A reaction in which energy is absorbed from the surroundings is called anendothermic<span> reaction. In </span>endothermic<span> reactions the enthalpy of the products is greater than the enthalpy of the reactants. Because reactions release or absorb energy, they affect the temperature of their surroundings.

Heya!!!
Answer to your question:
A catalyst is ______
B. Not used up in a reaction.
Catalyst do not change the amount of reactants or products or itself get used but it just change the rate of reaction.
Hope it helps *_*
A redox reaction be used as a source of electrical energy only when two half-reactions are physically separated. <span>The electrons that are released at the anode flow through the wire, producing an electric current. Galvanic cells therefore transform chemical energy into electrical energy that can then be used to do work.</span>
Molarity of solution = 0.08 M
<h3>Further explanation </h3>
Molarity shows the number of moles of solute in every 1 liter of solution or mmol in each ml of solution
Where
M = Molarity
n = number of moles of solute
V = Volume of solution
Volume of solution = 100 ml + 150 ml = 250 ml
