Number of moles ( n ) = ?
Volume ( V ) = 0.25 L
Molarity of solution ( M ) = 2.00 M
n = M x V
n = 2.00 x 0.25
n = 0.5 moles of Ba(NO₃)₂
hope this helps!
Answer:
An impurity is something that ruins the uncontaminated nature of something. If someone accuses you of impurity, they think you or your nature has been spoiled in some way by sin. When water is pure, the only thing in that water is water.
If the reaction is
X + Y → Products
Then the rate is
R = k[X]ᵃ [Y]ᵇ
Where,
R = the rate of the reaction (mol L⁻¹ s⁻¹)
k = rate constant
[X] and [Y] = concentrations of the reactants (mol L⁻¹)
a = order of the reaction with respect to X
b = order of the reaction with respect to Y
overall reaction order, n = a + b
according to the given rate expression,
rate = [a][b]³
order of the reaction with respect to 'a' is 1
order of the reaction with respect to 'b' is 3
Overall reaction order = 1 + 3
= 4
It means it is an ion. It has lost two protons making it a positive ion.
