] in a 3:5 ratio. Which expression correctly uses the formula [tex]$\left(\frac{m}{m+n}\right)\left(x_2-x_1\right)+x_1$[/tex] to find the location of point [tex]$R$[/tex]? A. [tex]$\left(\frac{3}{3+5}\right)(2-(-14))+(-14)$[/tex] B. [tex]$\left(\frac{3}{3+5}\right)(-14-2)+2$[/tex] C. [tex]$\left(\frac{3}{3+5}\right)(2-14)+14$[/tex] D. [tex]$\left(\frac{3}{3+5}\right)(-14-2)-2$[/tex]
