40 mi/gal * 1.61 km/mi * 0.264 gal/li
40*1.61*0.264
17 km/li
The process is know as diffusion in which substances move from higher concentration to lower concentration
Answer:
A microorganism, or microbe, is a microscopic organism, which may exist in its single-celled form or a colony of cells.
Explanation:
Answer:
C) exothermic
Explanation:
The given reaction is exothermic.
N₂ + 3H₂ → 2NH₃ + ENERGY
when energy is released the reaction is exothermic and when energy is written on left side with reactant it means energy is added and reaction is endothermic.
Exothermic reaction:
The type of reactions in which energy is released are called exothermic reactions.
In this type of reaction energy needed to break the bonds are less than the energy released during the bond formation.
For example:
Chemical equation:
C + O₂ → CO₂
ΔH = -393 Kj/mol
it can be written as,
C + O₂ → CO₂ + 393 Kj/mol
At an optimum pH of 7.0, there are more molecules per minute in all amounts of substrate thus this pH is ideal for maximum growth. 5. Enzymes function most efficiently at the temperature of a typical cell, which is 37 degrees Celsius. Increases or decreases in temperature can significantly lower the reaction rate.
