Rubbing alcohol is a solution
Answer:
14.33 g
Explanation:
Solve this problem based on the stoichiometry of the reaction.
To do that we need the molecular weight of the masses involved and then calculate the number of moles, find the limiting reagent and finally calculate the mass of AgCl.
2 AgNO₃ + CaCl₂ ⇒ Ca(NO₃)₂ + 2 AgCl
mass, g 6.97 6.39 ?
MW ,g/mol 169.87 110.98 143.32
mol =m/MW 0.10 0.06 0.10
From the table above AgNO₃ is the limiting reagent and we will produce 0.10 mol AgCl which is a mass :
0.10 mol x 143.32 g/mol = 14.33 g
Answer:
B
Explanation:
I had tried my best to get this answer and I had gotten B
sorry if it was not the right answer but I would recommend B
An electric motor produces heat while running. The amount of heat is roughly equivalent to the amount of power delivered to the motor.
It shows that the sodium atom has 11 protons and 12 neutrons, arranged in a ball shape.
