Answer:
glycerol because it is more viscous and has a larger molar mass than water.
Explanation:
Viscosity depends on inter-molecular interactions.
The predominant inter-molecular force in water and glycerol is hydrogen bonding.
Hydrogen bond is an electrostatic attraction between two polar groups in which one group has hydrogen atom (H) and another group has highly electronegative atom such as nitrogen (like in this molecule), oxygen (O) or fluorine (F).
B) less
As if the atom has more electrons than protons it is negatively charged
Answer:
Boron has 3 valence electrons
A balanced chemical reaction obeys the law of conservation of mass, because the same number of atoms of each element must appear on both sides of the equation for the reaction … , and in any actual reaction, the same exact atoms will be found on both sides of the equation.
Answer:
C. Hair dryer
Explanation:
Alternating Current
The other kind of electricity is called alternating current, or AC. Power plants produce this
type of electricity. It is carried by large power lines from the plant to your home. When you
plug a TV, a lamp, or a hair dryer into the wall socket, you are using this type of electricity.
