What cellular component is responsible for energy production and metabolic processes?
AlekseyPX

The cellular component responsible for energy production and metabolic processes is mitochondria.

What is Mitochondria?

A double-membrane-bound organelle known as a mitochondrion is found in the majority of eukaryotic organisms. The majority of the cell's adenosine triphosphate, which is then used as a source of chemical energy throughout the cell, is produced by mitochondria using aerobic respiration.

Oxidative phosphorylation, which produces ATP using the energy released during the oxidation of the food we eat, is the traditional function of mitochondria. For the majority of biochemical and physiological processes, including growth, mobility, and equilibrium, ATP is used as the main energy source in turn.

How to find the valency of iron
anastassius [24]
When iron loses the 2 4s electrons, it attains a valency of +2. Sometimes, iron will also lose one of the paired electrons from 3d orbital, leaving the entire 3d orbital filled with unpaired electrons (which provides a more stable configuration). In this case, its valency will be +3.

Gaseous methane ch4 will react with gaseous oxygen o2 to produce gaseous carbon dioxide co2 and gaseous water h2o . suppose 1.44
Usimov [2.4K]
The balanced equation for the above reaction is;
CH₄ + 2O₂ ---> CO₂ + 2H₂O
Stoichiometry of CH₄ to O₂ is 1:2
The number of methane moles present - 1.44 g/ 16 g/mol = 0.090 mol
Number of oxygen moles present - 9.5 g/ 32 g/mol = 0.30 mol
If methane is the limiting reagent,
0.090 moles of methane react with 0.090x 2 = 0.180 mol 
only 0.180 mol of O₂ is required but 0.30 mol of O₂ has been provided therefore O₂ is in excess and CH₄ is the limiting reactant.
Number of moles of water that can be produced - 0.180 mol
Therefore mass of water produced - 0.180 x 18 g/mol = 3.24 g 
Therefore mass of 3.24 g of water can be produced
