Answer:
-943J or 943J released
Explanation:
m=2.4 mol x 207.g/ mol=497.3g
c=.129 J/gC
T= T f-Ti=(22.5-37.2)=-14.7C
Q=?
Q=(49.3g)(.129 J/g C) (-14.7 C)
= -943 J or 943 J released
I’m pretty sure it’s D because energy measures the kinetic, thermal, electrical, chemical, nuclear and other forms.
Answer:
Using the graph, we can see that after 4.5 minutes, the bus traveled 4500 meters. Find 4.5 on the x axis, and then see what y value it corresponds to.
Let me know if this helps!
48g LiOH/ 23.95g = 2.0041 moles
Molarity= Mole of solute / liter of solution
Molarity= 2.0041 M
Molarity = 2.0 M
