how many properties of water are there
5
what is a solute
the substance being disolved in the liquid
what is a compound
when two or more elements are combined
what is a macromolecule
a very large molecule composed of carbon and other atoms
chemical reactions always involve what
breaking or forming between bonds
what is cohesion
water molecules are atracted to themselves
what is a solvent
the substance doing the dissolving
what is an ionic bond
when electrons move to one and other, this is a strong bond
what are carbohydrates known as and what are they made of
they are made of 1carbon 2 hydrogen 1oxygen, they are known as sugars and give structual suport and quick energy. also known as CHO
what are energy releasing reactions
spontaneuos
what is adhesion
water molecules are atracted to other polar molecules
what are acids
solutions with a ph of less than 7, taste sour, nutralize bases, corrode metal and have high concentrations of
H+ ions
what is a covalent bond
when electrons are shared and orbit around atoms, this is a strong bond
what are nucleic acids
made of nucleotide monomers they store geetic info in cells in the form of a code = DNA, RNA. also known as CHONP
what are energy absorbing reactions
not spontaneous
what molecule and what bonds are in water
polar molecules and hydrogen bonds
what is bases
solutions with a ph of more than 7, slippery, neutralize acids, also known as alkaline, and high concentration of OH+ ions
what is a hydrogen bond
when 2 slightly charged molecules are attracted to each other, this is a weak bond
what are lipids
lipid are fats, steroids, oils, and waxes and are mostly comprised of carbon, hydrogen and oxygen. lipids provide long term memory storage and are also known as cho
what is sythesis
when molecules are being joined together
what are the properties of water
water can creep up thin tubes, water has high surface tension, water has a high heat of vaporization, water resists temperature change, water expands when it freezes
what is the universal solvent
water
molecules make up what?
compounds
what is protein
it is made of carbon hydrogen oxygen and nitrogen atoms. proteins are composed of long chains of amino acids and it is also known as CHON
what is decomposition
when molecules are broken apart
