For the chemical reaction: ${\mathrm{UF}}_6+2{\mathrm{H}}_2\mathrm{O}?{\mathrm{UO}}_2{\mathrm{F}}_2+4\mathrm{HF}$ write the conversion factor that would be needed to do each of the following one-step conversions. (a) Moles of ${\mathbf{UF}}_6$ to moles of $\mathbf{HF}$ (b) Moles of ${\mathrm{UO}}_2{\mathrm{F}}_2$ to moles of ${\mathrm{H}}_2\mathrm{O}$ (c) Moles of $\mathrm{HF}$ to moles of ${\mathrm{UO}}_2{\mathrm{F}}_2$ (d) Moles of ${\mathbf{H}}_2\mathbf{O}$ to moles of ${\mathbf{UF}}_6$ (a) $7.09\times 10^{23}{\mathrm{S}}_2\mathrm{O}$ molecules grams of sulfur (b) $7.00{\mathrm{S}}_4{\mathrm{N}}_4$ molecules grams of sulfur (c) $1.52$ moles ${\mathrm{SO}}_2$ molecules grams of sulfur (d) $4.47$ moles ${\mathrm{S}}_8$ molecules grams of sulfur Balance the following chemical equations. (Use the lowest possible coefficients. Omit states of matter.) a. ${\mathrm{C}}_6{\mathrm{H}}_8+{\mathrm{O}}_2?{\mathrm{CO}}_2+{\mathrm{H}}_2\mathrm{O}$ b. ${\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_3+{\mathrm{O}}_2?{\mathrm{CO}}_2+{\mathrm{H}}_2\mathrm{O}$ A mixture of hydrazine $\left({\mathrm{N}}_2{\mathrm{H}}_4\right)$ and hydrogen peroxide $\left({\mathrm{H}}_2{\mathrm{O}}_2\right)$ is used as a fuel for rocket engines. These two substances react as shown by the equation. ${\mathrm{N}}_2{\mathrm{H}}_4+2{\mathrm{H}}_2{\mathrm{O}}_2?{\mathrm{N}}_2+4{\mathrm{H}}_2\mathrm{O}$ What mass of ${\mathrm{N}}_2{\mathrm{H}}_4$, in grams, is needed to react completely with $40.3\mathrm{g}$ of ${\mathrm{H}}_2{\mathrm{O}}_2$ ? grams of ${\mathrm{N}}_2{\mathrm{H}}_4$ ${\mathrm{WO}}_3+3{\mathrm{H}}_2?3{\mathrm{H}}_2\mathrm{O}+\mathrm{W}$ How many grams of ${\mathrm{H}}_2$ are needed to produce $3.71\mathrm{g}$ of $\mathrm{W}$ ? (a) $4{\mathrm{NH}}_3+3{\mathrm{O}}_2?2{\mathrm{N}}_2+6{\mathrm{H}}_2\mathrm{O}$ (b) $({\mathrm{NH}}_4{\mathrm{CC}}_2{\mathrm{O}}_7?{\mathrm{N}}_2+4{\mathrm{H}}_2\mathrm{O}+{\mathrm{Cr}}_2{\mathrm{O}}_3$ (c) ${\mathrm{N}}_2{\mathrm{H}}_4+2{\mathrm{H}}_2{\mathrm{O}}_2?{\mathrm{N}}_2+4{\mathrm{H}}_2\mathrm{O}$ (d) $2{\mathrm{NH}}_3?{\mathrm{N}}_2+3{\mathrm{H}}_2$
