How is carbon moved from the hydrosphere to the atmosphere?

Chemistry
1 answer:
inessss [21]3 years ago
4 0

Answer:

Explained

Explanation:

the various ways of input of CO_2 into the atmosphere.

1.Dissolved  CO 2 in the ocean is released back into the atmosphere by heating ocean surface water

2.Plant and animal respiration, an exothermic reaction involving the breakdown into CO 2 and water of organic molecules.

3. Degradation of fungi and bacteria which are responsible for breaking down carbon compounds in dead animals and plants(fossils) and convert carbon into CO2 when oxygen or methane is present.

4.Combustion of organic matter (that includes deforestation and combustion of fossil fuels) oxidizing to produce CO2;

5. Cement production when calcium carbonate (limestone) is heated to produce calcium oxide(lime), cement component, and CO2 are released;

A 0.875-g sample of anthracite coal was burned in a bomb calorimeter. The temperature rose from 22.50 to 23.80°C. The heat capac
kherson [118]

Answer:

a) 26.65 kJ was the heat evolved by the reaction.

b) 3.046\times 10^7 kJ is the energy released on burning 1 metric ton  of this type of coal

Explanation:

Heat capacity of the calorimeter = C = 20.5 kJ/°C

Initial temperature of the calorimeter,T_1 = 22.50°C

Final temperature of the calorimeter,T_2 = 23.80°C

The heat evolved by the reaction = Q

Q=C(T_2-T_1)

Q=20.5 kJ/^oC\times (23.80^oC-22.50^oC)

Q=26.65 kJ

26.65 kJ was the heat evolved by the reaction.

0.875 g sample of anthracite coal was burned in a bomb calorimeter

0.875 g sample of anthracite coal gives 26.65 kJ of heat.

1 metric ton= 1000 kg

1000 kg = 1000 × 1000 g = 1,000,000 (1 kg =1000 g)

Then burning 1,000,000 g coal will give:

=\frac{26.65 kJ }{0.875}\times 1,000,000 g=3.046\times 10^7 kJ

3.046\times 10^7 kJ is the energy released on burning 1 metric ton  of this type of coal

Is bread a molecule or a compound
Papessa [141]

Answer:

Bread is a Molecule.

Explanation:

This is what I found.

Bread cannot be classified as a compound. Compounds are formed when two or more substances are bonded together chemically, however, mixtures are not chemically bonded.

The chemical building blocks of bread are proteins and starch. Starch molecules are long, chained polymers of simple sugars (such as glucose) joined end to end by chemical bonds. Proteins on the other hand are more complex, made up of varying combinations of different amino acids.

Hope this helps.
