1. Make an observation : My toaster doesn't toast my bread

2. Ask a question : Why doesn't my toaster work?

3. Form a hypothesis : My coffeemaker works when plugged into the outlet

4. Make a prediction : If something is wrong with the outlet, then my coffeemaker also won't work when plugged into it

5. Conduct an experiment : I plug my coffeemaker into the outlet

6. Analyze the results : There is something wrong with the electrical outlet

Explanation:

The solution to the problem is as shown above.

A scientific method follow a methodical way of critically carrying out an inquiry into an observation.
Firstly, an observation is usually made with our senses. Here the researcher observes that the toaster does not toast his bread probably after a long wait.
He then proceeds to ask why the toaster does not work.
To investigate this, the forms a hypothesis. A hypothesis is a scientific guess. It is a tentative proposition about an investigation.
The researcher then makes a prediction about the outlet that might be faulty.
With this background, he goes on to carry out an experiment to substantiate his findings. This is seen when he plugs the coffeemaker into the outlet.
From the analysis of result, he sees that that something is wrong with the outlet.

Given the equation for a system at equilibrium:

zlopas [31]

Answer: 1. $NH_3$ increases.

Explanation:

Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.

For the given equation:

$N_2(g)+3H_2(g)\rightleftharpoons 2NH_3(g)+energy$

If the concentration of $N_2$ is increased , according to the Le-Chatlier's principle, the reaction has to shift to right or forward direction. In order to do that the concentration of products has to increase.
