Maybe use flash cards for them to understand or look up periodic table on line and show them.
The answer would be a) body-centered cubic.
Answer:
A
Explanation:
a vector quantity must have a direction. without a direction the value is called a scalar quantity
ie: velocity is a vector because it is how fast an object moves in a certain direction. speed is a scalar because it is how fast an object moves regardless of direction
Ga₂O₃ + 2NaOH + 3H₂O = 2Na[Ga(OH)₄]
[Ga(OH)]⁻ + 3e⁻ = Ga + 4OH⁻
n(Ga)=It/(zF)
I=0.200 A
t=40.0 min=2400 s
z=3
F=96485.33 Kl/mol
n(Ga)=0.200*2400/(3*96485.33)=0.00166 =1.66*10⁻³ mol
