What is the percent yield for carbon dioxide if 10.0 grams of carbon
ivolga24 [154]

The percent yield : 81.5%

<h3>Further explanation</h3>

Percent yield is the compare of the amount of product obtained from a reaction with the amount you calculated

General formula:

Percent yield = (Actual yield / theoretical yield )x 100%

An actual yield is the amount of product actually produced by the reaction. A theoretical yield is the amount of product that you calculate from the reaction equation according to the product and reactant coefficients

Reaction

2CO+O₂⇒2CO₂

mol CO(MW=28,01 g/mol)

\tt \dfrac{10}{28.01}=0.357

mass CO₂ (theoretical)(MW=44,01 g/mol)

\tt 0.357\times 44.01=15.712~g

the percent yield :

\tt \dfrac{12.81}{15.712}\times 100\%=81.5\%

g How many grams of beryllium are needed to produce "11.5" g of hydrogen gas?Be(s) + 2H 2 O(l) → Be(OH) 2 (aq) + H 2 (g)
slega [8]

Answer:

m_{Be}=51.3gBe

Explanation:

Hello,

In this case, with the given chemical reaction:

Be(s) + 2H_2 O(l) \rightarrow Be(OH)_ 2 (aq) + H _2 (g)

We can notice a 1:1 mole ratio between hydrogen gas and beryllium metal, therefore, beryllium requirement is computed as shown below:

m_{Be}=11.5gH_2*\frac{1molH_2}{2.02gH_2} *\frac{1molBe}{1molH_2} *\frac{9.01gBe}{1molBe}\\ \\m_{Be}=51.3gBe

Regards.
