Flashcards in Water and Chemical Reactions Deck (22):
The oxygen side of water has this kind of charge.
Because water has an equal number of protons and electrons, it is described as this.
The hydrogen side of water is slightly positive because of these.
Protons in the hydrogen nuclei are positive
This is the attraction of water molecules to water molecules.
In water, the electron cloud swarming mostly around oxygen has this charge.
Cohesion causes this.
In water, this has a greater force of attraction of electrons than the hydrogen nuclei.
The oxygen nucleus, because it has 8 protons attracting the electron cloud while the hydrogen each only have 1 proton attracting electrons.
Adhesion is the attraction of water to . . .
molecules OTHER than water.
This is what happens to bonds during chemical reactions.
Bonds are broken &/or formed.
Reactants get turned into these during chemical reactions.
This is what happens to atoms during chemical reactions.
They are rearranged.
This is the name for those substances that BEGIN a chemical reaction.
This is the name of the substances that are generated in a chemical reaction.
This is another name for a chemical change.
During chemical reactions, energy levels can change but the amount of matter . . .
These reactions build products of HIGHER potential energy.
Stored energy is called this.
This is the term used to describe the energy needed to start a chemical reaction.
This is energy that is in use.
These reactions release more energy than they absorb.
This type of reaction ALWAYS requires activation energy.
