Spiral galaxies

Explanation:

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.

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

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.

.ANSWER:Copper is a ductile metal

EXPLAIN :This means that it can easily be shaped into pipes and drawn into wires. Copper pipes are lightweight because they can have thin walls. They don't corrode and they can be bent to fit around corners.

Copper is a ductile metal due to ductility.This means that it can easily be shaped into pipes and drawn into wires. Copper pipes are lightweight because they can have thin walls.

Ductility is a mechanical property commonly described as a material's amenability to drawing (e.g. into wire).In materials science, ductility is defined by the degree to which a material can sustain plastic deformation under tensile stress before failure. Ductility is an important consideration in engineering and manufacturing. It defines a material's suitability for certain manufacturing operations (such as cold working) and its capacity to absorb mechanical overload.

Some metals that are generally described as ductile include gold and copper, while platinum is the most ductile of all metals in pure form.However, not all metals experience ductile failure as some can be characterized with brittle failure like cast iron. Polymers generally can be viewed as ductile materials as they typically allow for plastic deformation.

Answer:

Radiant; electromagnetic; kinetic energy.

Explanation:

Energy can be defined as the ability (capacity) to do work. The various forms of energy are solar energy, electrical energy, chemical energy, thermal energy, wind energy, nuclear energy etc.

The two (2) main types of energy are;

a. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.

b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.

Light and radio are examples of the radiant or electromagnetic energy form, which is kinetic energy because it is always moving.

Kinetic energy can be defined as an energy possessed by an object or body due to its motion.

Mathematically, kinetic energy is given by the formula;

[tex] K.E = \frac{1}{2}MV^{2}[/tex]

Where;

K.E represents kinetic energy measured in Joules.

M represents mass measured in kilograms.

V represents velocity measured in metres per seconds square.

Answer:

During the initial cell operation, each reaction is thermodynamically favorable, but the larger operating potential of the lithium-iodine cell indicates that its cell reaction is more thermodynamically favorable.  ( B )

During the initial cell operation, the oxidation of iodine is  thermodynamically favorable but the oxidation of mercury is not. ( C )

Explanation:

The major Differences between The Zinc mercury cell and Lithium-iodine cell are :

During the initial cell operation, each reaction is thermodynamically favorable, but the larger operating potential of the lithium-iodine cell indicates that its cell reaction is more thermodynamically favorable.   and

During the initial cell operation, the oxidation of iodine is thermodynamically favorable but the oxidation of mercury is not.

Given the relationship below,

Δ G = -nFE

E = emf of cell ,  G = free energy.

This relationship shows that if E is positive the reaction will be thermodynamically favorable also if E is large it will increase the negativity of free energy  also From the question we can see that with the reduction of mercury the value of E is more positive and this shows that Mercury is thermodynamically unfavorable

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.
