The rule is for every 1 gram of sodium chloride you add .1 degree F to the boiling point up too 100 grams or 212.5 degrees F
The correct option is A.
The lanthanides are a group of transition metals which are found in the periodic table. They are fifteen in number and they are all radioactive. They are usually refereed to as the 'rare earth' metals because they are not common. Lanthanides have fairly high melting points.
Sn + 2Cl2 ---> Sn⁺⁴Cl⁻¹4
2 mol 1 mol
2.85 mol x
x=(2.85*1)/2=1.425≈1.43 mol SnCl4
Modern periodic table is arranged on the basis of element's increasing "Atomic numbers"
Hope this helps!
The action that would most likely lead to. Decrease in volume is decrease in temperature.
