Answer:
True.
Explanation:
Dissolution changes the properties of molecules or atom.
Atomic number is Z. Z=number of protons, so Z=11
Answer:
0.02 m
Explanation:
∆U = q + w
w = ∆U - q = (1380 - 2040) J = -660 J
w = -p∆V = -pA∆h
∆h = -w/(pA)
p = 1 bar × (100000 Pa/1 bar) = 100000 Pa
∆h = -(-660 J)/(100000 Pa×0.33 m²) = 0.02 m
Answer:
Explanation:
Well you didn’t send a picture of the question but h2O is water so. If the questions answer has a option of water then pick that one
