A 5.00 g sample of barium chloride hydrate was heated in a crucible. After the experiment, the mass of the solid weighed 4.26 g. Determine the number of moles of water that must be attached to BaCla$_{2}$. 1. Analyze the Problem Known: mass of hydrated compound = __ $\mathrm{g} \mathrm{BaCl}_{2} \cdot x \mathrm{H}_{2} \mathrm{O}$ mass of anhydrous compound = $\mathrm{g} \mathrm{BaCl}_{2}$ molar mass of $\mathrm{H}_{2} \mathrm{O}$ = ___ g/mol molar mass of $\mathrm{BaCl}_{2}$ = 208.23 g/mol Unknown: formula for hydrate name of hydrate 2. Solve for the Unknown Subtract the mass of the anhydrous compound from the hydrated compound. ________ Calculate the number of moles of $\mathrm{H}_{2} \mathrm{O}$ and anhydrous $\mathrm{BaCl}_{2}$ using the conversion factor that relates moles and mass based on the molar mass. $4.26 \ \mathrm{g} \ \mathrm{BaCl}_{2} \ \times$ = ____________ $0.74 \mathrm{g} \mathrm{H}_{2} \mathrm{O} \times$ = _____________ Determine the value of x. $$ x=\frac{\text { moles } \mathrm{H}_{2} \mathrm{O}}{\text { moles } \mathrm{BaCl}_{2}}= \qquad = \text{\_\_\_\_\_} $$ 3. Evaluate the Answer The ratio of $\mathrm{H}_{2} \mathrm{O}$ to $\mathrm{BaCl}_{2}$ is ________ so the formula for the hydrate is ________, and the name of the hydrate is ________.
CHEMISTRY
Sulfur dioxide is used to make sulfuric acid One method of producing it is by roasting mineral sulfides, for example, $\mathrm { FeS } _ { 2 } ( s ) + \mathrm { O } _ { 2 } ( g ) \longrightarrow \mathrm { SO } _ { 2 } ( g ) + \mathrm { Fe } _ { 2 } \mathrm { O } _ { 3 } ( s )$ [unbalanced] A production error leads to the sulfide being placed in a 950-L vessel with insufficient oxygen. The partial pressure of O2 is 0.64 atm, and the total pressure is initially 1.05 atm, with the balance N2. The reaction is run until 85% of the O2 is consumed, and the vessel is then cooled to its initial temperature. What is the total pressure and partial pressure of each gas in the vessel?
