Acids, Bases, & pH (Day 7)
There are different properties of acids. One of them is
What is - contains hydrogen (H+) ions, pH 0-6.9, sour taste, turns litmus paper blue --> red ?
A physical change is
What is - a change that does not change the chemical composition of the substance (ex: ripping a piece of paper) ?
The common 3 stages of matter are
What is - solid, liquid, and gas ?
Boyle's Law states
What is - pressure and volume have an indirect relationship ?
There are different properties of bases. One of them is
What is - contains hydroxide (OH-) ions, ph 7.1-14, bitter taste, slippery feel, turns litmus paper red --> blue ?
A chemical change is
What is - a change that changes the chemical composition of the substance so a brand new substance is formed (ex: burning a piece of paper, baking a cake) ?
There are 2 other extreme states of matter, which are
What is - plasma and the Bose-Einstein condensate ?
Charles's Law states
What is - temperature and volume have a direct relationship ?
Some common household acids are
What is - citrus fruits (ex: lemons, limes, oranges), vinegar, battery acid ?
Rusting is an example of this type of change
The phase change from a solid to a gas is ______, and from a gas to a solid is _______
What is - sublimation, deposition ?
Gay Lussac's Law states
What is - temperature and pressure have a direct relationship ?
What is - bleach, soap, ammonia, lye ?
There are clues that can help tell you that a chemical change has happened to a substance. An example of one of these clues is
What is - heat being given off, gas bubbles forming, color change, smell, precipitate (substance at the bottom of container), cannot easily be turned back to original state ?
What is - increases, remains constant ?
The volume of a gas will ______ as the pressure increases.
What is - decrease ?
The chemical reaction when you mix an acid and a base is called this. Water, gas, and salt are produced during this type of reaction.
What is - neutralization reaction ?
What is - physical, chemical ?
There are 3 parts to the Kinetic Theory, they are
What is - (1) All matter is made of small particles, (2) Particles are in constant random motion, (3) The particles are colliding (hitting) each other and the walls of their container ?
The gas law that explains why a hot air balloon rises when filled with hot air is
What is - Charles's Law ?
