Here is the names and matches of butane methane ethane propane
The gastric chief cells of the stomach secrete enzymes for protein breakdown (inactive pepsinogen, and in infancy rennin). Hydrochloric acid activates pepsinogen into the enzyme pepsin, which then helps digestion by breaking the bonds linking amino acids, a process known as proteolysis.
If you leave the plant in the closet it will die due to the lack of sunlight and water it needs.
Yes, you could begin to swear because you are used to hearing those words so in your mind it will get implanted and it will be just a natural response.
Happy studying ^_^
Electrolytes are those which dissociates in solution and produces ions.
Ions can carry current,so Electrolytes conduct electiricity.
And non electrolytes are those which do not dissociate in solution and doesnt produce ions.
Since non electrolytes do not produce ions they cannot conduct electricity.
<u>Hence the right option is:</u>
B) Non-electrolytes dissolve and do not dissociate in water providing no charged ions to conduct electricity.
Answer:
84.24 g
Explanation:
Given data:
Mass of oxygen = 75 g
Mass of Al required to react = ?
Solution:
Chemical equation:
4Al + 3O₂ → 2Al₂O₃
Number of moles of oxygen:
Number of moles = mass/ molar mass
Number of moles = 75 g/ 32 g/mol
Number of moles = 2.34 mol
Now we will compare the moles of oxygen with Al.
O₂ : Al
3 : 4
2.34 : 4/3×2.34 = 3.12 mol
Mass of Al required:
Mass = number of moles × molar mass
Mass = 3.12 mol × 27 g/mol
Mass = 84.24 g
