Answer:
molarity is moles/L so take the 3.48 and divide it by 4.1L
and get 0.848... and need to keep your answer to 2 digits as that is th emost precise measurement you have (the 4.1L)
so 0.85mol/L
Explanation:
Answer:
C. Base.
Explanation:
Hello there!
In this case, according to the given information, it turns out convenient for us to realize that the concept acid and base we should use here is based off the Bronsted-Lowry one, which says that an acid is a hydrogen donor. In such a way, since water accepts one H ion as it goes to H3O⁺, we infer it is C. Base and the H2S the acid.
Also, we can tell HS⁻ is the conjugate base and H3O⁺ the conjugate acid.
Regards!
The answer is the option (3) The geometric shape of a CH4 molecule
distributes the charges geometrically. the CH4 is a tetrahedral with the
Carbon atom in the center and the four H atoms in the vertices of the
tetrahedral. The C-H bond angles are all identical which makes the
molecule perfectly symmetrical and so any dipolar moment will cancel
making the molecule non polar.
Answer: 2 kg/L or 2 g/mL
Explanation:
litres are a cubic measure. “Cubic litres” is redundant at best, potentially confusing.
