Answer:
O-H
N-H
Br-H
C-H
Si-H
Explanation:
Oxygen having electronegativity of 3.44 eV while hydrogen having electronegativity 22.2 eV. So oxygen will attract electrons more strongly than hydrogen because of higher electronegativity and produce a dipole. the electronegativity difference between them is 1.24eV which means it is polar compounds because if the electronegativity difference between bonded molecules are 0.4-2.0 eV indicated the compounds is polar. And same rule apply for rest of the options.
Answer:
the molecular formula of Ozone is O_3.
A sample of material is found to have a mass if 33.03 grams (g), and a volume of 2.624 ml, hence the metal is Silver.
∴ Silver = 12.59 g/mL
The elements of group 11 (Cu, Ag, and Au) are called coinage metals because they are used in minting coins. These metals are malleable. They have the ability to get converted into sheets.
The coinage metal comprise, at a minimum, those metallic chemical elements which have historically been used as components in alloys used to mint coins.
The coinage metals have the highest electrical and thermal conductivities of all the metals, and they are also the most ductile and malleable.

I think the answer is B or the 2nd one, hope this helped c:
The answer is the third one which is C
