What are 5 properties of water
100
the left side
which side of the chart is more acidic
100
oxidation and reduction
What is the two reactions the make up the redox reaction
100
protons neutrons and electrons
What makes up the atom
100
covalent,ionic,hydrogen and polar covalent
What are the different types of bonds
200
cohesion is when water sticks to itself very easily
What is cohesion
200
they have a bitter taste
What type of taste does basic foods have
200
oxidation is when a compound loses hydrogens
What is oxidation
200
positive and in the nucleus
What charge does a proton have and where is it located in the atom
200
a chemical bond that involves the sharing of electron pairs between atoms
What is a covalent bond
300
Adhesion means that water also sticks very well to other things, which is why it spreads out in a thin film on certain surfaces, like glass
What is adhesion
300
number 7 on the scale is neutral
Which part of the scale is neutral
300
reduction is when a compound gains hydrogens
What is reduction
300
negative and outside the nucleus
What charge does a electron and where is it located in a atom
300
he complete transfer of valence electron(s) between atoms
What is an ionic bond
400
This means that the molecules on the surface of the water are not surrounded by similar molecules on all sides, so they're being pulled only by cohesion from other molecules deep inside
What is surface tension
400
on the left side the lower the number the stronger the acid
on the left side which is stronger
400
hydronium
H2O+H2=H3O is what
400
neutral and in the nucleus
what charge does a neutron have and where is it located in the atom
400
a weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other
What is a hydrogen bond
500
the two hydrogen atoms and one oxygen atom within water molecules (H2O) form polar covalent bonds
What is polarity
500
on the right side the bigger the number the more basic and bitter the taste is
on the right side which is stronger
500
enzymes-proteins with specific function and catalysts-reduce activation energy and speed up the reaction
what are enzymes and catalysts
500
each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei
What is an isotope
500
The greater the electronegativity difference, the more ionic the bond is. Bonds that are partly ionic are called polar covalent bonds
