The volume% of acetone = Ml of acetone/Ml of solution x100
ml of acetone =200ml
ml of solution = 1.60 x1000=1600ml
volume% of acetone is therefore= 200/1600 x100= 12.5%
Answer:
Isotopes of an element have same number of protons but different number of neutrons. Which means isotopes of an element have same atomic number but different mass number.
The chemical property of an element is determined by the number of electrons. And as all the isotopes have same number of electrons, they have same chemical properties.
Thus as isotopes of an element have same atomic number , they have same number of electrons and protons. As they have different mass number, the number of neutrons will be different. Hydrogen has three isotopes ,
,
and
. Thus
has no neutron.
Sun. The sun is the producer because it is producing energy and sunlight for the organisms living on Earth
<h3><u>Answer;</u></h3>
EtO-PHE-NH2 + H+ _______ EtO-PHE-NH3+ Cl-
<h3><u>Explanation;</u></h3>
- <em><u>p-phenetidine is p-ethoxy aniline so the amino group acts as a base. The free electron pair on nitrogen will form a coordinate covalent bond with the H+ from the ionized HCl. </u></em>
- HCl is used for the acid-base reaction in p-phenetidine in amide synthesis of acetophenetidin rather than water becuase HCl's polarity contributes to a reaction driven to the right. It protonates the amine group, making it easy to dissolve.
