The following are the steps involved in drawing Lewis structure of the polyatomic trisulfide anion
:
Total number of valence electrons = 
Resonance is not possible in this ion. The molecular geometry of the ion will be bent as there are two lone pairs and two bond pairs on the central atom.
Answer:
Although PPT was initially prepared from terephthalic acid (TPA) and 1,3-propanediol (PDO) in the 1950s, it has been mainly synthesized by transesterification of PDO with dimethyl terephthalate (DMT) similar to poly(ethylene terephthalate) (PET) and poly(butylene terephthalate) (PBT).
Explanation:
I can't answer this question without knowing what the specific heat capacity of the calorimeter is. Luckily, I found a similar problem from another website which is shown in the attached picture.
Q = nCpΔT
Q = (1.14 g)(1 mol/114 g)(6.97 kJ/kmol·°C)(10°C)(1000 mol/1 kmol)
<em>Q = +6970 kJ</em>
Answer:
chloroplast, more precisely in the stroma of the chloroplast
Explanation:
Chloroplasts are a type of chromoplasts that are located in photosynthetic plant cells and green algae.
They can be moved by amoeboid and contractile movements, and placed in the part of the cell that receives the most light. Photosynthetic algae usually have a large chloroplast, but plant cells have a few tens.
The internal medium of the chloroplast is called stroma, and it is composed of a solution of carbohydrates, lipids, protids, nucleic acids, pigments, nucleotides, salts and elements.
Its main function is to capture the light energy and use it in the synthesis of organic matter.
