Answer: a) 0.06 M
b) 3.13 grams.
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
Moles of
The balanced reaction for dissociation will be:
Thus for 4 moles of , there is 1 mole of
Thus moles of
Molarity of
Thus the molarity of the solution = 0.06 M
b) Mass of =
Thus mass of Wenzhou use is 3.13 grams.
Answer:
Zinc Chloride + Difluorine -----> Zinc Fluoride + Dichlorine
Explanation:
ZnCl2 + F2 → ZnF2 + Cl2
Liquid water being put into a freezer is a process of liquid to solid.
Liquid water in a kettle turning into steam is a process of liquid to gas.
Answer: slower and closer together,
Explanation:
Kinetic energy=Ek
Ek=(1/2)mv²
Ek=480 J
v=8 m/s
mass=?
Ek=(1/2)mv²
480 J=(1/2)m(8 m/s)²
480 J=(32 m²/s²) m
m=(480 J)/(32 m²/s²)=15 kg
answer: the mass of the object is 15 kilograms.
