Answer:
2.04 x 10⁻⁶ moles H₂O
Explanation:
To find the moles H₂O, you need to multiply the given value by Avogadro's Number. This number is a ratio between molecules and moles, thus granting you the way to convert between both units. It is important to arrange the ratio in a way that allows for the cancellation of units. The final answer should have 3 sig figs to match the sig figs of the given value (1.23 x 10¹⁸ molecules).
Avogadro's Number:
6.022 x 10²³ molecules = 1 mole
1.23 x 10¹⁸ molecules H₂O 1 mole
--------------------------------------- x ------------------------------------- =
6.022 x 10²³ molecules
= 2.04 x 10⁻⁶ moles H₂O
M2= 0.35M
Formula: M1 • V1 = M2 • V2
1) 25.0mL • .500M = 35.5mL • (x)
2) 12.5 = 35.5 • (x)
3) 12.5/35.5 = x
4) 0.35211 = x = M2
Hope this helps!
Answer: C REDUCTION
Explanation:
Guessed after knowing oxidation isn't the answer. Got right
Not sure if this is right but this is what I think
Thermal energy added: Particles move faster, Kinetic energy increases, Temperature increases
Thermal Energy removed: Particles move slower, Kinetic energy decreases, Temperature decreases
