When 1.0 g of gasoline burns, it released 11 kcal of heat. The density of gasoline is 0.74 g/mL. How many Joules of heat is released when 1.5 gallons of gasoline burns?

Explanation:

Hello!

In this case, since we first know the heat and mass of the first experiment, we are able to compute enthalpy of vaporization of gasoline as shown below:

Next, we need to the compute the grams in 1.5 gallons of gasoline via its density with the proper units:

Therefore, the new joules are computed via:

Best regards!

the answer is true. hope it .

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
