Answer:

A. oxygen

B. chlorine

2. iodine

(a) because aluminium is a soft malleable metal. it can be made to in sheets to form thin wrapping sheets. also, it does not react with food items.

(b) because metals are good conductors of heat and electricity. the immersion rod needs electric supply to get heated and to heat liquids.

(c) they're kept in kerosene to keep them from coming in contact with oxygen and moisture as they react to form their hydroxides.

4. Magnesium is a metal. Metals react with oxygen to form metallic oxides. So Magnesium oxides are basic in nature. But nonmetals react with oxygen to form nonmetallic oxides. These oxides differ from metallic oxides because they are acidic in nature. Nonmetallic oxides react with water to form acids. Therefore, Sulphur dioxide is acidic in nature. Magnesium oxide is basic in nature.

5. Copper forms a green deposit on its surface when exposed to air which is usually a mixture of copper carbonate and copper hydroxide. It's acidic in nature.

The molecule with the largest dipole moment (a) co2 (b) h2o (c) ch4 (d) c2h4 (e) ph3

storchak [24]

The molecule with the largest dipole moment will be $CH_{4}$ .

A dipole moment would be a unit used to describe how far apart two electrical charges are from one another. Dipole moments represent a type of vector. The direction could be from negative charge to positive charge, while the magnitude has been equal to the charge times the distance between most of the charges.

The polar bonds, of $CO_{2}$ as well as $H_{2} O$ have chemical configurations where the polarity cancels, leaving no net dipole. Regardless of the molecule's shape, $CH_{4}$ lacks a net dipole due to its non-polar links.
