Answer/Explanation:
In a chemical reaction, the atoms and molecules produced by the reaction are called products. ... No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
This question involves the concepts of a chemical reaction, conservation of mass, chemical bonds.
During a chemical reaction, the phenomenon that is most likely to occur from the given phenomena is "Mass is conserved".
Whenever a chemical reaction occurs old bonds between the elements are broken and new bonds are formed amongst different elements. Hence, the properties of the original substances are changed due to the formation of new bonds, and new molecules as a result.
Original molecules or substances are lost due to formation of the new ones.
No new atoms are created or destroyed in a chemical reaction. The atoms just rearrange themselves to form new molecules or substances only.
Since no atoms are created or destroyed during a chemical reaction. Hence the law of conservation of mass is applicable to a chemical reaction. This means the mass is conserved during a chemical reaction.

Answers
Seagrasses are a vital part of the marine ecosystem..
Seagrasses are submerged flowering plants found in shallow marine waters, such as bays and lagoons and along the continental shelf in the Gulf of Mexico. A vital part of the marine ecosystem due to their productivity level, seagrasses provide food, habitat, and nursery areas for numerous vertebrate and invertebrate species. The vast biodiversity and sensitivity to changes in water quality inherent in seagrass communities makes seagrasses an important species to help determine the overall health of coastal ecosystems. Seagrasses perform numerous functions:
Stabilizing the sea bottom
Providing food and habitat for other marine organisms
Maintaining water quality
Supporting local economies

There is a thing called a continental drift. It started about 200 million years ago. At first the continents were all attached, this super continent was called pangaea. Continental drift occurs because of the shift of the tectonic plates within the earth's outer shell. The heat from within the earth triggers movement to occur. This a very slow process though. It took 200 million years for the continents to get where the are now and would probably take another 200 to collide.

What fraction of the Moon model was always lit up by the light in your model?
Answers
Answer:10
Explanation:
In the context of the Moon model, the fraction of the Moon that was always lit up by the light is half, or 1/2.
The explanation for this is that the Moon model discussed previously most likely depicts the Moon's phases as seen from Earth. The phases of the moon are caused by distinct areas of the lit side of the moon that are visible from Earth at various times during its orbit.
The Sun always illuminates half of the Moon's surface, leaving the other side in darkness. From Earth, we can only see the bright portion; the unlit portion is invisible. Different phases result from variations in the visible fraction of the lighted half of the Moon as it revolves around the Earth.
Therefore, the fraction of the Moon that was always lit up by the light is half, or 1/2.

The meteor's potential energy if it has a mass of 10kg at an altitude of 400 m will be 39200 J
What is potential energy ?Potential Energy that depend upon the relative position of various parts of system . It is an energy possessed by an object by virtue of its position or configuration.
mass(m) = 10kg
g (acceleration due to gravity) = 9.8m/s^2
altitude(height (h)) = 400m
Meteor's Potential energy = m * g * h
= 10 * 9.8 * 400 = 39200 J

4. The Himalayan Mountains tower as high as 8,854 m above sea level. The rate of plate motion is about 10 cm per year. Use the diagram to explain how the Himalayas formed. Predict how they might look in 10 million years.
Answers
Answer:
Forty million years ago, the continent of India, which was being carried northward by the Indo-Australian plate, collided with Asia forming the Himalayan mountain range (fold mountains). Since the initial encounter, the subcontinent of India has moved 2,000 kilometers farther north at a rate of 5 centimeters a year, sliding beneath Asia as it moves. In 10 million years India will plow into Tibet a further 180km. This is about the width of Nepal.

Students have a small steel ball and a large steel ball, and they have a short ramp and a tall ramp.
The students want to find out if a ball's size affects how far it can roll. They also want to find out if the height of the ramp affects how far the ball can roll.
They do the following experiment: (second image)
The students finish conducting their tests and conclude that using a taller ramp and a larger ball will make the ball roll further. Is their conclusion based on a reliable experiment?
A.Yes, because they used the same color balls.
B.No. They did not do an additional test to compare the results using the short ramp.
C.No. The small ball should have been pushed with more force.
D.Yes, because they changed the height of the ramp.

Explanation:the smaller ball will reach before because it's density is low because of its small size and the small ball will reach before because it's lighter
How will the total energy change as the car moves from point A to B to C? Assume that none of the energy is lost as friction or heat energy.
A The total energy will increase as the kinetic changes to potential and back again.
B Kinetic energy will change into potential energy and back again, but the total energy will stay the same.
C The total energy will decrease because the potential energy will change into kinetic energy.

Answers
Answer:
atoms that no longer have a neutral charge are called ions!
Explanation:
when atoms gain or lose electrons, they become either negatively charged or positively charged in the process. losing electrons means the atom becomes more positive, therefore positively charged. gaining electrons means the atom becomes more negative, so negatively charged. atoms that go through this process of gaining or losing electrons are called ions.
