The mitochondria is known as the “powerhouse of the cell." Why?*
Triss [41]

Answer:

The correct answer is - glucose is broken down into cellular energy (ATP).

Explanation:

Mitochondria is the double membrane cell organelle presents in all eukaryotic cells that produce the energy by the process of cellular respiration from the food to the cell to perform its day to day functions.

The cellular respiration is the process that involves the braking of the sugars into simple molecules and these catabolic reaction produce energy with CO2 and water as waste. The energy is stored in the form of ATP which is generated in the inner membrane of mitochondria. ATP is used by the cell to perform its function.

Thus, the prower house of the cell is mitochondria.

Why were Indians against building the Klamath river dam?
Hatshy [7]
Toxic water quality in the Klamath River is a direct result of both upper basin agricultural development (the draining of wetlands and intense chemical use), and the presence of PacifiCorp's dams, creating warm, stagnant pools for algae to develop. Massive algae pools in Upper Klamath Lake.

How is enthalpy used to predict whether a reaction is endothermic or exothermic?
Radda [10]

<u>Answer:</u>

<em>329.48 KJ/mol heat is released by the combustion of 2 molof methane</em>

<u>Explanation:</u>

The value of enthalpy determines whether the reaction is exothermic or endothermic. If the enthalpy change is positive, then the reaction is endothermic (heat or energy released) and if the enthalpy change is negative then the reaction is exothermic (heat or energy absorbed).

2CH_4(g)+4O_2(g) => 2CO_2(g)+4H_2O(g)

\Delta H \ reaction=[ 2(\Delta HfCO_2)+ 4(\Delta HfH_2O)]-[2(\Delta HfCH_4)+4(\Delta HfO_2)]

                            =2 ( -(393.5 KJ)/mol)-[2( -74.6 KJ/mol)+4(-241.82 KJ/mol)]

                            = -787 KJ/mol-[ -149.2 KJ/mol-967.28 KJ/mol]

                           = -787 KJ/mol+1116.48 KJ/mol

                                          =329.48 KJ/mol

<em>In this question, </em><em>the enthalpy of formation</em><em> has positive value and hence the </em><em>reaction is endothermic</em><em> in which the heat is released. </em>
