<h3><u>Answer;</u></h3>
Decrease in pressure
<h3><u>Explanation;</u></h3>
- If the pressure of a system is increased, the reaction will shift toward the side with fewer moles of gas, whereas when the pressure of a system is decreased, the reaction will shift toward the side with more moles of gas.
- In this case; <em><u>If the pressure of the system with the above reaction decreases, the reaction will shift to the left. The reactants side has more moles of gas, so the reaction will shift toward the direction of the reactants.</u></em>
Electron transitions from higher to lower energy levels cause emission of energy in the form of electromagnetic waves, each with their own specific wavelength. Because the energy levels of elements are quantized, each transition has a specific energy difference. The collection of these transitions makes up the emission spectrum and each spectrum is unique to a specific element, allowing identification.

Answer:A theory is a well-substantiated explanation of an aspect of the natural world that can incorporate laws, hypotheses and facts.
Explanation:
Molecules move from areas of low concentration to areas of high concentration. This requires the use of energy.
