Answer 1

Answer:

Sorry i cant see this question

Explanation:

Sorry

Answer 2
It’s 2 1 2 as oxygen on RHS will have 2 oxygens which makes hydrogen 4 and since hydrogen is already 2 to make it 4, we just have to multiply by 2.

What does it mean for waves to be absorbed? Make sure to include energy in your explanation.

Answers

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.

1. What is collision theory?


2. How does collision theory relate to factors that affect reaction rate?



3. Define reaction rate.


4. List factors that influence the rate of a chemical reaction.


5. Choose one of the factors you listed in your answer to question 2, and explain how it affects reaction rate.

Answers

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
