If your equation is <span>Cu+NO^- 3-->Cu^2+NO, then the answer is
</span><span>2 Cu + 1 NO3{-} → 1 Cu^{2+} + 3 NO
</span>
To check if it is balance, this is the solution:
2- Cu- 2
3- N -3
3- O -3
Answer:
The glow stick in hot water will be brighter
Explanation:
The glow stick in hot water will be brighter than the glow stick in cold water because the heat from the hot water will cause the molecules in the glow stick to move faster. The faster the molecules move in the glow stick, the sooner and brighter the reaction will be. The cold water will cause molecules to move slowly and it will take longer for the reaction to occur, which will also make it less bright.
Answer:
343 m/s
Explanation:
Velocity Formula (Wave): v = fλ
<em>v</em> - velocity
<em>f</em> - frequency
<em>λ</em> - wavelength
We are given <em>f</em> = 23.0 and <em>λ</em> = 14.9. Simply plug it into the formula:
v = 23.0(14.9)
v = 342.7
v ≈ 343
