Question

question 1 (1 point)
use the following information to answer the next question.
the thermochemical equation for the formation of methyl alcohol indicates that 239 kj of energy is released and 32 g of methyl alcohol is formed.
the formation of 64 g of methyl alcohol will release energy equivalent to
239 kj
478 kj
1529.6 kj
956 kj
119.5 kj

Explanation:

Step1: Determine the ratio of masses

We know that 32 g of methyl alcohol releases 239 kJ. We need to find the energy released for 64 g. First, find the ratio of 64 g to 32 g.
Ratio = $\frac{64\ g}{32\ g}$ = 2

Step2: Calculate the energy released

Since the amount of energy released is proportional to the mass of methyl alcohol formed, we multiply the energy released for 32 g by the ratio.
Energy released = 239 kJ × 2 = 478 kJ

Answer:

478 kJ (corresponding to the option "478 kJ")
