Explanation:

Answer 2

This question is incomplete because it does not include the image of the model. But it can be answered based on my previous knowledge.

A CH4 atom has 4 hydrogen atoms and 1 carbon atom.

Methane is a chemical compound classified as a hydrocarbon whose chemical formula is CH4. This compound is found in nature in the form of a gas and has no odor or color. It originates as a result of the decomposition of plants.

According to its chemical formula CH4, it can be inferred that methane is made up of one carbon atom and four hydrogen atoms.

Substance 2 has a stronger molecular attraction.

What are solids?

Solid is one of the four fundamental states of matter. The molecules in a solid are closely packed together and contain the least amount of kinetic energy. A solid is characterized by structural rigidity and resistance to a force applied to the surface.

Both solids are supplied with an equal amount of energy. Out of both substances, substance 2 has a stronger molecular attraction due to which it can not easily change into a liquid while substance 1 has a lesser molecular attraction so supplying of few amounts of heat will change substance 1 into a liquid state.

Hence, Substance 2 has a stronger molecular attraction.

What do you think causes a lunar eclipse? (Use your knowledge of solar eclipses and feel free to run the Gizmo to help you.)

Answers

Moon reflects the light frim the sun, thats why we are able to see it and it shines in the night. But, we know that Earth revolves around Sun and Moon revolves around Earth. During this revolution, Earth and Moon comes in a position when Earth is in the middle of the Moon and Sun. So, it blocks the light of Sun frim reaching Moon. Hence, we see no reflection and it causes Lunar eclipse.

Answer:

A total lunar eclipse occurs when the moon and the sun are on exact opposite sides of Earth. Although the moon is in Earth's shadow, some sunlight reaches the moon. The sunlight passes through Earth's atmosphere, which causes Earth's atmosphere to filter out most of the blue light.

Explanation:

Chemical bonds are a force that hold together atoms in a substance to make compounds more stable.

Chemical bonds include two kinds: Ionic and Covalent.

Ionic in which electrons are lost or gained where attraction is between a Metal and Nonmetal.

Covalent in which electrons are shared where attraction is between a nonmetal and nonmetal.

Need help. Is this correct

Answers

Answer:

Yes, that is correct!

Explanation:

Answer:

Yes

Explanation:

A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are simultaneously attracted by the two atomic nuclei. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions.

how does eating contribute to the flow of energy in a ecosystem

Answers

Answer:

Eating contributes to the flow of an ecosystem because in a food web/chain, there is always a consumer. Starting from the very bottom of the food web/chain, all organisms eat to pass on the energy to the next cosumer. For example, a grasshopper eats some grass. That grass is made into energy. Then, a possum eats that grasshopper, the energy from the grasshopper converting to the energy of the possum. Then a giant snake comes along and eats the possum. The energy keeps flowing up and up the food chain as animals consume(and be consumed).

The food chain begins with producers, organisms such as green plants, that can make their own food. Through photosynthesis, producers convert solar energy to chemical energy, energy in the chemical bonds of the food. Plants are eaten by consumers, which are organisms that cannot make their own food.

-Carbon bonds in food are broken, which releases energy.
-Weathering breaks down rocks into chemicals like sulfur and nitrogen. -Consumers make food using light energy from the sun.
-Energy is absorbed as heat when plants make food

Is it possible for two different compounds to be made from the exact same two elements? Why or why not? With a limited number of elements (less than 120 are known), does this mean we also have a small number of compounds or do we have a large number of compounds in this world?
PLEASE HELP ASAP
Thank you!!

Answers

Answer:

Yes. The two elements can combine to form different compounds.

Explanation:

Two elements can combine at different ratios.

Consider CO and CO₂. Both are made from carbon and oxygen. However, C and O combine at a 1:1 ratio in CO but at a 1:2 ratio in CO₂. CO is a fuel; it burns in the air. CO₂ does not burn in the air; it is used to put out fires and is found in extinguishers. CO and CO₂ are two distinct compounds.

There are many ways for the elements to combine with each other. As a result, the first twenty elements on the periodic table alone can produce a large number of compounds.

Answers

Answer:

No of protons = 15

Explanation:

Given that,

Atomic number = 15

Mass number = 31

We need to find the no of protons in the atom.

We know that,

No of protons = Atomic no of the atom

No of protons = 15

Hence, there are 15 protons in the atoms.

Mars

What is the orbit of the Mars?
Is the Sun at the center of the Mars’s orbit?
Describe the motion of Mars throughout its orbit? Does it move at constant speed?

Answers

Answer:

Mars has an orbit with a semimajor axis of 1.524 astronomical units (228 million km), and an eccentricity of 0.0934 The planet orbits the Sun in 687 days and travels 9.55 AU in doing so making the average orbital speed 24 km/s.

The eccentricity is greater than that of every other planet except Mercury, and this causes a large difference between the aphelion and perihelion distances—they are 1.6660 and 1.3814 AU

Explanation:

Answer: i hope this helps :)

-- 687 days

-- After years of analysis, Kepler discovered that Mars's orbit was likely to be an ellipse, with the Sun at one of the ellipse's focal points. This, in turn, led to Kepler's discovery that all planets orbit the Sun in elliptical orbits, with the Sun at one of the two focal points.

-- From our point of view as we race around the Sun, Mars is falling behind; consequently, we see Mars moving in a retrograde direction from night to night across the sky. Since the Earth always moves around the Sun faster than Mars, you might imagine that Mars's motion will always be retrograde.

-- Basically, that planets do not move with constant speed along their orbits. Rather, their speed varies so that the line joining the centers of the Sun and the planet sweeps out equal parts of an area in equal times. The point of nearest approach of the planet to the Sun is termed perihelion

1. In which area are you most likely to find plants that can tolerate water that has a constantly
changing salt content?
A. a freshwater stream
B. an estuary
C. a a pond
D. a coral reef

Answers

Answer:

I would think B, an estuary. But I'm not sure.

Explanation:

The area where the plants should be find in which the water should be tolerated should be estuary.

What is an estuary?

An estuary refer to the enclosed body with respect to the brackish water  that have one or more rivers or streams that should be flow into it. Also, there should be free connection to the open sea. It should be considered as the transition zone that lies between the river environment and maritime environment

Therefore, we can conclude that the option b is correct.
