Answer:
4 enzymes responsible for digestion:
1. Salivary amylase ---- substrate: Starch ---- end-product: Maltose
2. Lipase ---- substrate: Lipids (fats and oils) ---- end-product: Fatty acids and glycerol
3. Maltase ---- substrate: Maltose ---- end-product: Glucose
4. Protease ---- substrate: Protein ---- end-product: Amino acids
The rate of doing work is called power of an object.
It is also defined as the work done by an object per unit time. Mathematically, its formula is given by :
, W is work done and t is time taken.
The SI unit of power is watts and its commercial unit is kWh.
1 watt = J/s or N-m/s.
Answer:
A
Explanation:
An unbalanced force is your answer.
H₂ is the limiting reactant.
<u>Explanation:</u>
H₂ reacts with O₂
The reaction would be
2H₂ + O₂ → 2H₂O
According to the balanced equation, 2 moles of H₂ reacts with 1 mole of O₂ to form 2 moles of H₂O.
The ratio of usage of H₂ and O₂ is 2 : 1 respectively
If 3 moles of H₂ and 2 moles of O₂ are present then:
3 moles of H₂ would require 1.5 moles of O₂ ( 2 : 1 of H₂ and O₂ )
Out of 2 moles of O₂, 1.5 moles would be used and 0.5 mole would be in excess.
Therefore, H₂ is the limiting reactant as the number of moles of H₂ are not enough to use all the O₂.

With: ![K_2=\frac{[NO_2}{[O_3][NO]}=5.8*10^{-34}](https://tex.z-dn.net/?f=K_2%3D%5Cfrac%7B%5BNO_2%7D%7B%5BO_3%5D%5BNO%5D%7D%3D5.8%2A10%5E%7B-34%7D)
To achive the reaction we combine those two reactions:
The equilibrium constant:
