Pseudoscience refers to belief, theories and practices that claims to be scientific but which have no basis in scientific facts.
Pseudoscience has many traits two of which are:
1. It is based on dogma and uncritical belief. Counter evidence might draw hostility from pseudo scientists.
2. There is usually suppression or distortion of data. Pseudo scientists typically perform selective data gathering, in which they only gather and consider favorable data that support their claims. <span />
We know, silicon is a natural semi-conductor, if manufacturer has lost its supplier then they can look for another element which is quite similar to silicon in electronic configuration.
We should go down the group, next element in 14th group is "Germanium" so we can use that for that purpose.
In short, Your Answer would be "Germanium"
Hope this helps!
I think a good strategy for these kind of problems is to just choose the atom with the highest mass number. At any rate, the answer actually is (and I guessed it as) (2) Francium-220. It has a half life of about 30 seconds.
Answer:
This is considered a hypothesis because it hasn't been confirmed. It is just a guess.
Explanation:
A hypothesis is a limited explanation of a phenomenon; a scientific theory is an in-depth explanation of the observed phenomenon. Law is a statement about an observed phenomenon or a unifying concept, according to Kennesaw State University. However, Newton's law doesn't explain what gravity is, or how it works.
Answer:
Volume of acid in the solution, 53.87 mL
Explanation:
This can be solved with a simple formula
(Volume of solution which is acid / Total volume) . 100 = % acid
(Volume of solution which is acid / 341 mL) . 100 = 15.8
Volume of solution which is acid / 341 mL = 0.158
Volume of solution which is acid = 0.158 . 341 mL
Volume of solution which is acid = 53.87 mL
