Answer
Accordingly the order of electronegativity of the given elements would be: Fluorine > Chlorine > Bromine > Iodine. ( Fluorine has the highest electronegativity.)
Answer:
protons=1
electrons=1
neutrons=0
Explanation:
protons and electrons are equal in their natural state when it goes under any reaction the protons of that element remain the same but the number of the element changes.
Answer:
Polar covalent.
Explanation:
The covalent bonds are therefore polar, and the oxygen atoms have a slight negative charge (from the presence extra electron share), while the hydrogens are slightly positive (from the extra un-neutralized protons). Opposite charges attract one another.
Answer:
Theoretical yield of sodium chloride = 14.04 g
Explanation:
Given data:
Mass of sodium bromide = 25 g
Theoretical yield of sodium chloride = ?
Solution:
Chemical equation:
NaBr + KCl → NaCl + KBr
Number of moles sodium bromide:
Number of moles = Mass /molar mass
Number of moles = 25.0 g / 102.9 g/mol
Number of moles = 0.24 mol
Now we will compare the moles of NaCl with NaBr .
NaBr : NaCl
1 : 1
0.24 : 0.24
Theoretical yield of sodium chloride:
Mass = moles × molar mass
Mass = 0.24 mol × 58.5 g/mol
Mass = 14.04 g
