Answers

Answer 1
The volume of an object is how much space can fit inside it. To find the volume of an object, you multiply its length, times its width, times its height. The end result is the volume, which is measured in cubed units (inches sub 3).

Define endothermic reaction.

Answers

Exothermic reaction = the term exothermic process describes a process or reaction that releases energy from the system to its surroundings, usually in the form of heat, but also in a form of light, electricity,

Endothermic reaction = An endothermic process is any process with an increase in the enthalpy H (or internal energy U) of the system. In such a process, a closed system usually absorbs thermal energy from its surroundings, which is heat transfer into the system.

Answer:

An exothermic reaction is a chemical reaction that releases heat energy to the surroundings. This means that the overall energy of the products is lower than the overall energy of the reactants, resulting in a net release of energy in the form of heat. This can be observed as an increase in temperature of the surroundings or an increase in the motion of the reactant particles, as they absorb the energy that is released. Examples of exothermic reactions include combustion, oxidation, and many biochemical reactions.

You have explored some interesting, informative, and amusing examples of models. Now it's time to get creative and make your own model. Here is the requirement checklist for your model:
-Model types can include drawings, diagrams, physical models, virtual simulations, or videos.
-Models must be created by you, not something selected from an online or outside source.
-Submit a presentation, picture, video, or screenshot of your model.
-Submit a one-paragraph summary describing the topic you chose, your model, what it represents, how you made it, and the specific science involved. It is important that you are using science terminology and are accurate.

Now that you know how to create and submit your model, you will need to choose a topic for your model. Choose one of the three topics listed below. Select each topic for an overview.

1- Conservation of Mass-Explore the law of conservation of mass. Model a physical or chemical change, and then demonstrate how mass is conserved before and after the change.
2- Atomic Theory-Explore the atomic theory of atoms. Create a model that represents the motion and intermolecular attractions of particles in solids, liquids, and gases.
3- Thermal Energy-Explore the effects of thermal energy. Model how adding or removing thermal energy affects motion in particles in a pure substance, such as water, or in a chemical reaction.
!!PLEASE CHOOSE ONE OF THE 3 ABOVE!!

All substances taking part in a certain interaction are shown below:
Carbonate = Calcium Oxide + Carbon Dioxide
Calcium Oxide equals: 112 G
Carbon Dioxide equals: 88 G

Which of the following is the correct estimate of the amount of calcium carbonate used in the interaction?

A. Sum of 112 g and 88 g
B. Difference between 112 g and 88 g
C. Twice the sum of 112 g and 88 g
D. Twice the difference between 112 g and 88 g

✿

any help is much appreciated <3
will reward brainliest to the correct answer (•◡•) !

Answers

Answer:The Law of Conservation of Mass simply states that the total amount of mass should not change in a chemical reaction that is isolated (no other objects can enter the reaction). The total mass of the reactants must be equal to the total mass of the products. Thus, the correct estimate of the amount of oxygen used in the interaction is the difference between 133 g and 29 g.

How does changing the Amplitude​ affect the energy of the wave?

Answers

The energy transported by a wave is directly proportional to the square of the amplitude. So whatever change occurs in the amplitude, the square of that effect impacts the energy. This means that a doubling of the amplitude results in a quadrupling of the energy.

Whats the effect of this?
A wave enters a medium where its wave speed is slower.

Answers

Answer:

Wave speed, frequency and wavelength in refraction

Although the wave slows down, its frequency remains the same, due to the fact that its wavelength is shorter. When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases.

Answer:

Waves. Refraction is an effect that occurs when a light wave, incident at an angle away from the normal, passes a boundary from one medium into another in which there is a change in velocity of the light. Light is refracted when it crosses the interface from air into glass in which it moves more slowly.
