Answer:
See the answer below, please.
Explanation:
Take as an example a light bulb inside a lamp to illuminate a room. When you plug it in a plug and turn it on, light is generated. More precisely, heat (Joule effect) is produced inside the lamp by its internal filament (conductive material) when it passes through the electrical energy, generated by the friction of the atoms that are inside it when it encounters a resistance.
Answer:
Explanation:
When there is difference between the concentration of the content of a cell and the solution surrounding the cell, there will be an Electrochemical gradient or Concentration gradient. Therefore, some solute will tend to move from the region of high concentration to the region of lower concentration through the cell membrane.
Such a movement is called Primary Active Transport

Answer:
126.4 g of 
are required
Explanation:
Balanced reaction: 
According to balanced reaction-
8 moles of 
are produced from 2 moles of
So, 8.70 moles of are produced from 
moles of or 2.175 moles of
Molar mass of = 58.12 g/mol
So, mass of required = 
= 126.4 g
Hence 126.4 g of are required
