What is the energy of the electron in a helium ion with a charge of +1 in an orbit with a value of n=4? Use k=2.179×10^−18 J.
Report your answer with three significant figures.

Sugar and water are chemically combined.(a solution is chemically combined while a mixture is mixed together without bonding the molecules)

Ch4 is nonpolar and insoluble in water. since all of the hydrogen atoms are evenly spread around the carbon atom even through the c h bond is polar all the poles cancel each other out.

D. is the answer hope that you
