Answer:
This is where google becomes your best friend but I got you
Explanation:
1. A theory used to predict the rates of chemical reactions, particularly for gases. The collision theory is based on the assumption that for a reaction to occur it is necessary for the reacting species (atoms or molecules) to come together or collide with one another.
2. Collision theory says that chemical reactions occur by the collisions between atoms and molecules, so the more collisions the faster the rate of the chemical reactions.
3. The speed at which a chemical reaction proceeds. It is often expressed in terms of either the concentration (amount per unit volume) of a product that is formed in a unit of time or the concentration of a reactant that is consumed in a unit of time.
4. There are four main factors that can affect the reaction rate of a chemical reaction:
Reactant concentration. Increasing the concentration of one or more reactants will often increase the rate of reaction. ...
Physical state of the reactants and surface area. ...
Temperature. ...
Presence of a catalyst.
Answer:
1. a theory that says a chemical reaction takes place when particles of the reactants collide with sufficient energy to initiate the reaction
2. Increasing the concentration of the reactants, the faster the particles will collide so the reaction rate will be faster
3. a measure of how fast a reaction takes place
4. Temperature, presence of a catalyst, reactant concentration, surface area

Carbon atoms in diamond are arranged in connecting cubes. Carbon atoms in charcoal are arranged more randomly. Using the names of the structures a solid can have, describe the differences between these forms of carbon.
Answer: Charcoal is the charred product from pyrolyzing wood. Charcoal is a porous material that can burn or adsorb pollutants, carbon atoms in diamond are arranged in the same way something in the solid state of matter would be arranged- like building blocks. if the carbon atoms in charcoal are arranged more randomly but still close
together, thats similar to the way a liquid would look!
Answer:
The carbon atoms in diamond are arranged like building blocks in the solid state of matter, whereas the carbon atoms in charcoal are arranged more randomly but still close together.
What does it mean for waves to be absorbed? Make sure to include energy in your explanation.
Answer:
The energy of a wave is transferred to the material it encounters. Ex.) When the ocean waves meet the shoreline, most of their energy is absorbed by the shore.
Explanation:
Ex.) When the ocean waves meet the shoreline, most of their energy is absorbed by the shore.
Wave absorption takes place when a wave transfers its energy to the atoms and molecules of the medium it comes in contact with.
What does it mean for a wave to be absorbed ?When a wave is absorbed, matter absorbs energy from the wave, lowering its amplitude. When a sound wave strikes foam padding, for example, the energy passes through the material and is sometimes converted into heat or other forms of energy.
The energy of a wave is transferred to the particles in the surface when it is absorbed by a surface. This usually causes the particles' internal energy to increase.
Some wavelengths or colors of light are absorbed when white light shines on an opaque object.
Thus, Wave absorption takes place when a wave transfers its energy to the atoms and molecules of the medium it comes in contact with.

How is radiant energy transformed into chemical energy?
Answer:
Photosynthesis is the transformation of radiant energy to chemical energy. Plants take in water, carbon dioxide, and sunlight and turn them into glucose and oxygen. Called photosynthesis, one of the results of this process is that carbon dioxide is removed from the air.

What is the funtion of the lungs in the respiratory system? (Use complete sentences.)
Answer:
The lungs' main role is to bring in air from the atmosphere and pass oxygen into the bloodstream. From there, it circulates to the rest of the body. Help is required from structures outside of the lungs in order to breath
Explanation:
Explanation: The lungs are the most important part of the respiratory system. They give air to serve the whole entire body. Lungs are one of the most vital organs of the body, since they help us breathe, and if we did not breathe, we would die.

Answer:
number (12 is c) (13 is 5) (14 is 5)
Explanation:
Answer:
12:B 13: 5 m/s 14: 5 m/s
Explanation:
12: this is a position vs time graph, and that worded description matches the graph because the slope of a p vs t graph is the velocity
13: again, the slope of a position vs time graph is the velocity. 10m/2s = 5 meters a second or m/s
14: same thing. the object travels 30 m in 6 s so 30/6=5 m/s
