Yes it is, because lucid means characterized by clear perception.
Answer:
b) It produces electrical current spontaneously.
Explanation:
Cells capable of converting chemical energy to electrical energy and vice versa are termed Electrochemical cells. There are two types of electrochemical cells viz: Galvanic or Voltaic cells and Electrolytic cells. Voltaic cell is an elctrochemical cell capable of generating electrical energy from the chemical reaction occuring in it.
The voltaic cell uses spontaneous reduction-oxidation (redox) reactions to generate ions in a half cell that causes electric currents to flow. An half cell is a part of the galvanic cell where either oxidation or reduction reaction is taking place. Hence, the spontaneous production of electric currents is true about Voltaic/Galvanic cells.
Answer:
One CME is produced every five days
Explanation:
A. is the correct answer.
For every two molecules of water formed, one hydrogen atom is needed.
Answer: Option C.
<u>Explanation:</u>
The water particle is very simple and basic. A particle is a bit of issue that contains at least two iotas. The logical name for water is H2O. It is called H2O since it has two iotas of hydrogen (H) and one molecule of oxygen (O). There are a great many these atoms in a single drop of water.
A water molecule is formed when two atoms of hydrogen bond covalently with an atom of oxygen.
