Answers for this questions are:
1)
trough - lowest point of the wave.<span>
2) crest - highest point of wave.
3) amplitude - distance from rest position to
the crest or thoughs.
4) wavelenght - distance from two consecutive
crest or troughs.
<span>5) rest position - the flat line running through
middle of the wave.</span></span>

The energy of the 434 nm emission line is 4.58×10¯¹⁹ J (Option A)
<h3>Data obtained from the question </h3>
The following data were obtained from the question:
- Wavelength (λ) = 434 nm = 434×10¯⁹ m
- Planck's constant (h) = 6.626×10¯³⁴ Js
- Speed of light (v) = 3×10⁸ m/s
- Energy (E) =?
<h3>How to determine the energy </h3>
The energy of the 434 nm emission line can be obtained as follow:
E = hv / λ
E = (6.626×10¯³⁴ × 3×10⁸) / 434×10¯⁹ 9.58×10¹⁴
E = 4.58×10¯¹⁹ J
Thus, the energy of the 434 nm emission line is 4.58×10¯¹⁹ J

Answer:
Explanation:
For one B2 molecule 3 A2 molecules are reacting means,
the ratio is 1:3
Out of 126 molecule = 126/3 =42 molecules are required for the reaction,
therefore the 54-42= 10 molcules of B2 will reamin in the end of reaction.
No, their specific heats are different. For water, and ice
