Melting is the phase change when solid becomes liquid
1. mol = 77.56/100 = 0.7756 mol
2. mol = 2.55 × 10^24/6.02 × 10^23 = 4.236 mol mass = 4.236 × 74.5 = 315.582 g
3. mass = 0.0931 × 208.3 = 19.393 g
4. mol = 1.55 × 10^22/6.02 × 10^23 = 0.0257 mol
5. molecules = 0.664 × 6.02 × 10^23 = 3.997 × 10^23 molecules
6. mol = 86/242 = 0.355 mol
7. mol = 7.88 × 10^23/6.02 × 10^23 = 1.309 mol mass = 1.309 × 44 = 57.596 g
8. mass = 7.56 × 62 = 468.72 g
9. mol = 7.56/84 = 0.09 mol
10. mol = 8.55 × 10^21/6.02 × 10^23 = 0.014 mol mass = 0.014 × 58.5 = 0.819 g

Based on the trend from the graph, the reaction time would have been 32.5 seconds.
<h3>What is the trend in the graph?</h3>
A trend is a general pattern which an observation follows based on previous observations and occurrences.
The reaction time is the time it take for a chemical reaction to occur.
Reaction time is also a measure of reaction rate. The shorter the reaction time, the faster the reaction rate and vice versa.
Based on the trend from the graph, the reaction time would have been 32.5 seconds.
In conclusion, reaction time is a measure of reaction rate.

Your weight is a measure of ibs/pounds
Answer:
The Sun radiates huge amounts of energy. Only a small portion of that energy hits the Earth, but it is enough to light our days, heat our air and land, and create weather systems over the oceans. Most of the energy you will learn about comes from the Sun. The Earth also gives off energy.
