Answer:
We don't have the passage. A random sampling of surfactant uses includes:
- removal of oily materials from objects (clothes and dishes)
- forms remarkable structures called bubbles
- Assists in forming emulsions (e.g., mayonaise and paints)
Explanation:
The structure of a surfactant makes one end of a molecule hydrophilic and the other end hydrophobic. In water, they self-assemble into micelles, an arrangement in which the hydrophobic ends align towards the center, and the hydrophilic ends are pointed outwards to the water. This self-assembly is apparant when bubbles are made. The molecules quickly align themselves such that the hyrophilic ends are oriented inwards towards a thin layer of water and the hydrophobic ends are pointed outward to the air. This arrangement allows a mono-molecular sphere of water molecules to remain stable enough to float, reflect light, and please. These same properties allow the inverse to occur. Soap molecules surround a hydrophobic mass (e.g., the hamburger grease on your shirt) and solubilize it into small micelles which are then carried away in the surrounding water.
Answer:
Maximum mass of produces=50.8g;
Explanation:
Firstly balance the chemical reaction,
Molecular weight of =334g/mole;
Molecular weight of CO =28g/mole;
Number of mole of given=80g/(334g/mole)=0.239mole;
Number of mole of CO given=28g/(28g/mole)=1 mole
Moles are:
Number of mole of =0.239
Number of mole of CO=1;
From the balanced equation,
1 mole of reacts with 5 moles of CO;
Hence;
0.239 mole of will react with 5*0.239 moles of CO means
Moles of CO that reacts with =1.2 mole but we have given 1 mole therefore
Will be excess reagent and CO will be the limitting reagent
And mass of product depends on limiting reagent i.e. mass of CO.
5 mole of CO produces 1 mole of
;
1 mole of CO produces 1/5 mole of ;
Maximum mass of produces=mole*molecular weight;
Molecular weight of =254g/mole;
Maximum mass of produces = (1/5)*254=50.8g;
Maximum mass of produces=50.8g;
