How does the greenhouse effect relate to the theme of stability and change

1 answer:

8 0

The greenhouse effect increases the temperature of the Earth by trapping heat in our atmosphere. This keeps the temperature of the Earth higher than it would be if direct heating by the Sun was the only source of warming.
When the sunlight reaches the surface of the Earth, some of it is absorbed which warms the ground and some bounces back to space as heat. Greenhouse gases that are in the atmosphere absorb and then redirect some of this heat back towards the Earth.

Match each process to where it occurs in the carbon cycle

oksano4ka [1.4K]

Carbon enters the atmosphere by respiration.

Carbon dioxide is absorbed by producers in photosynthesis.

Then carbon transfers from organism to organism from animals eating the plants then the animals eating the other animals.

Then the animals and plants die and decomposes release CO2 back into the atmosphere to start the process again.

Balance the follwing equation:

MatroZZZ [7]

Answer:

- in order to balance the chemical equation, you need to make sure the number of atoms of each element on the reactant side is equal to the number of atoms of each element on the product side.

equation: (given)

__ C + __ H2 --> __ CH4

C = 1 | C = 1

H = 2 | H = 4

so, here we can see that the number of hydrogen (H) atoms are NOT equal, which means we have to put a number infront of the compounds inorder to balance it. this means putting a coefficient.

equation: (balanced)

C + 2H2 + CH4

- the only thing added was the 2.

-- let me know if you have any questions about this.

In both trials, you started with the same amounts of nitrogen and oxygen atoms. In this situation, did the equilibrium amounts c

sergiy2304 [10]

Answer:

No.

Explanation:

The equilibrium amounts relatively do not change depending on the reaction, whether you started with 8 moles of NO2 or 4 moles of NO2.

Give reasons :

Elza [17]

Ans 1:

Ammonia is not collected over water since it is highly soluble in water

Ans 2:

Ammonia gas is lighter than air and hence collected by the downward displacement of air.

Ans 3:

The carbon dioxide is very cold as it comes out of the extinguisher, so it cools the fuel as well.

Ans 4:

H₂SO₄ is not used in the preparation of carbon dioxide Because the calcium sulphate formed is insoluble in water. So, CO₂ will not form.

Ans 5:

The opening of hard glass test tube is slanted down during laboratory preparation of ammonia gas because Ammonia gas is not collected in the gas jar by upward displacement of air because it is lighter than air

Ans 6:

Magnesium is reactive enough to be combusted and oxidized in a reaction with carbon dioxide:

The magnesium strip burns brightly in the air, but continues to burn in the carbon dioxide environment
