2C4H10+13O2--&gt;8CO2+10H2O Using the predicted and balanced equation, How many Liters of CO2 can be produced from 150 grams of
Anna11 [10]

Answer:  233 L of CO_2 will be produced from 150 grams of  C_4H_{10}

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}  \text{Moles of} C_4H_{10}=\frac{150g}{58g/mol}=2.59moles

The balanced chemical equation is:

2C_4H_{10}+13O_2(g)\rightarrow 8CO_2+10H_2O  

According to stoichiometry :

2 moles of C_4H_{10} produce =  8 moles of CO_2

Thus 2.59 moles of C_4H_{10} will produce=\frac{8}{2}\times 2.59=10.4moles  of CO_2  

Volume of CO_2=moles\times {\text {Molar volume}}=10.4moles\times 22.4mol/L=233L

Thus 233 L of CO_2 will be produced from 150 grams of  C_4H_{10}

Analyisis Of Compound (%)<br> C=72.15 H=7.08 N=4.68 O=16.03<br> What is it?
klemol [59]

Answer:

Explanation:

Ratio of C : H : N : O  in grams

=  72.15 : 7.08 : 4.68 : 16.03 in grams

Ratio of C : H : N : O in moles

72.15/12 : 7.08/1 : 4.68/14 : 16.03/16 in moles  

6.01 : 7.08 : .334 : 1.00

6.01/ .334  : 7.08/.334 : .334/.334 : 1.00/.334   in moles

18 : 21.19 : 1 : 3

18 : 21 : 1 : 3
