Barium chloride reacts with silver nitrate to form a precipitate of silver chloride along with soluble solution of barium nitrate. The equation is as follows:
BaCl2(aq) + AgNO3(aq) → AgCl(s) + Ba(NO3)2(aq)
Lets balance the equation:
Reactants Products
# Ba atoms = 1 #Ba atoms = 1
# Cl atoms = 2 # Cl atoms = 1
# Ag atoms = 1 # Ag atoms = 1
# NO3- group = 1 # NO3- group = 2
Thus the balanced equation needs to be balanced w.r.t Cl and NO3-
BaCl2(aq) + 2AgNO3(aq) → 2AgCl(s) + Ba(NO3)2(aq)
Answer:
- The molecules stick together and form a solid making ice
- By removing heat
Answer:
The concentration of the magnesium fluoride solution is 0.0020 M
Explanation:
Step 1: Data given
Mass of MgF2 = 0.031 grams
volume = 250 mL = 0.250 L
Molar mass of MgF2 = 62.3 g/mol
Step 2: Calculate moles
Moles MgF2 = mass MgF2 / molar mass MgF2
Moles MgF2 = 0.031 grams / 62.3 g/mol
Moles MgF2 = 4.98 *10^-4 moles
Step 3: Calculate concentration of MgF2
Concentration MgF2 = moles MgF2 / volume
Concentration MgF2 = 4.98 *10^-4 / 0.250 L
Concentration = 0.0020 M
The concentration of the magnesium fluoride solution is 0.0020 M
Answer:
The relative strength of the four intermolecular forces is: Ionic > Hydrogen bonding > dipole dipole > Van der Waals dispersion forces. ...
Boiling points increase as the number of carbons is increased.
Branching decreases boiling point.
