Which is responsible for the high thermal energy required to melt ice? (1 point)?

The answer is hydrogen bonding
To know how, first, we have to know that how much the molecules of the substance are moving relative to another one by measuring the temperature. when the temperature gets higher the more molecules are moving. all these moves of the molecules take energy.In our case, we are talking about the pure water H2O the reason that makes the more energy used to get the molecules of water moving and raising the temperature is that the molecules of water are sticking together tightly, As the water molecules are very polar. One side is negative charge O- and the other is a positive charge H+ (It's just like a magnet).So the attraction between the water molecules makes the movement of those molcules harder to move. So to break this attraction, we need more energy to raise the water temperature to change the water phase from solid (ice) to liquid phase.

Answer: A. There will be fewer producers in that area.

Explanation: Answer A is correct because all plants, including grass, is a producer. Since there is an increase in grass eating animals (Antelope), more grass will be consumed, decreasing the amount of grass aka producer.

What makes atoms different than<br> ions?

DENIUS [597]

Answer:the term 'atom' in chemistry represents the basic unit of matter that normally exists in a free state and contains all chemical properties. It is an infinite particle that clearly identifies a chemical element. It consists of a positively charged nucleus and is surrounded by negatively charged electrons.

An ion or charge is an atom or group of atoms that has lost or gained one or more electrons. An ion that has a negative charge, when it gains one or more electrons, is called an anion or negative charge, and an ion that has a positive charge when it loses one or more electrons, is called a cation or positive charge.

What is the concept of galactic recycling?

frozen [14]

Galactic recycling is a natural phenomenon in which the stars expel some gas into the space so that it would mix with the interstellar medium. As a result, this would produce new younger stars. So, basically, the concept done here is the mass and energy conservation. In order to create new species, the energy must come from another source.
