lead(IV) chloride
The conversion factor from pounds-mass (lbm) to pounds-mole (lbmol) is the molecular weight of the substance in pounds per mole.
The conversion factor from grams per mole (g/mol) to pounds mass per pound mole (lbm/lbmol) is 0.00220462.
The conversion factor from grams per mole (g/mol) to daltons is 1 g/mol 1 dalton.
The formula for lead(IV) chloride is PbCl4. It is composed of one lead (Pb) atom and four chloride (Cl) ions.
The chemical formula for lead(IV) chloride is PbCl4.
Use dimensional analysis to solve this problem. First calculate the molecular mass of CO2. This is found by (use a periodic table) adding 12.011g of C to (15.999g x2) grams of Oxygen. Once you do that, you find out that 44.009g are in 1 mole of CO2. Now, simply by looking at the equation of CO2, we can tell that 2 moles of oxygen atoms are in 1 mole of Co2 (look at the subscript for Oxygen). Now, your dimensional analysis should look like this: 254g CO2 x 1 mole CO2/44.009g CO2 x 2 mole Oxygen/1 mole CO2 The answer is 11.5 moles of Oxygen in 254g of CO2.

pbcl4
The correct name for the compound PbCl4 is lead(IV) chloride.
PbCl2 is more stable than PbCl4 primarily due to the oxidation states of lead. In PbCl2, lead is in the +2 oxidation state, which is a more stable oxidation state for lead compared to the +4 state found in PbCl4. The +4 oxidation state is less stable because it leads to increased electron-electron repulsion and makes PbCl4 more susceptible to reduction. Additionally, PbCl2 has a stronger ionic character compared to PbCl4, contributing to its greater stability.
Coefficients
Three common conversion factors used in mole conversions are: Avogadro's Number: 1 mole = (6.022 \times 10^{23}) particles (atoms, molecules, etc.). Molar Mass: The mass of one mole of a substance in grams, expressed in g/mol (e.g., for water, it's approximately 18 g/mol). Volume at STP: For gases, 1 mole occupies approximately 22.4 liters at standard temperature and pressure (STP).
