Modeling Conservation of Mass
What is the Law of Conservation of Mass?
This state of matter has particles packed tightly that only vibrate in place.
What is a solid?
This process happens when liquid water turns into water vapor due to the Sun's energy.
What is evaporation?
This state of matter contains atoms that are moving very quickly and are sometimes colliding at high speeds.
What is a gas?
Energy of motion.
What is Kinetic Energy?
In the expression 3H2O, this number tells you how many water molecules are present.
What is 3, the coefficient?
When thermal energy is added to a liquid, this process occurs.
What is boiling/evaporation?
This force pulls precipitation toward Earth and causes water to flow from high to low elevation.
What is Gravity?
This state of matter is found when thermal energy is removed from a gaseous substance.
What is a liquid?
The smallest particle of an element; made of protons, neutrons, and electrons.
What is an atom?
These are the types of compounds created when electrons are transferred (donated) between atoms.
What is an Ionic Compound?
At this temperature in ºC, water freezes or melts.
Clouds are made up of water in this state of matter that has attached to dust particles in the air.
What is liquid?
Water vapor cools in the atmosphere, forming clouds. This change in state is caused by thermal energy being _________.
What is removed (or lost)?
To move rhythmically and steadily; oscillate.
What is vibrate?
In order to calculate the mass of the reactants and products of a chemical equation, you need to use this value from the periodic table.
What is the atomic mass/weight?
On a phase change graph, the flat sections of the graphs represent this.
What is a phase change?
This process is responsible for moving water from plants into the atmosphere and plays a major role in maintaining humidity levels in forests.
What is transpiration?
A beaker contains water mixed with sand. After several days, the water is gone but the sand remains. This shows that during evaporation, only this part of the mixture changes state.
What is water?
A measure of how much matter is present in a substance.
What is inert?
What are the coefficients needed to balance the following equation:
____ N2 + ____ H2 ---> ____ NH3
What are 1, 3, 2?
Water is unique because when it freezes, its volume increases due to this structure.
What is hexagonal lattice structure?
This process acts as a natural filtration system, removing impurities as water moves through soil and rock layers.
What is percolation?
What are the coefficients needed to balance the following equation:
____ C2H4 + ____ O2 ----> ____ CO2 + ____ H2O
What is 1, 3, 2, 2?
Not chemically reactive; used to describe a substance.
What is inert?
