Answer:
Molarityof the solution is 0.1375 M.
Explanation:
We will first find the number of moles of diethyl ether (C4H10O) by finding its molar mass and measured mass.
Molar mass of diethyl ether (C4H10O) = 74.12 g.
Now, volume of diethyl ether (C4H10O) = 1.15 mL and its density = 0.7134 g/mL.
Therefore, measured mass of diethyl ether (C4H10O) = volume x density = 1.15 mL x 0.7134 g/mL = 0.82 g.
Now, number of moles of diethyl ether (C4H10O) = 
= 0.011 Moles.
Volume of the solution = volume of diethyl ether + volume of dichloromethane = 1.15 mL + 78.85 mL = 80 mL.
Now, molarity of the solution = Number of moles of diethyl ether / Volume of the solution( in mL) x 1000 = 
Hello my friend, Ionic bond is created when one atom takes an electron from another to fill its valence shell. Hope it helps☺☺

Answer:
endothermic reactions
Explanation:
Endothermic reactions are those reactions that absorbs heat from the surroundings as opposed to the exothermic reaction that releases heat energy. This heat absorption that characterizes endothermic reactions causes the surrounding to be cool.
However, in an endothermic reaction, more energy is needed to be absorbed in order to break the bonds of the reactants to form products, hence, making the activation energy of endothermic reactions HIGHER.
