Ca ionises into Ca^2+. Ca^2+ will be attracted to O^2- ions in the water, since opposite charges attract. (Hydrogen in water forms H^+)
From Boyle's law the volume of a fixed mass of a gas is inversely proportional to the pressure at a constant absolute temperature. Thus; K = PV Hence; P1V1 =P2V2 0.5 × 24 = 4× P2 P2 = 12/4 = 3 atm Therefore; the pressure will go from 24 atm to 3 atm
Answer:
1: CO2 cycle
2: soil respiration
3: in soil repiration grass regenerates and is ready for gazing, the carbon will be sequestered again when the animals return. then CO2 is released into the atmosphere.
Answer:
ClO₄⁻
Explanation:
When an ion is hydrated it is surrounded by water molecules, thus, as small is the ion, more molecules may surround it, and it will be more strongly hydrated. In this case, the Cl is small than the S atom, because Cl is from group 17, and S from group 16, and Cl has more valence electrons, which will be more attracted to the nuclei.
So, ClO₄⁻ will be more strongly hydrated.
Answer:
The scientist have developed to classify organisms because the living things with similarities can put into groups, which can further make easy to understand the relationship between them.
Explanation:
The scientist have classified organisms in different groups which can make their study easier. In this manner the organisms with same character will be in same group and their relationship and behavior with themselves as well as with others can be studied easily. It will make things less confusing. In this way the inheritance and genetic behavior can also be studied easily. This classification are based on various other categories like structure, function and also relationship with others.
