Answer:
I think that it is II and IV.
I'm not positive so don't count on it, but i'm bout to be in 11th grade and I remember my chemistry teacher showing us this video so there is a video on you tube where he explains in.
Explanation:
I'm sorry if this is useless, but lemme know what you get for the answer. Good Luck:)
Cl-3.16, S-2.58, Na-0.93, Rb-0.82
Answer:
No
Explanation:
Hello,
Since the sealed glass container is isolated (closed system) no escape of boiled water (steam) was presented, so it is obvious that the alchemists were wrong, it is impossible that the water turns into "earth" because it has components that water does not have by itself (metallic and nonmetallic ions and molecular compounds) that is why the solid residue could have come from suspended solids or simply solids that were initially dissolved and due to the boiling of water, they remained at the bottom of the flask. Nevertheless, the experiment done by Lavoisier was more precise because the conclusion based on the initial and final masses, accounts for the boiling process; besides, the mass agreement substantiates that no mass was removed due to the isolation of the flask.
Best regards.
Answer:
180 degrees
Explanation:
sp hybridization generates orbitals that overlap linearly, generating a straight line. This leads to an angle measurement of 180 degrees.
