Answer: answer is a) an attractive force that usually involves a polarly-bonded hydrogen atom and another polarly-bonded atom with a partial negative charge
Explanation: hydrogen bond is a special type of bonding that closely resembles an ionic bond. It involves hydrogen atom and another highly electronegative atom, this bond is due to the the attraction between the slight positive charge on the hydrogen and the slight negative charge on the pairing atom.
Note that electron is not transfered as in ionic bonding.
Molucules with hydrogen bonding between their atoms includes water, hydrogen fluoride and ammonia.
Answer:
The pressure the hydrogen gas exerted before its volume was decreased is 2.7207 atm.
Explanation:
Using Boyle's law

Given ,
V₁ = 14.65 L
V₂ = 7.94 L
P₁ = ?
P₂ = 5.02 atm
Using above equation as:




<u>The pressure the hydrogen gas exerted before its volume was decreased is 2.7207 atm.</u>
Convert 50mL to liters by dividing it by 1000 to get your liters value which should be 0.05 L
Now your formula is .20 = x/0.05
Solve for x to get your mol value and you should get 0.01 mol
