Naturalistic observation is a technique under which observation of the subject is done in its natural environment.
Usually this technique is used when lab research will be unreasonable.
How Does Naturalistic Observation Work?
This technique may be used just because people's responses may be more effective when they are in their comfortable environment than when they are in a lab for research purposes.
Sometimes the result of the research are more effective when the behaviour is observed in an exactly moment when it happens. By watching how people respond to certain situations and stimuli in real-life, psychologists can get a better idea of how and why people react.
All I know is that the answer to number 1 is Mexico sorry
Answer:
The chemical reaction of burning methane and oxygen is as follows;
(A (the entire green box): chemical equation
B (the blue box): reactants
C (the arrow): reacts to form
D (the purple box): products (This is the chemical equation)
Here, the reactants are methane and oxygen, one mole of methane reacts with 2 moles of oxygen present in the air;
and the products thus formed are one mole of carbon dioxide and two moles of water.
So here, methane and oxygen reacts to form carbon dioxide and water.
