How are the angles and side lengths within triangle related?
Answer:
Explanation:
if the side lengths of a triangle are equal then the angles opposite to those sides are equal . This is a case of an isosceles triangle .
And if all the sides of a triangle are equal then all the angles of a triangle will be equal . This is a case of an equilateral triangle.

This means ____________ objects emit radiant energy.
Radiant energy is emitted from all objects with temperatures greater than ABSOLUTE ZERO. This means ALL objects emit radiant energy.
Radiant Heat and TemperatureRadiant heat is a type of energy that largely depends on the temperature of an object.
This type of energy (radiant energy) is emitted from all objects and can be observed when heat is absorbed on the surface of another material.
Radiant energy can be defined as a type of electromagnetic energy.

What would be the advantage of using a molecular model.
Answer: Can pick it up and hold it, can rotate groups about bonds
and can look for symmetry
Explanation: A molecular model is a plastic model with interchangeable balls. Represents molecules and their processes.
The creation of mathematical models of molecular properties and behavior is molecular modelling, and their graphical depiction is molecular graphics, but these topics are closely linked and each uses techniques from the others.

Explanation:
what type of energy transfer occurs as a coiled spring is released
Answer:
When a spring is coiled up or a rubber band is stretched, mechanical energy is stored in it. When the spring uncoils or the rubber band snaps back, this energy is released. This stored mechanical energy is called potential energy because it has the potential to make things happen.Explanation:

Explain what is a solar eclipse and why they are so rare IN YOUR OWN WORDS
Explain what is a lunar eclipse and why the moon turns red, and why it's more common IN YOUR OWN WORDS
Answer:
This is true: Lunar eclipses happen more often. I think it's just a question of how big the shadows are: There is a lunar eclipse when the Earth blocks the Moon's light from the Sun. 7000 km away from the Moon, the Earth's shadow is about two lunar diameters wide. Much wider than a pancake. The reason that the moon turns red, is due to Earth's atmosphere. It bends red rays of sunlight into our planet's shadow and scatters out blue rays of light.
When the Moon casts a shadow on the Earth, it is called a solar eclipse. The Moon is a lot smaller now, and its shadow is also a lot smaller than it was before. Around 200 or 300 km across is how big the Moon's shadow is when it's far from the Earth.
Fun Facts:
- The 21st century has 224 solar eclipses and 230 lunar eclipses (all varieties of each combined)
[WILL MARK BRAINLIEST!!] Describe the relationship between molecular structure and the strength of electrostatic
forces between molecules. How does this impact boiling and melting points?
Answer:
increase the bonding strength between two or more molecules
hope this help
Explanation:
Boiling points and melting points
The overarching principle involved is simple: the stronger the noncovalent interactions between molecules, the more energy that is required, in the form of heat, to break them apart. Higher melting and boiling points signify stronger noncovalent intermolecular forces.

The electron configuration of element Y ends in s?p4. What is
the symbol for the ion most commonly formed by this element?
a y2+
b y2-
с ү6+
d Y
This problem is providing us with the end of the electron configuration an element as s²p⁴ and asks for the most commonly formed ion. At the end, the answer is b Y²⁻.
Electron configurationIn chemistry, when analyzing electron configurations, one must first take into account how the energy levels must be filled with electrons.
Now, note the problem states that the electron configuration ends by s²p⁴, which means it is closer to complete the octet so it needs two electrons in order to do so, as it behaves as a nonmetal.
Therefore, the most commonly ion formed by this element is Y²⁻, because of the fact that it needs two electrons to complete the octet and thus become chemically stable and likely to bond with a metal.

does this image show a physical or chemical change?
Answer:
Physical
Explanation:
When a substance changes from liquid to gas it's a physical change. There is no chemical reaction between the rubbing alcohol or anything else that would change it's chemical composition.
According to the Law of Conservation of Matter, what happens to atoms of gas in a balloon when it is placed in the freezer?
the number of atoms stays the same and the energy stays the same, keeping the volume the same
the number of atoms stays the same as the atoms lose energy to the colder freezer, slow down, get closer together, shrinking the volume
the number of atoms increases, causing an increase in energy and an increase in volume
the number of atoms decreases, which takes up less space and decreases the volume
Answer:
the number of atoms stays the same as the atoms lose energy to the colder freezer, slow down, get closer together, shrinking the volume
Explanation:
When a liquid is cooled, the average energy of the molecules decreases. At some point, the amount of heat removed is great enough that the attractive forces between molecules draw the molecules close together, and the liquid freezes to a solid.
