<u>Answer:</u>
Carbon and silicon both are tetravalent elements as compared to germanium, tin, and lead which are divalent.
That's because Ge, tin, and Pb show inert pair effect and has a greater nuclear effective charge on the 's' electrons due to poor shielding effect. .That's why these elements are not able to share their valence electrons while carbon and silicon does and show "catenation" which is the ability to form long chain molecules.
i think the answer is C3H8O
Answer:
is the total displacement (volume) of the submarine.
Explanation:
Mass of water carried by submarine at 1000 ft depth = m = 2100 kg
The density of seawater at 1000 ft depth = d = 
Volume of the water displaced = V= ?
Total displacement of the submarine = Volume of the water displaced = V
is the total displacement (volume) of the submarine.
1 Science is certain about ending up with the actual explanation while pseudoscience does not ensure that.
2
Science is involved with a set of principles to work, while pseudoscience is not operated in a unique method.
3 Science is based on tangible or perceptible evidence, but pseudoscience could be based on some superficial or outlandish concepts.
4 Science result the truth while pseudoscience results the myth.
Trick question: you just stated everything in the beakers.
