Answer:
a) The lewis dot structure is shown in the image attached to this answer
b) The formal charge on each of the atoms is zero
c) bromine has an oxidation state of +5 while fluorine has an oxidation state of -1
d) 90 degrees
e) Square Pyramidal
f) polar bonds
g) polar molecule
Explanation:
The molecule BrF5 has a formal charge of zero. It exhibits an sp3d2 hybridization state with a square pyramidal geometry. The bond angle in the molecule is 90 degrees. It is a molecule of the type AX5E. The oxidation state of bromine is +5 while that of fluorine is -1.
The Br-F bonds are polar. The overall molecule is polar due to asymmetric charge distribution concentrating on the central atom since the molecule is square pyramidal.
The time taken for the concentration of N2O to decrease to 32% of its initial concentration is calculated as follows
In(A1/A0)=-Kt
A1= final concentration = 32/100=0.32
A0= initial concentration =100/1000=1
K= constant= 0.76 per sec
time is therefore calculated as follows
In(0.32/1)= -0.76 t
-1.1394 =-0.76t divide both sid3es by -0.76
t is therefore= 1.5 s
The answer is B. Suspension. Suspension mixtures are composed of two or more materials mixed together wherein the solute particles are usually larger than those found in a solution or colloid. In cases of solid-fluid suspension mixtures, the solid solute particles tend to settle at the bottom of the mixture after some time.
Carbon monoxide (CO) is the name
Because the elements have not yet then been discovered.
Hope this helps.
