Answer:

The reaction would be 1500n (equal reaction)

Explanation:

This can be explained by Newton's third law of motion which states that for every action (force), there is an opposite and equal reaction. In other words, when two objects or people come in contact, the magnitude of force which they exert on each other is equal and they both feel an equal reaction force.

It doesn't matter whether one of the colliding bodies is of bigger mass than the other.  This Newton's third law of motion is also known as the law of action and reaction.

What is the molarity of a 27.0% (v/v) aqueous ethanol solution? the density of ethanol (c2h6o, molar mass 46.07 g/mol) is 0.790
RoseWind [281]
   The  molarity  of a  27%(v/v) aqueous  ethanol  solution  is 4.63 M

         calculation
convert  27%(v/v) to  fraction  = 27ml/100 ml

use  density to  convert  27ml  to grams =  27 ml  x0.79 g/ml = 21.33 g

find  the number  of moles  of C2H6O

moles = mass/molar mass of C2H6O(46.07 g/mol)

moles is therefore = 21.33 g /46.07 g/mol =0.463  moles

find the  molarity =   moles /volume in liters

volume in liter =  100 ml/1000 = 0.1 L

molarity  is therefore =  0.463 mole/0.1 L = 4.63  M

In a coffe cup calorimeter, 50.0mL of 0.100M of AgNO3 and 50mL of 0.100M HCl are mixed to yield the following reaction:
Jet001 [13]

Answer:

The enthalpy change of the reaction is -66.88 kJ/mol.

Explanation:

Mass of the solution = m = 100 g

Heat capacity of the solution = c = 4.18 J/g°C

Initial temperature of the solutions before mixing = T_1=22.60^oC

Final temperature of the solution after mixing = T_2=23.40^oC

Heat gained by the solution due to heat released by reaction between HCl and silver nitrate = Q

Q=m\times c\times (T_2-T_1)

Q=100 g\times 4.18 J/g^oC\times (23.40^oC-22.60^oC)=334.4 J

Heat released due to reaction = Q' =-Q = -334.4 J

Moles of silver nitrate = n

Molarity of silver nitrate solution = 0.100 M

Volume of the silver nitrate solution = 50.0 mL = 0.050 L ( 1 mL = 0.001 L)

Moles =Molarity\times Volume (L)

n=0.100 M\times 0.050 L=0.005 mol

Enthalpy change of the reaction = \Delta H

=\Delta H=\frac{-334.4 J}{0.005 mol}=-66,880 J/mol=-66.88 kJ/mol

1 J = 0.001 kJ

The enthalpy change of the reaction is -66.88 kJ/mol.
