Answer:
It increases in value positively
Explanation:
The entropy of a chemical reaction can be defined as the degree of disorderliness. Hence when we talk about entropy, we are talking about the degree of randomness associated with that specific chemical reaction. The burning of wood is a kind of spontaneous reaction.
For a reaction to be spontaneous, the change in free Gibbs energy must be negative. To make this a reality, at constant enthalpy, the reaction temperature and change in entropy is expected to be negative in value. To get this negative value needed, it is essential know that the value of the entropy must increase as the temperature of the burning wood is increasing too.
Answer:
Sn^2+(aq)/Sn^3+(aq)//F2(g)/2F-(aq)
Explanation:
In writing the shorthand notation for an electrochemical cell, the oxidation half cell is shown on the left hand side and the reduction half cell is shown on the right hand side. The oxidation half equation reflects electron loss while the reduction half equation reflects electron gain.
Answer:
Primary active transport
Explanation:
In a cell, the movement of molecules like calcium ions (Ca²⁺), <em>to a region having high solute concentration from a region having low solute concentration, through the cell membrane requires metabolic energy</em> and is known as Primary active transport.
It is given that the concentration of calcium in the cell (0.3%) is greater than the concentration of calcium in the fluid surrounding the cell (0.1%). <em><u>So the calcium ions move into the cell and the cell obtains more calcium. </u></em>
<u>Therefore, the cell obtains more calcium by the process of Primary active transport.</u>
The heat released from fission reactions is used to change water into steam. The steam then turns the blades of a turbine to generate energy. The answer will hence be B. Quickly moving neutron coming out of the reaction are slowed down by water. The water heats up and turns into steam. The steam turns the turbine and produces electricity.
Answer:
Therefore the Chlorine electron configuration will be 1s22s22p63s23p5. The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom.
