Answer: e. All voltaic (galvanic) cells involve the use of electricity to initiate nonspontaneous chemical reactions.
Explanation:
Electrochemical cell or galvanic cell or voltaic cell is a cell which converts chemical energy to electrical energy.
There are two electrodes in an electrochemical cell , where one is called as anode and one is called as cathode.
At cathode reduction takes place and at anode oxidation takes place.Thus the electrons generated at anode travel towards cathode and flow of electrons lead to generation of electricity.
Thus chemical reactions lead to generation of electricity.
Thus the statement that all voltaic cells involve the use of electricity to initiate nonspontaneous chemical reactions is false.
Answer:
D. The cork looked like tiny rectangular rooms
Explanation:
The invention that helped scientists discover the cell is the microscope. Tell why Hooke called the structures he saw in the cork cellular("small rooms"). He called them cellular because the box like cells reminded him of the monks monasteries.
Answer:
See explanation
Explanation:
Heat of formation, also called standard heat of formation, enthalpy of formation, or standard enthalpy of formation, the amount of heat absorbed or evolved when one mole of a compound is formed from its constituent elements, each substance being in its normal physical state (gas, liquid, or solid)(Encyclopedia Britannica).
The greater the magnitude of the negative value of the heat of formation(the more negative), the greater stability of the compound formed. Hence, a more negative heat of formation (a larger negative number) means that a compound is more stable than an isomer with a less negative heat of formation.
Answer:
i guess you mean its volume, so the answer is "shrunken" 3 times
Explanation:
from the equation pV=nRT, whatever happens to its pressure, the opposite happens to its volume.
