Answer:
Lower
Explanation:
Surface tension occurs because molecules at the surface do not have molecules above them, so they cohere more strongly to their neighbours.
The stronger cohesive forces make it more difficult to move an object through the surface than when it is beneath the surface.
The attractive forces in water are strong because of hydrogen bonding.
A hexane molecule is nonpolar, so the only attractions are the weak London dispersion forces.
The cohesive forces at the surface are much lower than those in water, so the surface tension of hexane is lower than that of water at the sane temperature.
Answer is: <span> 1.4 × 10-10 m
</span>pH = 9.85.
[H₃O⁺] = 10∧(-9.85).
[H₃O⁺] = 1.4·10⁻¹⁰ M.
pH (potential of
hydrogen) is a numeric scale used to specify the acidity or basicity <span>an aqueous solution.
</span>If pH is greater than
seven, solution is base and if pH is equal seven, solution is neutral and if pH of solution is less than seven, than is acidic.<span>

Answer:
Scientists consider human to be" carbon creatures" because carbon atoms form the backbone or foundation of pretty much the essential biological molecules floating around in our bodies (except water, of course.) All in all, scientists can consider humans to be " carbon creatures" because our skin, hair and cells are all made out of molecules that contain huge amounts of carbon.
Hope this helps! God bless!
True.
without natural selection darwin’s theory would not make sense :))
The answer is false
Iron and nickel is more dense
