Answer:
Explanation:
We have two pressures, two temperatures, and one volume.
This looks like a question in which we can use the Combined Gas Law to calculate the volume.

2.626984127 m
<h2>
Explanation:</h2><h2>
</h2>
You have to know the equation that relates wavelength, frequency, and velocity (it's like speed but a bit different).
v = f x λ
where:
v = velocity
f = frequency
λ = Wavelength
Rearrange to make λ subject:
λ = v / f
We've been given 331 as the speed, 126 as the frequency. Sub it into the equation:
331 / 126 = 2.626984127 m
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
55= No (1/2)^55/57
55= No (1/2)^3.9
55= No (1/2)^4
55= No (1/16)
No= 880 g
