Explanation:
Answer: Option (a) is the correct answer.
Explanation:
Elements which are most electropositive or electronegative are the most reactive in nature. Therefore, they are active.
Elements of group 1 are also known as alkali metals. Elements of group 1 are lithium, sodium, potassium, rubidium, cesium, and francium.
All these are highly electropositive in nature and thus, are active. These are placed at the top left column of periodic table.
Thus, we can conclude that out of the given options, the most active metals on the periodic table are found on the lower left.
The molar solubility is the Pb ions present. PbCO3 dissociate to form Pb ions and CO3 ions
Ksp 7.40x10^-14 is equal to (Pb ions) (CO3 ions)
Pb ions correspond to CO3 ions
(pb ions)( Pb ions) is equal to 7.40x10^-14
therefore Pb ions is square root of 7.4x10^14 which is 2.27x10^-7m
In g/l is (2.27x10^-7) x 267(RFM of PbCO3) which is 6.06x10^-5 g/l
We are most likely to find water in the form of gas in the atmosphere.
Answer:
kinetic energy
Explanation:
Thermal Energy, Temperature, and Heat. Thermal energy is kinetic energy associated with the random motion of atoms and molecules.
