Answer:
In the case of water, an object with a density less than 1 g/cm3 will float. The closer its density is to 1 g/cm3, the more of it will sit below the water level.
Explanation:
Whether an object will float or sink is dependent on its density, and on the density of the liquid it is placed in.
Answer:
Here's what I get.
Explanation:
Ba is element 56. Its electron configuration is
1s² 2s²2p⁶ 3s²3p⁶ 4s²3d¹⁰4p⁶ 5s²4d¹⁰5p⁶ 6s²
That's a lot of writing.
To lessen the work, chemists have developed the noble gas notation.
The core electrons of Ba (listed in boldface) have the same electron configuration as Xe, the noble gas found two atoms earlier in the Periodic Table.
Chemists replace the core electron configuration with the symbol of the corresponding noble gas.
The noble gas notation for Ba becomes
Ba: [Xe]6s².
Answer:
C
Explanation:
Cyclohexane is a cycloalkane with the molecular formula C₆H₁₂. Cyclohexane is non-polar.
When acids react with water, H ions are released which then combine with water molecules to form H₃O⁺
