2C4H10+13O2-->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}

Metals such as iron, lead, copper, and zinc have relatively ___ specific heats. This means it takes ___ energy to chan thejr tem
ivann1987 [24]

B. Low; very little

Explanation:

Metals such as iron, lead, copper and zinc have low specific heats. This means that it takes very little energy to change their temperature.

Specific heat is the heat required to raise the temperature of 1g of substance by 1°C.

Metals have good thermal conductivity and generally have low specific heat. This implies that their temperature can easily be raised when heated.

Some substances like water have very high specific heat. This suggests that they require more heat to raise their temperature.
