Answer:
27J/Kmol
Explanation:
Heat = number of moles times the Moeller heat capacity chimes the change in temperature.
^ Q = nC△T
^ C = Q/ n△T = +53J / (1mol) (299.5K - 297.5K)
^ = 26.5 (rounded to 27)
Answer:
Al₄O₅
Explanation:
The key at the bottom tells us the blue spheres are oxygen atoms and the red spheres are aluminum atoms. By counting, there are 4 aluminum atoms and 5 oxygen atoms. Therefore, the formula is Al₄O₅.
