In the following reaction, eight moles of sodium hydroxide is broken down into four moles of sodium oxide and four moles of wate
maxonik [38]

Answer:

21.344%

Explanation:

For the given chemical reaction, 8 moles of the reactant should produce 4 moles of Na_{2}O. However, 195 g of Na_{2}O was produced instead. The molar mass of Na_{2}O is 61.9789 g/mol.

Thus, the moles of Na_{2}O produced = 195/61.9789 = 3.1462 moles

The percent error = [(Actual -Experiment)/Actual]*100%

The percent error =  [(4.00 - 3.1462)/4.00]*100% = (0.85376/4.00)*100% = 21.344%

What is the atom inventory for the following equation after it is properly balanced? ____K2S + ____CoCl2 Imported Asset ____KCl
Scilla [17]

Answer:

Reactants: K = 2, S = 1, Co = 1, Cl = 2; Products: K = 2, S = 1, Co = 1, Cl = 2

Explanation:

The reaction is a double replacement reaction so the anions (Cl⁻ and S²⁻) switch places.

<u>1</u> K₂S + <u>1</u> CoCl₂ ⇒ <u>2</u> KCl +  <u>1 </u>CoS (balanced chemical equation)

On the reactants and products side, K = 2, S = 1, Co = 1, and Cl = 2.

Hope that helps.
