Answer: 1.11 g/mL
Explanation:
Density = mass/vol
mass 123.0194-120.3621g = 2.6574
vol 6.518-4.126 ml = 2.392
Answer:
Chlorine
Explanation:
chlorine is the element that shows similar chemical properties as bromine because this element is in the same group in the periodic table show similar properties they belong to 17th group.
Answer:
Water has the greatest ΔEN
ΔEN H₂O → 3.4 - 2.1 = 1.3 Option D.
Explanation:
We should find the Electronegativity data in the Periodic table for all the elements:
C : 2.6
O: 3.4
H: 2.1
S: 2.6
N: 3.0
a. ΔEN CO₂ → 3.4 - 2.6 = 0.4
b. ΔEN H₂S → 2.6 - 2.1 = 0.5
c. ΔEN NH₃ → 3 - 2.1= 0.9
d. ΔEN H₂O → 3.4 - 2.1 = 1.3
