WebFeb 7, 2024 · Characteristic tests: i. CO2: Pass the CO2 gas through lime water. It will turn lime water milky. This occurs due to formation of calcium carbonate. ii. SO2: Pass the SO2 gas through acidified potassium dichromate solution (orange in colour). The solution changes to green in colour due to formation of Cr2(SO4)3. WebMay 1, 2013 · 1.

In water, hydrogen bonding causes linkages in the water molecules which result in the boiling point of water is more than that of the other compounds. Ammonia has a higher boiling point than PH 3 because there is hydrogen bonding in NH 3 but not in PH 3. WebTraits can include characteristics such as height, eye color, and intelligence, as well as disorders like schizophrenia and autism spectrum disorder. In scientific terms, heritability is a statistical concept (represented as h²) that describes how much of the variation in a given trait can be attributed to genetic variation. npr morning edition october 12 2021
