Which is NOT a reason water is important to life?

• It takes a lot of heat (cooling) to change the temperature

• It is polar, which makes it an excellent solvent

• It can react with chemicals, splitting them up so we can get the nutrients we need out of them.

• It serves as a cushion for some of our main organs

• It changes shape to allow chemicals to dissolve in it.

Vinegar is an

• acid

• base

• pH neutral

When acids react, they......

• donate H+ ions

• donate H- ions

• receive H+ ions

• receive H- ions

When bases react, they......

• donate OH+ ions

• donate OH- ions

• receive OH+ ions

• receive OH- ions

What is a buffer

• a weak acid or base our body produces to protect us from stronger acids and bases.

• a weak acid or base we drink to counteract a stronger acid or base.

• cells in our bodies that attack and destroy acids and bases

• cells in our bodies that are not affected by acids or bases form a protective barrier from other cells that are affected by acids or bases.

what is dehydration synthesis

• the joining of two or more monomers, with a water molecule as a product

• when water is made in a laboratory

• splitting a water molecule into oxygen and hydrogen

• when a polymer is split into monomers by adding a water molecule to each one.

what is hydrolysis

• the joining of two or more monomers, with a water molecule as a product

• when water is made in a laboratory

• splitting a water molecule into oxygen and hydrogen

• when a polymer is split into monomers by adding a water molecule to each one.
