<span>Science involves Observation. With out observation then you do not have science. So, if you were studying plants for instance, you would be looking at the plants and drawing conclusions based upon your observations and experiments (and the observation of the experiments). Something that is not scientific is the theories of how this world came about. Neither the evolutionist view or the Creationist view is scientific, no one can observe what happened thousands of years ago. The theories of how this world came about are merely faith based. Atheist put their faith in billions of years and Christians to a higher power. So that would be an example of something that is not scientific.</span>
Answer:
B. The student conducted the reaction in an open beaker, which allowed one of the products, a gas, to escape.
Explanation:
Based on the law of conservation of mass, matter is neither created nor destroyed during the course of a chemical reaction.
By this premise, the mass of reactants and products must remain the same during the course of a reaction.
- Here we find that this is not the case.
- The mass of the product reported is less than the mass of the reactants.
- The problem is that the mass of the gas bubbles produced during the course of this reaction was not accounted for.
- This leaves a mass deficit already
Answer:
C.
Explanation:
Exothermic means the energy of products is lower than energy of reactants. Transition state will always be the highest energy among the two.
Answer:
The Sun is the primary source of energy that influences any planet's temperature, including Earth. The amount of energy received from the Sun is called insolation; the ratio reflected is called the albedo.
