Does this look correct? Thx!

Write the balanced equation for the reaction between solid copper and silver nitrate, that produces solid silver and copper(II) nitrate in solution. Include your experimentally determined mole ratios for the copper and silver atoms as coefficients.

answer: 1Cu 2Ag+ -----> 1Cu+2 2Ag

No, it isn't correct but mostly because you omitted plus signs.
Cu + 2Ag^+ ==> Cu^+2 + 2Ag
The 1 isn't needed; writing Cu and we understand there must be 1 there or we wouldn't have written Cu. Anything other number than 1 must be typed in.
