Answer:
0.25 mm> 0.50 mm > 0.75 mm> 1mm> 1.25 mm
Explanation:
Capillary movement involves the movement of liquid up through a capillary tube.
Looking at the question, we can see all the various diameters of the capillary tube are involved.
Note that, that the narrower the diameter of the capillary tube, the better the capillary action of the liquid (the liquid rises more now than then).
Fluorine, chlorine, iodine (the halogens), oxygen, sulphur, hydrogen
The atoms which make up the ion are covalently bonded to one another. 19) It is possible for a compound<span> to possess </span>both ionic and covalent bonding<span>. a. If one of the </span>ions<span> is polyatomic then there will be </span>covalent bonding<span> within it.</span>
Answer:
nitrogen oxides and sulphur oxides
Explanation:
Factors responsible for antropogenic pollution are:
- burning of fossil fuels
- deforestation
- mining
- sewage
- industrial effluent
- pesticides, fertilizers, etc.
The primary air pollutants released from burning of fossil fuels are oxides of nitrogen, sulfur oxides and carbon monoxide.
Out of which the main pollutants that are responsible for acidic precipitation are oxides of nitrogen and sulfur oxides.
Sulfur oxides and Oxides of nitrogen reacts with moisture present in the air to form sulfuric acid and nitric acid respectively.
These acids get mixed with rain and cause acidic precipitation.
Therefore, the correct option is oxides of nitrogen and sulfur oxides.
