Answer:
Hydrochloric acid is a strong acid with a distinct pungent smell and it is highly reactive while Sodium hydroxide is a strong base and it is fully Ionic
Answer and Explanation:
Dipole-Dipole interactions are <u>weaker than</u> hydrogen bonds.
Hydrogen bonds are a form of dipole-dipole interactions, being the strongest form of dipole-dipole interactions.

The question is: To neutralize 20ml of 0.1M HCl solution, 10ml of NaOH solution of concentration x mol/l is required. What is the value of x?
Answer: The value of x is 0.2 M.
Explanation:
Given: 
= 20 mL, 
= 0.1 M
= 10 mL, 
= x
Formula used is as follows.
Thus, we can conclude that the value of x is 0.2 M.
The equation in this problem is: 2Pb(NO3)2(s) --> 2PbO(s)
+ 4NO2(g) + O2(g)
And the question is what the pressure in the cylinder is
after decomposition and cooling to a temperature of 300 K.
Solution:
Moles of Pb (NO3)2 = 3.31/331 = 0.0100
2 moles of Pb (NO3)2 will decay to mold 4 moles of NO2 and 1 mole of O2. So
0.0100 moles of Pb (NO3)2 will form 0.02 moles of NO2 and 0.00500 moles of
O2
Then use the formula: PV = nRT.
P = (0.02 + 0.005) * 0.082 * 300 / 1.62
= 0.380 atm
