Because the atom isn't a isotope. The electrons, (negative charge) , and the protons, (positive charge), balance each other out.
<span>C. Their direction of motion is south and north. </span>
This is an acid-base reaction where HF is the acid and H2O is the base (it's amphoteric and can be an acid or a base). The products would then H3O+ (the conjugate acid) and F- (the conjugate base). Now, we can simply construct a reaction using the found products and reactants. This acid-base reaction would be HF + H2O <--> H3O+ + F-.
Hope this helps!
78 protons are found in platinum(pt).
