After 3 half lives it will be (1/2)^3 or 1/8 of original
so
1/8 times 10^8=1.25 x 10⁶ atoms left
Answer:
This charge transfer led to the formation of pentacoordinated square pyramidal MX·(YZ3) adducts with M·Y dative bond. Binding energies were -44.7 and -75.2 kcal/mol for interaction of GaF3 as the strongest acid with PtNCN
To satisfy the octet rule, there has to be eight electrons in phosphorus's outermost shell. Phosphorus has five electrons in its valence shell, fluorine has seven. This means that phosphorus would have to bond to three fluorine atoms in order to have eight electrons in its valence shell without breaking the octet rule in any one of the fluorine atoms.
Answer:
22.73s
Explanation:
The reaction is a second order reaction, we know this by observing the unit of the slope.
rate constant = k = 0.056 M-1s-1
the initial concentration of BrO- [A]o = 0.80 M
time = ?
Final concentration [A]t= one-half of 0.80 M = 0.40M
1 / [A]t = kt + 1 / [A]o
1 / 0.40 = 0.056 * t + 1 / 0.80
t = (2.5 - 1.25) / 0.056
t = 22.73s
