An oxygen atom has a much stronger attraction for electrons than a hydrogen atom (why?)
because single proton ang oxygen
bakit hindi kasing strong ng hydrogen bonds ang ionic bonds
???
what tyoe of hydrogen bond?
Water is able to form multiple hydrogen bonds that accounts for many of its special properties.
multiple gydrogen bonds
[Cohesion, Adhesion & Surface Tension]
holds water molecules to other polar substances
Adhesion
holds water together [Cohesion, Adhesion & Surface Tension]
cohesion
caused by cohesion of water to itself and lack of adhesion to air [Cohesion, Adhesion & Surface Tension]
surfce tension
Water has an extremely [low/high] specific heat
high
[Heat vs. Temperature]
the total kinetic energy stored in an object (related to mass)
heat
[Heat vs. Temperature]
the average kinetic energy (mass doesn’t matter)
temp
water is a universal???
solvent
[solution/solute/solvent]
dissolved substance
solute
[solution/solute/solvent]
evenly distributed mixture of 2 or more substances
solution
[solution/solute/solvent] Dissolving substance (usually water)
solvent
types of solutes [hydrophobic/hydrophilic]
substances do not form Hydrogen bonds with water (oils, membranes, some proteins, etc.)
hydrophobic
types of solutes [hydrophobic/hydrophilic]
substances form Hydrogen bonds with water (ions, sugars, cellulose, some proteins
hydrophilic
Homogeneous (hydrophobic/hydrophilic)
hydrophilic
Heterogeneous ( hydrophobic/hydrophilic)
hydrophobic
