Chemical Rxns
This is the name for the starting substances in a chemical reaction, found on the left side of the arrow.
What are reactants?
This particle has a positive charge and is found in the nucleus of an atom.
What is a proton?
This is the transfer of thermal energy from a warmer object to a cooler object.
What is heat?
Nonliving things like sunlight, water, and soil are called this.
What are abiotic factors?
What is Ms. Burke's hometown?
What is Gilroy, CA?
In a chemical equation, the arrow means this.
What is "Produces" or "are converted to"
This particle has a mass of close to 0 atomic mass units
What is an electron?
Temperature measures this property of the particles in a substance.
What is the average kinetic energy of the particles?
Organisms that make their own food through photosynthesis, such as plants, are called this.
What are producers?
What is Ms. Burke's hometown the capital of?
What is the Garlic Capital!
A chemical reaction always forms these, which have different properties than the starting materials.
What are new substances (products)
The number of protons in an atom determines this, which is also the number of electrons in a neutral atom.
What is atomic number?
When you hold an ice cube, it feels cold because this is moving in this direction between the ice and your hand.
What is heat moving from your hand to the ice?
The largest number of individuals of a species that an ecosystem can support over time, based on available food, water, and space, is called this.
What is carrying capacity?
Which St. Anne's teacher did Ms. Burke go to college with?
Ms. McGovern!
Bubbles forming, a color change, light formation, and a temperature change are all signs of a chemical reaction. What is missing?
What is the formation of a precipitate?
An atom has 6 protons and 7 neutrons. What is the mass number?
What is 13
A cup of boiling water has a higher temperature, but a bathtub of warm water has more of this, because it has far more particles.
What is thermal energy?
Resources that are in short supply and keep a population from growing larger are known by this two-word term.
What are limiting factors?
Where did Ms. Burke move here from?
What is San Diego?
This process, used by yeast to make bread rise and by cells to make ethanol, is a chemical reaction that produces carbon dioxide gas.
What is fermentation?
An atom has 9 protons, 10 neutrons, and 10 electrons. Its overall charge is this.
What is -1?
Once a hot metal spoon and the cool soup it’s sitting in reach the same temperature, heat stops flowing between them. Explain why.
What is because they’ve reached thermal equilibrium, so there is no longer a temperature difference to drive the transfer?
A long drought dries up a pond in an ecosystem. Explain how this change in one resource could affect both the producers and the consumers that depend on them.
What is that less water means fewer producers (plants and algae), so consumers that eat them lose food and their populations shrink too?
How many sisters does Ms. Burke have?
What is 2?
