1 mole ----------- 6.02 x 10²³ atoms
? mole ---------- 24.08 x 10²³ atoms
moles B = ( 24.08 x 10²³) x 1 / 6.02 x 10²³
moles B = 24.08 x 10²³ / 6.02 x 10²³
= 4 moles
Answer B
hope this helps!
Answer: C (Option 3)
Cs < Cl < F
Cesium is the least electronegative atom.
Fluorine is the most electronegative atom.
I believe the correct answer from the choices listed above is option D. Catalysts lower the activation energy of a chemical reaction. It <span>is a substance which speeds up a reaction, but is chemically unchanged at the end of the reaction. It provides another pathway for the reaction to occur.</span>
Considering that scientific notation has to move the decimal over so there is only one digit in the Tens place, that is the scientific notation.
Its a base
as Na+ dissociates in the water and it has no basic nor acidic properties its neutral]
but the F- that also dissociates has certain basic properties
hope that helps
