Teniendo en cuenta la siguiente formula balanceada \[ \mathrm{N}_{2(g)}+3 \mathrm{H}_{2(g)} \rightarrow 2 \mathrm{NH}_{3(g)} \] Todas las moles son correctas, ExCEPTO: a. Hay 2 moles de \( \mathrm{NH}_{3} \) b. Hay 3 moles de \( \mathrm{H}_{2} \) c. Hay i mol de \( \mathrm{N}_{2} \) d. Hay z moles de \( \mathrm{H}_{2} \)

Simplify using the distributive property. \( 2(2 a+3)+8(a-4)=\square \)

An express delivery company charges \( \$ 3.25 \) per pound to mail a package. Georgia paid \( \$ 9.75 \) to mail a package. Write a multiplication equation that can be used to find the weight of the package in pounds. (Example 1 )

Perform the operation and simplify, if possible. \[ \frac{b^{2}-9 b+14}{b^{2}-10 b+16} \div \frac{b^{2}+2 b}{b^{2}-6 b-16} \]
