The planets orbit the sun because they are attracted by the sun's
A
heat
B
Light
С
gravity.
D
friction
Answer:
Gravity of sun
Explanation:
The Gravity force of the sun holds the planets and other planetary body in their certain orbits. The Earth and other planets circles the Sun due to the gravitational force of the Sun, much as the Moon orbits the Earth due to the gravitational pull of the planet Earth. Moon revolve around earth and same earth and other planet revolve around sun.
Take a look at the following chemical equation. Complete the following: balance the equation, explain how the conversation of matter supports your answer, and identify the type of reaction.
Answer:
2 NaOH + H₂SO₄ ⇒ Na₂SO₄ + H₂O
We can see that Lavoisier's law of conservation of matter is obeyed because we have the same type and amount of elements on both sides of the equation.
Neutralization reaction.
Explanation:
Let's consider the following unbalanced equation. This is a neutralization reaction.
NaOH + H₂SO₄ ⇒ Na₂SO₄ + H₂O
First, we will balance Na atoms by multiplying NaOH by 2.
2 NaOH + H₂SO₄ ⇒ Na₂SO₄ + H₂O
Then, we get the balanced equation by multiplying H₂O by 2.
2 NaOH + H₂SO₄ ⇒ Na₂SO₄ + H₂O
We can see that Lavoisier's law of conservation of matter is obeyed because we have the same type and amount of elements on both sides of the equation.
Directions: Complete the paragraph by writing the equivalent word or group of words in each
diagram presented. Write your complete paragraph/answer on your answer sheet.
Answer:
1) sunlight
2) radiation
3) radiant Energy
4) heat
5) temperature
Explanation:
1) Solar energy is derived from the sunlight.
2) Now, solar energy gets to the Earth's atmosphere by electromagnetic radiation which warms the Earth's surface.
3) Sunlight is a form of radiant energy because the light from the sun is transmitted by radiation to the earth.
4) When sunlight reaches the earth it is converted to heat energy.
5) Due to the heat from the sun, it will increase the Temperature of objects.

This is the original color of the Statue of Liberty gifted to the United States by
France. It's very different from the way it looks today. Describe why it has
changed and possible causes.?
Answer:
The Statue of Liberty represents Libertas, the Roman Goddess of Liberty. She is holding a torch and a tablet with the date of the US Declaration of Independence. She is dressed in a robe, wears a crown, and has a broken chain at her feet. The Statue of Liberty was a gift from France to the United States. It was designed by the sculptor Frederic Auguste Bartholdi and built by Gustave Eiffel in 1886. The US designed and paid for the granite and concrete foundation .Over the next three decades, the statue slowly began to change color. Currently, the Statue of Liberty is green in color. How did this happen? The air and water reacted with the copper metal and resulted in oxidation. This oxidation created a layer of patina, a copper carbonate. This does not harm the statue and actually helps to protect the copper sheets below.

Answer:
during the Revolutionary War, France became a close friend of Americans seeking freedom from Great Britain. To honor its friendship with America, France gave the U.S. a special gift: sculptor Frederic-Auguste Bartholdi's beautiful statue called Liberty Enlightening the World.
The Statue of Liberty arrived in New York Harbor on June 19, 1885. It came in 350 pieces packed into 214 crates. The statue was assembled on a pedestal base built by the United States. The 151-foot tall statue has become a worldwide symbol of freedom and democracy.
The Statue of Liberty's home is Bedloe's Island (renamed Liberty Island in 1956). From 1892 to 1943, “Lady Liberty" greeted over 12 million immigrants as they arrived on boats at the nearby Ellis Island Immigration Station.

Dry air is 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide so varying amounts of water vapor- depending on humidity. Some gases however strongly absorb infrared radiation and trap it in the atmosphere and can therefore result in elevated global temperatures. Therefore they are termed greenhouse gases. Which greenhouse gas have we observed a marked increase in atmospheric concentrations in the last 100 years?
A. methane (CH4)
B. carbon monoxide
C. carbon dioxide
D.ozone (03)
E. oxygen
F. nitrogen
G.water vapor (H20)
Answer:
C. Carbon dioxide
Explanation:
Carbon dioxide is one of the end-product of combustion reactions involving many fuels today.
With the rapid increase in urbanization and technological development, man demand for energy increased tremendously. The discovery of fossil fuels paved the way for the astronomical increase in the concentration of carbon dioxide in the atmosphere. The burning of fossil fuels like coal and oil invovles the process where the carbon atoms present in these fuels combine with oxygen in the air to make CO2. This has resulted in an increase in the concentration of atmospheric carbon dioxide (CO2).
The burning fossil fuels for electricity, industry, heat, and transportation are the major sources of the emossion of carbon dioxide.
Also, the cutting down of trees for paper production, building construction and for the establishment of settlements also increase the concentration of carbon dioxide in the atmosphere. Trees are help remove carbon dioxide from the atmosphere through the process of photosynthesis. However, when these trees are cut down, carbon dioxide accumulates in the atmosphere.

As NH4Cl dissolves in water, and cools the solution,
a. delta H is negative, and delta S is negative
b. delta H is positive, and delta S is negative
c. delta H is negative, and delta S is positive
d. delta H is positive, and delta S is positive
Answer:
d. delta H is positive, and delta S is positive
Explanation:
The process of dissolution of NH4Cl is:
NH4Cl(s) → NH4+(aq) + Cl-(aq)
As the solution is cooled, the process is absorbing energy, that means ΔH > 0. (ΔH < 0 when the heat is released).
As there are produced 2 ions from 1 solid molecule, the disorder is increasing and ΔS > 0
The right answer is:
d. delta H is positive, and delta S is positivecalculate the relative molecular mass of Ma(HCO3)2
Answer:I believe you mean Mg(HCO3)2. Since I have never heard of the element MA. but if you are calculating using mg(HCO3)2 your molar mass/ molecular mass will be 146.3387

What is the study of matter and energy and how do they interact?
Physics is the scientific study of matter and energy and how they interact with each other. This energy can take the form of motion, light, electricity, radiation, gravity - just about anything, honestly. Physics deals with matter on scales ranging from sub-atomic particles (i.e. the particles that make up the atom and the particles that make up those particles) to stars and even entire galaxies.
What are energy and its relation to matter?
The mass of these three particles is less than the mass of a neutron, so they each get some energy as well. So energy and matter are really the same things. Completely interchangeable. And finally, Although energy and mass are related through special relativity, mass and space are related through general relativity.
