A researcher discovers a new bacterium that lives on the seafloor near hydrothermal vents. This organism reduces CO2 to form C6H

12O6 (glucose), and also derives energy from H2 (by oxidation). This bacterium is a:
A. photoautotroph.
B. chemoheterotroph.
C. chemoautotroph.
D. photoheterotroph.

Answer:

C. Chemoautotroph

Explanation:

The new bacterium are able to create their own energy and biological materials  (glucose) from inorganic chemicals (CO2 and H2), therefore they are called chemoautotroph.

How are tectonic plates related to earthquakes and volcanoes?
patriot [66]

Answer

Tectonic plates are parts of the earth's crust. There are cracks in these plates that allow magma to seep through and build-up which creates volcanic eruptions. Volcanos themselves are created by the earth's plates pushing against each other and slowly, over time, rising to create these large raises in the crust. Earthquakes are caused by these plates creating friction against one another until they forcefully overlap or rip apart, hence the shaking effect during an earthquake.

Discussion Questions 1. Given the equilibrium equation for a general reaction, A + B  C + D, explain what happens to the reacta
ANTONII [103]

Answer:The equilibrium constant for a given reaction is [concentration of products]/[concentration of reactants].

Explanation:

Equilibrium constant=[concentration of products]/[concentration of reactants]

The concentration of reactant  molecules is maximum at time 0 and it  decreases as the reaction proceeds, The concentration of product molecules increases.At equilibrium the concentration of reactants and products are equal.

All the changes would occur in accordance with the LeChateliers principle.

For the given reaction the following changes would occur:

a When CO is removed from the reaction mixture so the reaction would shift towards right that is in forward direction as we are decreasing the concentration of CO so the system would try to increase the concentration of CO and that can happen by more production of CO.

b Since the above reaction is an endothermic reaction so when we would be adding heat to the system that is when we would increase the temperature  the reaction would shift forwards as  more heat energy is absorbed by reactants  to form more products.

c When more CO₂ is added so more amount of reactants are added to the system so the system would try to decrease the amount of reactants that is CO₂ and hence more amount of products would be formed.The reaction would shift in forward direction.

d Since  this reaction is endothermic in nature so when we remove the heat from reaction hence even less amount of heat is present in the system and so the reaction shift in backward direction as the reaction cannot proceed without enough amount of heat.
