The property is its polarity (or hydrogen bonds)
Answer:
it opposes motion. the object would continue to slide forever if not stopped by another object.
Ionic charge = +4
To answer this we look only at the protons and electrons. Because there are 4 more protons than electrons we know that this ion has 4 less electrons than it would need to have to have a neutral charge. Therefore, the ionic charge is +4
Answer:
Ionic bond is bond between a metal and non metal , metallic bonding happens between positive metals ions and negative electrons in a metal
Explanation:
ionic Bond is the transfer of electrons between a metal and non metal due to strong electrostatic force of attraction between positive metal ions and negative non metal ions
in metallic bonding , there is a force of attraction between positive metal ions and the sea of electrons surrounding it
There are different techniques to reduce friction, similar to 1. Cleaning the surfaces 2. Including lubricants 3. expanding the temperature 4. wetting the surface 5. expelling polluting influences. Egyptian could have moved the square through water, which would be Fluid Friction, and makes it less demanding to move.
