Answer: intermolecular forces are described as forces that either cause attraction or repulsion between neighbouring particles or molecules
Explanation: liquids with strong intermolecular forces has the following properties:
1.) High boiling point
2.) high surface tension
3.) Low viscosity
4.) Low vapour pressure
While liquids with weak intermolecular forces has the following properties:
1.) Low boiling point
2.)low surface tension
3.) High viscosity
4.) High vapour pressure.
Answer:
59.2 grams
Explanation:
We are given that 70.4% of the weight of the total 200 g of the concentration is made up of nitric acid, the remaining information is not required to solve the problem. Since water and nitric acid are the only components of the solution, the total weight of water is given by:
There are 59.2 grams of water in this solution.
Answer:
Pressure = 0.64 atm
Explanation:
Use Ideal Gas Law PV = nRT => P = nRT/V
n = moles CO₂(g) = 66g/44g/mol = 1.5 mol CO₂
R = Gas Constant = 0.08206 L·atm/mol·K
T = Temperature = -14.5°C = (-14.5 + 273)K = 258.5 K
V = 50.0 Liters
P = (1.5 mol)(0.08206 L·atm/mol·K)(258.5 K)/(50.0 L) = 0.64 atm
Hydrogen bonding is a type of intermolecular forces of attraction in which hydrogen atom is bonded to one of the most electronegative atoms. This gives a partial positive charge to hydrogen atom and a partial negative charge to the electronegative atom involved in the bonding. The electronegative atoms that can form hydrogen bonding are fluorine (F), nitrogen (N), and oxygen (O).
Therefore the correct option is,
A) NH3
