Answer:
ummmm... whats this supposed to mean? any answer choices
Explanation:
Answer:
NH3 is polar due to the bonds between nitrogen and hydrogen which have different electronegativity and due also to its asymmetrical shape.
Explanation:
NH3 is polar as there are 3 dipoles in the ammonia molecule that do not balance each other out.
Considering the N-H bond which is polar because N with an electronegativy of 3.0, is more electronegative than H, with an electronegativity of 2.1. The is overall asymmetrical shape of NH3
means that the dipoles remains unbalanced and do cancel out each other making the NH3 polar.
Pseudo-science is not considered real science because it is not testable.
Answer: Option A
<u>Explanation:</u>
Pseudoscience primarily includes beliefs, theories or practices that are somehow incompatible with the scientific facts. The pseudoscience can’t be tested on the basis of science.
Let’s take an example of astrology. Some people believe that stars and other celestial bodies draw a significant impact on their life i.e. Good or bad thing it's just because their stars are working either in a positive or negative manner.
But, this belief doesn’t have any well-proved or authentic background over which the whole concept can rely on. Hence, pseudoscience is not taken as a real science as a lack of strong proves.
