The mass numbers for two isotopes are unequal because they have different numbers of NEUTRONS.
Answer:
The air particles are sped up and they are more spaced apart.
Explanation:
This is because when things are heated up the particles speed up and flow more freely causing them to be space apart.
Answer:
pH = 12.544
Explanation:
0.0350M 0.0350M 0.0350M.........equilibrium
∴ pOH = - log [OH-]
∴ pH + pOH = 14
⇒ [OH-] = 0.0350 M
⇒ pOH = - Log (0.0350)
⇒ pOH = 1.456
⇒ pH = 14 - 1.456
⇒ pH = 12.544
Answer:
Explanation:
The molality of a solution, m is defined as the number of moles of the solute that is dissolved in 1 kg of solvent.
m = number of moles/kilogram of solvent
