Answer: The ratio of atoms of potassium to ratio of atoms of oxygen is 4:2
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed, and remains conserved. The mass of products must be same as that of the reactants.
Thus the number of atoms of each element must be same on both sides of the equation so as to keep the mass same and thus balanced chemical equations are written.
K exists as atoms and oxygen exist as molecule which consists of 2 atoms. The ratio of number of atoms on both sides of the reaction are same and thus the ratio of atoms of potassium to ratio of atoms of oxygen is 4:2.
K= (1/2) m v^2
so 0.5*0.145*<span>1281.64=92.92J of KE</span>

Answer:
Barium - Ba
Barium is a chemical element with the symbol Ba and atomic number 56. It is the fifth element in group 2 and is a soft, silvery alkaline earth metal. Because of its high chemical reactivity, barium is never found in nature as a free element.
Symbol: Ba
Atomic mass: 137.327 u
Electron configuration: [Xe] 6s2
Atomic number: 56
Van der Waals radius: 268 pm
Discoverers: Humphry Davy, Carl Wilhelm Scheele
As the water heats the components of the crude oil begin to separate when it reaches a certain stage. C. Boiling Point is that stage.
Hope this answer helps you.
