Neither F2 nor Br2 are polar because they are nonpolar. It is a good rule of thumb to know that any diatomic molecules like F2 or Br2 are always going to be nonpolar. Another way to determine this is to use the acronym SNAP ( symmetrical=nonpolar, asymmetrical=polar). Since both F2 and Br2 are symmetrical molecules, they must be nonpolar.
I hope this helps.
Answer:
35.47+10.1 is 45.57, I hope that helped nc I'm new to this app and yea.
Answer:
pH before addition of KOH = 4.03
pH after addition of 25 ml KOH = 7.40
pH after addition of 30 ml KOH = 7.57
pH after addition of 40 ml KOH = 8.00
pH after addition of 50 ml KOH = 10.22
pH after addition 0f 60 ml KOH = 12.3
Explanation:
pH of each case in the titration given below
(6) After addition of 60 ml KOH
Since addition of 10 ml extra KOH is added after netralisation point.
Concentration of solution after addition 60 ml KOH is calculated by
M₁V₁ = M₂V₂
or, 0.23 x 10 = (50 + 60)ml x M₂
or M₂ = 0.03 Molar
so, concentration of KOH = 0.03 molar
[OH⁻] = 0.03 molar
pOH = 0.657
pH = 14 - 0.657 = 13.34
Answer:
Percentage yield is 96.15%
Explanation:
Theoretical yield = 13.0g
Actual yield = 12.5g
Percentage yield = ?
Equation of reaction
2Na + Cl₂ → 2NaCl
Percentage yield = (actual yield / theoretical yield) * 100
Percentage yield = (12.5 / 13.0) * 100
Percentage yield = 0.9615 * 100
Percentage yield = 96.15%
Percentage yield of NaCl is 96.15%
I personally think b is the correct answer.
A-children don't think about what adults should do
B-limits give children skills to solve problems in life as they grow
C-its good to let a child know whats right and wrong
D-Limits wouldn't give kids insecurity
Please tell me if i'm right or wrong!:)
