Answer:
Reactants.
Step-by-step explanation:
The equation for the reverse reaction is
Z + Q ⟶ X + Y; ΔH < 0
A negative ΔH indicates that the energy has been given off.
The products X + Y are at a <em>lower energy level</em> than the reactants Z + Q, and the excess energy has been <em>transferred to the surroundings</em>.
The lines are violet and blue respectively.
<h3>What is the energy?</h3>
We know that the energy of the photon could be obtained by the use of the equation;
E = hf
E = energy
h = Plank's constant
f = frequency
For the first line;
E = 6.6 * 10^-34 Js * 3.45 x 10^14 Hz = 2.3 * 10^-19 J
Given that;
E = hc/λ
λ = hc/E
λ = 6.6 * 10^-34 * 3 * 10^8/2.3 * 10^-19
λ = 8.61 * 10^-7 m or 861 nm
The color is violet
For the second line;
E = 6.6 * 10^-34 Js * 6.53 xx 10^14 Hz
E = 4.3 * 10^-19 J
E = hc/λ
λ = hc/E
λ = 6.6 * 10^-34 * 3 * 10^8/4.3 * 10^-19
λ = 4.60 * 10^- 7 m or 460 nm
The color is blue

Explanation:
Reducing agent
Reducing agent is an element or compound that loses or donates an electron to another chemical species in a redox chemical reaction. Since the reducing agent is losing electrons,it is said to have been oxidized.
