A pneumonic device is a memorization tool that helps you remember things. For example, if you can read music you probably have heard, “Every Good Boy Does Fine” to learn the names of the lines on the treble clef EGBDF. Or maybe your math teacher taught you, “Please Excuse My Dear Aunt Sally,” to help you remember the order of operations. It is now your turn to think of a pneumonic device to remember the water cycle in order. Write your pneumonic device below.

Part A Cut off the top and one side of the milk carton as shown. Use the hole punch (or scissors) to make two holes on opposite sides of the carton. Make sure the holes are low enough for the rubber band to launch the car. Thread the rubber band through the holes, and secure it using paper clips. Stretch the rubber band to launch the toy car away from the box. Pull back the rubber band to different distances, and explain what happens.
Answer:
the harder you pull on the rubber band the further the toy launches.

In an ionic bond, electrons are ___________________. Choose all the apply.
(12pts + Brainlest)
1. gained
2. lost
3. shared
4. neutral
Answer:
Electrons are shared.
Explanation:
In an ionic bond, electrons are gained and lost. So, the correct options are A and B.
What is an ionic bond?An atom can establish bonds with other atoms in two main ways: covalent and ionic. The sharing of electrons between two or more atoms forms a covalent connection. When two or more ions join contact, they can create ionic bonds that are held together by charge differences.
A chemical link in which one atom transfers one or more electrons to another atom is known as an ionic bond. A negatively charged ion, or anion, is created when an atom receives electrons, while a positively charged ion, or cation, is created when an atom loses electrons. The ions' opposing charges draw to one another and create a solid link between them. Usually, a metal and a non-metal atom form ionic connections. Ionic bonds contain electrons.
So, the correct options are A and B.

the figure shows the great ocean conveyor belt. which best describes what this model represents?
A. The model shows how ocean currents change the salinity of water.
B. the model shows how ocean currents move heat energy around earth
C. the model shows how salinity of water affects its density
D. the model shows how the density of water differs between the north Atlantic and other parts of the ocean.
Answer:
d
Explanation:
The ocean conveyor belt shows the movement of the oceanic water and the salinity. The model represents the density of the water in different regions of the world. Thus, option d is correct.
What are ocean conveyor belts?Ocean conveyor belts are the oceanic current movement in their oceans across others and how the water moves across the water bodies across the globe.
The model shows that high salinity water gets heavy and sinks in the ocean of North Atlantic but the water of the Indian and the pacific oceans are less saline and remains at the surface.
Therefore, option D. the water differs in oceans based on density.
