Answer:
Pseudoscience
Explanation:
Predicting the future based solely on the position of the planets is an example of <u>pseudoscience</u>.
<em>Pseudoscience is a body of knowledge that is not based on the scientific method but on some unverifiable/unprovable claims.</em>
Predictions about the future can only be valid if it is based on the scientific method, not just about the position of the planet. The scientific method involves observation, hypothesis formulation, testing of the hypothesis through repeatable experiments, and arriving at conclusion.
Any other statement or belief that is not based on these procedures is said to be pseudoscientific.
Answer:
A.
as the sum of the energy of the products and the energy of the reactants.
Explanation:
Because the sun is on top of the energy.
Answer:
The world’s hot deserts are located between 15° and 30° north or south of the equator, where the air is subsiding or sinking air
Explanation:

Answer:
when they have satisfied the octet rule naturally or through bonding to obtain full valence shells
Explanation:
Generally, most atoms of an element are unstable because they have a void in their electron shell to fill, hence, they need to react with other elements to fulfil this task of octet.
Octet rule states that atoms of elements engage in reactions to form compounds so they can have eight (8) valence electrons in their shell. Noble gases e.g argon, neon etc. are elements that have naturally satisfied this octet rule by possession of 8 valence electrons in their shell. Other elements that do not have this naturally becomes reactive and enter bonding with other atoms to obtain full valence shells.
Answer:
releases, increase
Explanation:
The total energy of products in an Exothermic reaction is less compare to
total energy of the reactants. As a result of these the enthalpy becomes negative, then there is release of heat to the surroundings, which increase the energy of the immediate surroundings inform of heat. Hence the system release energy while the surroundings energy increase.
