Explanation:
Heating the liquid will increase vibration between the molecules of thick liquid. As a result, kinetic energy of molecules will increase and viscosity of liquid will decrease.
Therefore, force of attraction between the molecules of thick liquid will decrease and it will start to flow easily.
Thus, we can conclude that by heating the liquid, Valerie can easily pour the liquid into a beaker.
Ba(OH)2 + 2 HNO3 -----> Ba(NO3)2 + 2 H2O
1) Calculate moles of Ba(OH)2 used.
0.65 mol / L x 0.0234 L = 0.01521 mol Ba(OH)2
2) Calculate moles of HNO3 used.
0.01521 mol Ba(OH)2 x 2 HNO3 / 1 Ba(OH)2 = 0.03042 mol HNO3
3) Calculate molarity of HNO3.
0.03042 mol / 0.0425 L =
so the answer is 0.716 M !
