Polar molecules (with +/- charges) are attracted to water molecules and are hydrophilic. Nonpolar molecules are repelled by water and do not dissolve in water; are hydrophobic.
In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
Answer:
.92 A = Is
Explanation:
Is = 
We're solving for Is, so plug in all the other given numbers.
Vp = 230 V
Ip = .020 A
Vs = 5.0 V
Is = 
= .92 A
