The statue of liberty is made of copper and over time has been oxidized by water and air, making it green instead of silver. What kind of weathering is this?”
erosion
physical weathering
deposition
chemical weathering
Answers
Answer:
D. Chemical weathering
Explanation:
Chemical weathering is the erosion or disintegration of rocks, building materials, etc., that are caused by chemical reactions. The green patina on the Statue of Liberty is a direct result of chemical weathering to copper.
Chemical weathering depicts the reaction of Copper of the statue.
What is Chemical weathering?This is defined as the disintegration of a substance through chemical reactions.
The statue was said to be made of Copper which was oxidized by water and air thereby changing its color from silver to green is an example of chemical weathering.

Answer:
The air gap is too narrow to allow the air to circulate easily. This therefore reduces the rate of heat transfer by convection. The trapped air reduces the rate of heat loss through the window by conduction and convection. The room in the house therefore stays warmer for longer reducing heating costs

Explanation:
Cristalización y disolución de cloruro de sodio: equilibrio físico dinámico
Conversión de oxígeno gaseoso en ozono - equilibrio químico
Condensación y evaporación de un líquido - equilibrio físico dinámico
Reacción entre H2 y 12 para producir Hl - equilibrio químico
Una solución saturada de azúcar - equilibrio físico dinámico
El equilibrio alcanzado en los procesos físicos se llama procesos físicos. El equilibrio físico se llama. Ejemplos de tales procesos físicos incluyen; condensación y evaporación, cristalización y disolución, etc.
Un equilibrio dinámico ocurre en un sistema químico cuando la reacción directa y la reacción inversa se desarrollan a la misma velocidad.
1. Suppose that the volume of a gas in a cylinder is 1.35 L at a pressure of 2.15 atm. What is the new volume if the
pressure is decreased to 1.86 atm? (Temperature and amount of gas remain constant.)
Answers
The volume of a gas in a cylinder is 1.35 L at a pressure of 2.15 atm, if the pressure is decreased to 1.86 atm then the new volume is 1.56 L.
What is pressure?Pressure is defined as the force applied perpendicular to the surface of an object per unit area over which the force is distributed.
It can also be defined as the force exerted on a given area.
Pressure can be expressed as
Pressure = force / area
There are mainly four types of pressure
Absolute pressureGauge pressureDifferential pressureVacuum pressureUsing the formula P1V1 = P2V2
As given P1 = 2.15, V1 = 1.35 and P2 = 1.86
So, V2 = P1V1 / P2
= 2.15 x 1.35 / 1.86
= 1.56 L
Thus, the volume of a gas in a cylinder is 1.35 L at a pressure of 2.15 atm, if the pressure is decreased to 1.86 atm then the new volume is 1.56 L.

write any three reason for the profuse use of plastic . although it is harmful .
Answers
(2)The "use" of plastics is not harmful per se, and plastics themselves are innocuous (one reason that they fail to readily biodegrade is that they do not interact with biological systems). But poor manangement of waste plastic can lead to problems.
(3)Failing to recycle and reuse synthetic polymers can lead to those items not landfilled (which is a separate issue - ultimately we would run out of landfill sites) items ending up in the sea, rivers or in the general environment where they can be hazardous to wildlife, and look unsightly.
But that is down to poor management, and societal attitudes, not down to the fact that the items are made of plastics.
(4)If we failed to manage sewage and simply discharged that into the streets or into rivers that would be a major problem too. But that doesn't mean we should "ban sewage" - just manage it in an effective way.

Answer:
2H2S + 3O2 --> 2H2O + 2SO2
2 mol H2S/8 mol H2O = 0.25 mol
Explanation:
Reactants: H is 2; S is 1; O is 2
Products: H is 2; S is 1; O is 3
There are 3 oxygens so add a 2 to the H2O e and 3 to the reactants side.
H2S + 3O2 → 2H2O + SO2
Reactant side: H is 2; S is 1; O is 6
Product side: H is 4; S is 1; O is 4
Hydrogen is now out of balance, so a coefficient of 2 can be placed in front of H2S to give:
2H2S + 3O2 → 2H2O + SO2
Reactant side: H is 4; S is 2; O is 6
Product side: H is 4; S is 1; O is 4
Sulfur is unbalanced, so a coefficient of 2 can be placed in front of SO2 to give:
2H2S + 3O2 → 2H2O + 2SO2

A. Formed from magma that cooled slowly
B. Formed by pressure and heat over time
C. Formed from lava that cooled quickly
D. Formed by pieces of rock cemented together
Answers
Answer:
B
Explanation:
Cause metamorphic rock is formed by heat pressure overtime
The rock collected by Roger if it is metamorphic rock it is formed by pressure and heat over time. Hence, image image B represents a metamorphic rock.
What are metamorphic rocks ?Metamorphic rocks have undergone significant alteration from their igneous, sedimentary, or previous metamorphic forms. When rocks are exposed to extreme temperatures, high pressures, hot mineral-rich fluids, or, more frequently, some combination of these conditions, metamorphic rocks are created.
These kinds of conditions can be found deep inside the Earth or where tectonic plates collide. The process of metamorphism changes the rocks into denser, more compact rocks rather than melting them.
Either by the rearranging of mineral constituents or through chemical reactions with fluids that enter the rocks, new minerals are produced. Even rocks that have already undergone metamorphosis might undergo changes due to pressure or temperature. Many metamorphic rocks are bent, smeared out, and compressed.
Therefore, option B is correct.
