Consider the thermochemical equation for the combustion of acetone (c3h6o), the main ingredient in nail polish remover. c3h6o (l) + 4 o2 (g) à 3 co2 (g) + 3 h2o (g) ∆horxn = -1790 kj if a bottle of nail polish remover contains 177 ml of acetone, how much heat is released by its complete combustion? the density of acetone is 0.788 g/ml.

-4.278 ×10³  kJ

Explanation:

The equation of the reaction is as follows:

The volume of acetone = 177mL

the density of acetone = 0.788 g/mL

Now;

To determine the mass of acetone ; we use the relation

mass = density × volume

mass = 177 mL × 0.788 g/mL

mass = 1.39 × 10² g

Since number of moles =

number of moles of acetone =

number of moles of acetone = 2.39 moles

Given that -1790 kJ of heat is released for one mole of combustion of acetone. To calculate the amount of heat released with 2.39 moles of acetone; we have:

= -4278.1 J

= -4.278 ×10³  kJ

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  

they are all solids.
