Hydrogen hydroxide

Dihydrogen monoxide

• forms 70% of animals' bodies and 90% of plants..

• inorganic compound- a substance that does not contain both carbon and hydrogen

Who am I?

Bonding<3

Polarity

• oxygen is electronegative, region with the oxygen has a partial negative charge.
• hydrogen is electropositive, region with the hydrogens has a partial positive charge

• A molecule with such a charge difference is called a dipole.

• chemical bonding- two hydrogen atoms and one oxygen atom to form the H2O molecule.
• colourless, odourless, tasteless
• covalent bond- the sharing of electrons between two or more non-metal atoms

Structure

BIPOLAR

• In a liquid state, the water molecules are in constant motion which causes them to come into contact frequently.

Timeline

• From this, weak and temporary hydrogen bonds are formed. Once one water molecule comes close to another, one’s hydrogen atom and the other’s oxygen atom form a bond.
• This hydrogen bond is the main cause of water’s properties.

Hydrogen Bonding

My Properties

• Dipole nature causes ionic/molecules in substances to disassociate.

Solvent of Life

LIFE

NUTRIENTS=MONEY

• Caused by hydrogen bonding
• Strong attraction between a hydrogen atom in the water molecule to be attracted to an oxygen atom in another water molecule

Cohesion

• Caused by covalent bonding
• Tendency of water molecules to be attracted to other substances

Adhesion

• uses adhesion and cohesion
• the ability of water, or any liquid, to flow against gravity up a narrow poreous tube

Capillary Action

• Caused by hydrogen bonds
• Takes a lot of energy for heat to be absorbed
• As heat is absorbed,hydrogen bonds are broken and water molecules can move freely.

Specific Heat Capacity

Water Boiling

My References

• The Basilisk Lizard usually leaps from trees and runs across water to safety whenever its life is endangered.
• Surface Tension- water molecules at the top of water have a stronger bond because of an extra hydrogen bond.

Basilisk Lizard (akaJesus Christ Lizard)

Jellyfish

• Made of 95% water; cannot survive without it
• Water is its habitat; lives in ocean

My References

• Non-polar solvent; will not dissolve minerals

• Poor solvent for transporting minerals

• Even lower specific heat capacity (1800 J/Kg Co

• Much lower specific heat capacity (2400 J/Kg Co)
