How many grams of carbon dioxide are produced by complete combustion of 5 grams of c5h10
Lemur [1.5K]

Answer:

15.4 g

Explanation:

The reaction that takes place is:

  • 2C₅H₁₀ + 15O₂ → 10CO₂ + 10H₂O

First we <u>convert 5 grams of C₅H₁₀ into moles</u>, using its <em>molar mass</em>:

  • 5 g ÷ 70 g/mol = 0.07 mol C₅H₁₀

Then we <u>convert C₅H₁₀ moles into CO₂ moles</u>, using the <em>stoichiometric coefficients</em> of the reaction:

  • 0.07 mol C₅H₁₀ * \frac{10molCO_2}{2molC_5H_{10}} = 0.35 mol CO₂

Finally we <u>convert 0.35 moles of CO₂ into grams</u>:

  • 0.35 mol CO₂ * 44 g/mol = 15.4 g

carol accidentally dropped a container of salt and sodium chloride, into a container of a dark grey metal. carol is pretty sure
o-na [289]

Explanation:

The best way to separate the mixture is by using a bar magnet. We explore the magnetic property of the iron fillings in the mixture to separate it out.

  • The mixture is spread out thinly on a flat surface.
  • A bar magnet is hovered above the spread of the mixture
  • The magnet attracts the iron fillings to itself
  • This will leave the salt behind in the mixture.
