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.
Answer:
b) 5.87 E23 molecules
Explanation:
∴ mm SO3 = 80.066 g/mol
⇒ molecules SO3 = (78.0 g)(mol/80.066 g)(6.022 E23 molec/mol)
⇒ molec SO3 = 5.866 E23 molecules SO3
It's in the periodic table.
See the attached picture. The number below 'Zn' is the molar mass. The closest answer choice is 65.38
Answer:
B. The substance is in the liquid state.
Explanation:
The symbol (l) in a chemical equation represents that the substance is in liquid state which is one of the physical states of a chemical substance.
The chemical element's atomic radius is measured by the size of its atoms, usually the medium or typical distance between the central nucleus and the surrounding electron shells. As the limit is not a well defined physical entity, different definitions of non-equivalent atomic radius exist.
Hope this helps!
