the answer is there is a one-to-one ratio of potassium ions to iodide ions.
- (k) belongs to alkali metals in group (1a) that contains (1) electron in the outermost energy level, whereas, (i) is from halogens in group (7a) that contains (7) electron in the outermost energy level.
- to achieve stability, both atoms tend to reach the nearest noble state (outermost level occupies 8 electrons). therefore, (k) loses its outer electron and gives it to (i) which now has a completely filled outer level and an ionic bond is formed between the two.
- the valency (number of electrons lost, gained or shared) of both atoms is equal ”monovalent” which means one-to-one ratio..
a tropical cyclone's primary energy source is the release of the heat of condensation from water vapor condensing at high altitudes, with solar heating being the initial source for evaporation.
the secret energy source of a hurricane is the large latent heat of water.
tropical cyclones are like giant engines that use warm, moist air as fuel. that is why they form only over warm ocean waters near the equator. the warm, moist air over the ocean rises upward from near the surface.as the warmed, moist air rises and cools off, the water in the air forms clouds.
correct answer: is c, decreasing the temperature.
