0.398=mol/4.57L. mol= 1.818. 1.818*3=5.456. 5.456/(4.57L)=1.19 M
Answer:
The mass of the reactants equals the mass of the products.
Each Ba(OH)2 requires 2 Cl to produce one BaCl2 molecule.
<span>The 2 H's from the 2 HCl molecules combine with the 2 (OH) to form 2 H2O molecules. </span>
<span>2 HCl (aq) + Ba(OH)2 (s) ==> BaCl2 (aq) + 2 H2O (l)
I hope the answer will help you. </span>
Answer:
C
Explanation:
Hydronium (H₃O+) is the same as H+ (aq) because of the same net charge. The acidic property of a solvent or solution is governed the amount of H+ ion in it. The higher the H+ ions the lower the pH. In pure water H₃O+ and OH- are in equal amount. More of OH- ions turn the solution basic.
Answer:
Vapor pressure of Eugenol = 667.04torr
Explanation:
By applying dalton's law of partial pressure;
at 100degree celsius, total pressure = 744.67torr
vapor pressure of water at 100 degree celsius = 760torr
mole fraction of eugenol = 0.1648
mole fraction of water = 1 - 0.1648 = 0.8352
Total pressure = vapor P(water) + vapor P( Eugenol)
for water; vapour pressure = mole fraction x total pressure
for eugenol; vapor pressure = mole fraction x total pressure
substituting into the above gives the vapor pressure of eugenol = 667.04torr
