Answer: The anwer is ionic, yes
Fore the Ions in Polar Solvents Quick Check its
1. B) Water dissolves more substances than any other solvent
2. D) electron shared between atoms
3. B) slightly negative oxygen pole, slightly positive hydrogen poles
4. B) The electron transfer in ionic compounds results in ions that are attracted to water’s poles.
5. C) ionic, yes
Please note that Im in Honors Chemistry and our qestions may not be exactly the same
<span>In beta minus (β−) decay, a neutron is converted to a proton and the process creates an electron and an electron antineutrino; while in beta plus (β+) decay, a proton is converted to a neutron and the process creates a positron and an electron neutrino. β+ decayis also known as positron emission.</span>
Answer:
S AgBr = 2.82 E-3 mol/L
Explanation:
- AgBr ↔ Ag+ + Br- .....(1)
∴ Ksp = [ Ag+ ] * [ Br- ] = 5.0 E-13
- Ag+ + 2NH3 ↔ [ Ag(NH3)2 ]+ ..........(2)
∴ Kf = 1.6 E7 = α[Ag(NH3)2]+ / ( αAg+ )*( αNH3 )²
∴ <em>C </em> NH3(sln) = 1.00 M
from (1) + (2):
- AgBr(s) + 2NH3(aq) ↔ Ag(NH3)2+(aq) + Br-(aq)
1 M 0 0
1 - 2x x x
∴ K = Ksp*Kf = ( 5.0 E-13 )*( 1.6 E7 ) = 8.0 E-6
⇒ K = ( [ Br- ] * [ Ag(NH3)2+] ) / [ NH3 ]² = 8.0 E-6
⇒ K = (( x )*( x )) / ( 1 - 2x ) = 8.0 E-6
⇒ x² = 8.0 E-6*( 1- 2x )
⇒ x² + 1.6 E-5x - 8.0 E-6 = 0
⇒ x = 2.82 E-3 M
⇒ [ Br- ] = [ AgBr ] = 2.82 E-3 M
It’s 3670 because 66plus 86 is 3670 I need point so I am doing this
