The quantity of heat absorbed is 33.4 kJ.
Δ<em>H</em>_fus = 334 J·g⁻¹
<em>q = m</em>Δ<em>H</em>_fus = 100.0 g × 334 J·g⁻¹ = 3.34 × 10⁴ J = 33.4 kJ
Answer:
See explanation
Explanation:
Given that the formula of the compound is Fe2O3, if a coefficient of 2 is placed in front of the formula, that is, if we write 2Fe2O3 . Then;
The number of Fe atoms becomes 2 *2 = 4
The number of oxygen atoms becomes 2*3 = 6
That is why the total number of iron atoms were written down as 4.

Answer:
The bowling ball has more kinetic energy than the tennis ball
Explanation:
Using the formula 1/2 mass × acceleration we found that the tennis ball had a kinetic energy of 0.75 while the bowling ball had a kinetic energy of 10.5 hence the bowling ball has the ability to do more work
