B.) 2,000 mL is equal to 2 L.
Answer: bạn viết phương trình Phenol + NaOH
=> nNaOH = nPhenol = 0,2 mol
m Phenol = 0,2x94 = 18,8 gam
%mPhenol = 18,8/28,9% = 65,05
Explanation:
Answer: Yes
Explanation:
This simulates the way offspring are formed by sperm from the male fish combining randomly with eggs from the female fish.
Answer:
The movement of electrons is kinetic energy, capable of producing electrical energy (option B).
Explanation:
An electron is a mobile subatomic particle, located outside the atom and forming elliptical orbits, unlike protons and neutrons. In addition, each electron has a negative charge.
<u>The energy on which the movement of the electrons depends is kinetic energy, which promotes this movement</u>. The interaction between the negative charges of the electrons and the positive charge of the protons produces electrical energy.
<em>The other options are not correct because the charge energy, electric energy and magnetic energy are consequences of the activity of the subatomic particles of the atom.</em>
