We subtract the enthalpies of the reactants from that of the products:

Since this is < 0, this is an exothermic reaction.
Change occurs in the density of the gummy bear to change if we soaked it in isopropanol.
<h3>Effects on density by soaking isopropanol</h3>
We expect the density of the gummy bear to change if we soaked it in isopropanol because the gummy bear absorb the liquid which increase its density due to increasing weight of the gummy bear.
If a substance gains weight then its density also increases and we know that when the gummy bear was soaked in the isopropanol then its weight increases so its density is also changes so we can conclude that change occurs in the density of the gummy bear to change if we soaked it in isopropanol.

Answer and Explanation:
The options aren't listed in your question, but here are some units that are regularly and normally used (in the classroom and in the outside world):
(The SI unit of distance and displacement is the meter. The SI unit of time is the second.)
<u>Meters per Second (m/s)</u>
kilometers per hour (km/hr)
kilometers per second (km/sec)
To find the average speed, you do distance divided by time.
To find the average velocity, you do the final position minus the initial position, divided by the final time minus the initial time.
