Metallic and non-metallic properties
Non-metallic property increases across a period and decreases down the group due to the same reason due to an increase in nuclear attractive force.
I hope this helps
Answer: 7 atm
Explanation:
According to Dalton's Law, the total pressure is the sum of all the individual gas pressures
Hence, Ptotal = P1 + P2 + P3
Since, Gas A = 2 atm
Gas B = 1 atm
Gas B = 4 atm
Ptotal = (2 + 1 + 4) atm
Ptotal= 7 atm
Thus, the total pressure of the gas mixture is 7 atmosphere.
Answer: Difference in properties of these two compounds are because one compound is covalent and the other one is ionic.
Explanation: LiCl is an inorganic compound having high electronegativity difference between the two elements and hence, is termed as an ionic compound.
is a organic compound formed by the sharing of electrons between the elements, hence is termed as a covalent compound.
Hence, the properties are different because one of the compound is covalent and other is ionic.
