<span>1. A scientific hypothesis can become a theory if the hypothesis is tested extensively and competing hypothesis are eliminated. A scientific hypothesis is a proposed explanation made on the basis of reasoning without any assumption. For hypothesis to be termed a scientific hypothesis, it has to be something that can be supported or refuted through carefully crafted experimentation or observation.
2. A preliminary untested explanation that tries to explain how or why thing happen in the manner observed is a scientific hypothesis. A primary trait of a hypothesis is that something can be tested and that those tests can be replicated. A hypothesis is often examined by multiples scientists to ensure the integrity and veracity of the experiment. The process can take years, and in many cases hypothesis do not go any further in the scientific method as it is difficult to gather sufficient supporting evidence. </span>

<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>
