Answer:
a. the electrons shared between the oxygen and hydrogen atoms spend more time around the oxygen atom nucleus than around the hydrogen atom nucleus.
Explanation:
Water molecule is a polar molecule , and hence , the atom can attain the respective partial positive and negative charge on them .
The difference in the electronegativity gives rise to the partial positive and negative charge .
Since , oxygen atom is more electronegative in comparison to hydrogen atom , and hence , slightly pulls the electrons towards itself , and attains partial negative charge , and correspondingly , the hydrogen atom attains partial positive charge .
Hence , from the question ,
The correct option is a.
This is false, a compound does not have to contain both cations and anions if ions are present.
Answer:
%age Yield = 20.12 %
Solution:
The Balance Chemical Reaction is as follow,
Cl₂ + 3 F₂ → 2 ClF₃
According to Equation ,
114 g (3 mole) F₂ produces = 184.88 g (2 moles) of ClF₃
So,
19.2 g of F₂ will produce = X g of ClF₃
Solving for X,
X = (19.2 g × 184.88 g) ÷ 114 g
X = 31.13 g of ClF₃ (Theoretical Yield)
As we know,
%age Yield = (Actual Yield ÷ Theoretical Yield) × 100
%age Yield = (6.3 g ÷ 31.3 g) × 100
%age Yield = 20.12 %
